The Chernobyl Disaster And Its Effects On The United States
Three Mile Island As humans we want to have a good life, have a home, maybe a family and feel
safe. With the advances in industry such as energy production we can have more luxuries which
include heat, lights and running water. However, as technology gets bigger and better there will
always be risks that can lead to catastrophic outcomes. Luckily for the United States; we did not
have a disastrous outcome with a nuclear power plant such as the 1986's Chernobyl Nuclear Power
plant catastrophe, making, "the Chernobyl disaster the only level 7 incident on the International
Nuclear Event Scales (INES) making it the biggest man–made disaster of all time" (List 25, 2014) .
Three Mile Island power plants is located near Middletown Pennsylvania. On March 28, 1979, the
plant had a partial meltdown. Even though the Three Mile Island power plant incident did not have
any adverse health effects, Three Mile Island had an impact on the nuclear industry development
and politically in the United States.
To understand the Three Mile Island incident, a background knowledge is needed. What is a nuclear
power plant? Nuclear power plants are energy producing facilities. The energy is produced in a
nuclear reactor located in the facility. The plants use heat generated from nuclear fission which
occurs in a contained area and in which water is converted to steam. Nuclear fission is the division
of a nucleus in two approximate equal masses. When this process is completed a release of a large

The Chernobyl Nuclear Disaster And Its Effects On The World
On April 26th, 1986, at 1:23 A.M., the world's worst nuclear disaster to date occurred. It has affected
millions of people in Eastern Europe, and it has caused more than 360,000 people to evacuate their
homes and leave their belongings behind. It has also set a dangerous precedent to the safety and
operating procedures of other nuclear power plants around the world. Thirty years later, people in
Eastern Europe are still feeling the effects of the Chernobyl Nuclear Power Plant. The causes, the
effects on animals and the environment, and the effects on humans of the Chernobyl Nuclear
Disaster are still being debated by scientists today. The causes of the Chernobyl Nuclear Disaster
involve the analysis of views, design deficiencies, operator errors, and the cleanup of the disaster.
When the accident happened, there were many different views and ideas of what happened. One
idea was that there was damage to the cooling system, and too much pressure built up in the shell of
the reactor, causing the hydrogen that was leaving and the air that coming in to mix and cause the
explosion ("Causes and Impact" 18). The other view on the accident, was human error due to tests
and experiments ("Causes and Impact" 18). It was determined that it was the operator's errors and
the design of the reactor, which had a safety features, which caused the disaster ("Causes and
Impact" 17). The Chernobyl Nuclear Power Plant used a different design compared to other nuclear
plants around the world.

The Disaster at Chernobyl
On April 26th, 1986, operators at the Chernobyl Power Plant in Chernobyl, Ukraine, ran what they
thought to be a routine safety test. But fate was not on the side of these operators. Without warning,
reactor #4 became unstable, as it had been operating at a low power for a possible shutdown and the
reactor's design caused it to be unsafe at this level of power. Internal temperatures rose. Attempts to
cool the system produced the opposite effect. Instantly, the nuclear core surged with power. At 1:23
p.m., the reactor exploded. The first blast ripped off the reactor's steel roof. The second blast
released a large plume of radiation into the sky. Flames engulfed the building. For ten long days, ...

While some of the radiation lasted only for a few weeks, radioactive cesium–137 contaminated the
ground, plants, animals, and people with particles that produce destructive energy waves for 30 or
more years. Over time, both kinds of radiation can cause cancer and other diseases.[2] Patricia
Doyle, president of the Chernobyl Children's Project which aids victims of the Chernobyl accident
said, "The Chernobyl accident resulted initially in an epidemic of thyroid cancer in the surrounding
region. While that has subsided, physicians have been seeing an increase in tumors of all types
caused by exposure to the radiation that remains in the soil."[3] According to a statistic from the
Belarus Ministry of Health quoted during a field visit in January 1999, only 15% of the children
between the ages of 5 and 15 are in "good health." [4]
The regions commonly identified as experiencing the greatest contamination include the oblasts
(regions) of Homyel', Mahilyow, and Brest in southern and eastern Belarus; Kyiv, Zhytomyr, and
Chernihiv in northern Ukraine; and Bryansk in southwestern Russia.[5] Many of the effects on
public health are difficult to determine. While many health concerns are the cause of overexposure
to radiation from the accident, poor nutrition, the generally low level of health, and stress and
anxiety produced by fear of radiation exposure may all also be factors.

The Factors Leading to the Chernobyl Disaster Essay
The Chernobyl disaster on April 26, 1986 was one of the most dangerous nuclear explosions this
world has ever seen, and some people are still paying the price. This disaster not only affected
Europe, it affected the whole world. This was during the time of the Cold War, and it government
corruption. The April 1986 disaster at the Chernobyl nuclear power plant in Ukraine was the product
of a flawed Soviet reactor design RBMK (reaktor bolshoy moshchnosti kanalniy) coupled with
serious mistakes made by the plant operators. "It was a direct consequence of Cold War isolation
and the resulting lack of any safety culture" (world–nuclear par 2). This disaster was caused by
multiple things, human error among them. According to World Nuclear ... Show more content on

This was a mistake because the reactor was never meant to operate at a level that low. That is what
caused the reactor to fill with water. The RBMK reactor is dangerously unstable when filled with
water. The operator tried but could not get the water levels into control, causing the reactors to
become even more unstable. With all the water going into the reactor, water flow was reduced
causing the power levels to slowly increase. The operator quickly tried to shut down the reactor
manually, but that caused the power levels to spike. "In the end the reactor had reached 120 times its
full power" (library.thinkquest). All the radioactive fuel that was sitting in the bottom of the reactor
disintegrated and pressure from the steam blew the top off the reactor. "All of this plus a serious
violation of safety, bad control systems, and flaws in the designs are what led to the horrible
increase of power which led to core meltdown" (pubs.acs.org). The steam explosion caused some of
a nearby building to break. The explosion caused radioactive material to be hurdled out into the sky.
Fires broke out inside and outside the reactor. Later that night the fire fighters had put the fires out,
but it still took about ten days for the helicopters to drop materials on the graphite fire to reduce
radiation release. The movement of radiation in the sky continued until June

The Chernobyl Nuclear Disaster
*Works Cited Not Included Chernobyl is a popular nuclear disaster it was a terrible technological
disaster. Chernobyl is a small town in the Ukraine. The closest major city is Kiev. Kiev is the capital
of the Ukraine. It is made up of 2.4 million people. In 1986 April 26 Chernobyl experienced an
unforgettable nuclear disaster. At the time, the USSR was responsible for roughly 10% of the
world's nuclear power. The year of the accident Chernobyl nuclear power plant was using four of the
most modern soviet reactors, the RBMK–type.
The cause of this tragedy was due to operator error. The nuclear operators were running a test to

The Soviets put only the bottom pipes in containment because this was easier. The main weakness
was in shutting the reactor down. As a result of inadequacy the shutdown rods are part of the normal
plant control system rather than being a separate emergency system. Again a fault in the control
system also makes the emergency shutdown unable to function. Another weakness was that
Chernobyl had only partial containment. Because of the partial containment the radiation went out
the top of the reactor where there were no leak tight boxes. The hot fuel and graphite were exposed
to air when they went out the top of the reactor. If there had been a completed containment, then the
water and steam from the broken pipes would have dissolved almost all of the cesium and
radioactive iodine that escaped. Even if the containment leaked the cesium and the iodine would not
get out. Because the hot fuel and graphite were exposed to air this chemical reaction did occur. The
operators had removed all of the control rods except for six. This action is against procedures. It is
not safe for any reactor to operate with so many control rods removed. Besides the RBMK reactor
was not designed to operate at such low power. The power generators of this reactor were run by
steam forced through turbines. By the time the reactor exploded none of the turbines were turning
and all of the steam was building.

Vladimir Shahsenock: The Chernobyl Disaster
Do you know anyone that has survived a disaster? They are not alone, take chernobyl for an
example. Vladimir Shahsenock passed away from the horrible accident. Someone who tried to
prevent this accident was Nikolai Gorbachenko. When the accident occurred Anolatly Dyatlov was
running the control room. It would be scary to be involved in a disaster like this one. Vladimir
Shahsenock died because of the disaster. He was working as a systems adjuster at the time of the
disaster. But at the time of the reactor explosion he was supposed to be under the reactor in the room
below. But he was doing something else at the time so he put it aside. But after he heard the
explosion he checked the radiation levels. The levels of radiation were crazy high.

Chernobyl : The Chernobyl Nuclear Disaster
Chernobyl was a catastrophic nuclear accident that occurred April 26th, 1986 at the Chernobyl
Nuclear Power Plant in the town of Pripyat, Ukraine. Chernobyl is the worst nuclear disaster in the
world in terms of cost and causalities. 31 people died as a direct result of the explosion – all of
whom were reactor staff and emergency workers. Until the 2011 Fukushima Daiichi nuclear
disaster, Chernobyl was the only nuclear accident classified as a level 7 event (the maximum
classification) on the International Nuclear Event Scale. The Chernobyl accident was the outcome of
a extremely flawed Soviet–era reactor design called RBMK as well as faulty and careless actions of
the under educated and under trained operators. RBMK –which translates to "High Power Channel–
type Reactor"–is a design that American physicist Hans Bethe has called "fundamentally faulty,
having a built–in instability." The RBMK design is now universally recognized as being defective,
although as of 2013 there are 11 RBMK reactors operating in Russia. The operators had switched
the safety systems off, and the reactor was being operated under improper and unstable conditions.
The accident occurred during an experiment scheduled to test a possible safety emergency core–
cooling feature. At 1:23 a.m. on April 26, extremely hot nuclear fuel rods were lowered into cooler
water, creating a giant amount of steam, which – because of the RBMK reactors ' design flaws –
created more reactivity in the nuclear core of reactor

The Disaster Preparedness Cycle Of Chernobyl
Chernobyl, in northern Ukraine and bordering Belarus, was one of the worst industrial disasters in
the world's history (Smith and Beresford, 2005). Even though the immediate effects were
catastrophic, the long–term effects have reached far, and continue to affect the area even today. The
history of the disaster, preparedness, and will be discussed, as well as the disaster preparedness
cycle. The disaster at Unit 4 at Chernobyl occurred at 0124 on April 26, 1986 (Smith and Beresford,
2005). At this time, there were four functional units for generating electricity, with two more being
built (Smith and Beresford, 2005). On April 25, these RBMK–1000 reactors were having supply
failure testing performed at the time of the disaster ... Show more content on Helpwriting.net ...
This happened due to a flaw in the RBMK design (Smith and Beresford, 2005). In most reactors, a
pending disaster would lead to the machine reducing its power, and avoiding this type of disaster
(Smith and Beresford, 2005). However, in this design of reactor, when water or steam is lost, power
levels rise, steam is created, and toxins can be released (Smith and Beresford, 2005). Thus, the
radiation from this explosion was spread in the air. After the explosion, first responders rushed in
with no comprehension of what they were exposing themselves to (Smith and Beresford, 2005).
During the immediate aftermath, the levels of radiation were not able to be measured, as no
equipment could measure that high (Smith and Beresford, 2005). Days after Chernobyl Unit 4 had
its explosion, the core was still burning (Smith and Beresford, 2005). Emergency employees
attempted to cool the core with sand, clay, and other materials, but it did not stop until ten days later
(Smith and Beresford, 2005). 134 of these workers had acute radiation illness, and 28 of these died
months later, with 20 cases having severe radiation illness (Smith and Beresford, 2005). Symptoms
included burns, sterility, and nausea; these were deterministic effects (Smith and Beresford, 2005).

Fukushima Chernobyl Disaster
The most recent major incident with nuclear power took place in Fukushima. Some people believe
that the explosion of nuclear reactor the tragedy is similar to the detonation of a thermal nuclear
device and this is a common misunderstanding: nuclear reactor cannot possibly explode in the way
atomic bomb does because the reactors utilize only slow neutrons. After the Chernobyl disaster, with
improvements in emergency procedures and plant designs, the fission process can now be
effectively moderated. When the Fukushima reactors were hit by the tsunami, the fission reaction
was shut off successfully. However, the real problem is that even if the fission process has been shut
off, the core still must be continuously cooled because the naturally

A Note on the Chernobyl Nuclear Disaster
The Chernobyl Nuclear Disaster: The Chernobyl Nuclear Disaster is an accident that took place at a
nuclear power plant in Ukraine in April 1986. The accident was because of a flawed Soviet reactor
design, severe mistakes by the plant operators, and direct result of Cold War isolation. As the
resultant steam explosion and fires emitted radioactive reactor core into the downwind and the
Earth's atmosphere, the accident was also attributed to the lack of any safety culture. The Chernobyl
Nuclear Disaster was a unique event because it's the only accident in commercial nuclear power
history in which radiation–related losses took place. Nonetheless, the design of the reactor is
exceptional and the disaster of minimal relevance to other elements of the nuclear industry.
Background on the Disaster: The Chernobyl Nuclear Power plant consisted of four nuclear reactors
with each of them capable of producing 1 gigawatt of electric power. During the time when the
disaster took place, these four reactors were producing approximately 10 percent of the electricity
used in Ukraine. The construction of this power plant started in the 1970s with the first reactor
commissioned in 1977 and the fourth in 1983. At the time when the disaster happened, the other two
nuclear reactors were still under construction (West par, 4). In April 1986, the operating crew
planned to evaluate whether the turbines of the fourth reactor could produce adequate energy to
maintain the running of the coolant

The Chernobyl Disaster And The Fukushima Nuclear Disaster
Uranium, which is the ninety–second element on the periodic table, is a very interesting element.
The radioactive uranium is used in atomic bombs. Also, people use it in what is called nuclear
power, an energy source that fourteen percent of the world uses. (NPR 3) In a nuclear power plant, a
process called fission that uses uranium is used to generate power. During fission, each uranium
atom is bombarded by neutrons, causing each uranium atom to turn into one atom of barium, one
atom of krypton, and three neutrons. These three neutrons bombard other uranium atoms, resulting
in more neutrons being produced and creating a chain reaction. Each time the uranium atom split,
energy is released. The leftover atoms are called nuclear waste. ... Show more content on

As I mentioned before, uranium is used in atomic bombs. So, uranium mines are very dangerous and
nuclear power is not safe. Right? I disagree. Uranium mines have created ways to reduce radiation
levels to their workers whenever they can and limits as how much radiation is allowed in a uranium
mine. Also, people have spent over forty years already creating safety regulations for uranium
mines. Finally, there is not enough uranium in a uranium mine for either of those to blow up like an
atomic bomb. (World Nuclear Association 4) As a result of these safety protections during uranium
mining, there has only been 371 deaths due to uranium mining contamination between 1950 and
2000, which is an average of around only 7.42 deaths per year. (Motherboard 2) In comparison, coal
mining had an average of 16 deaths per year in 2014. (MSHA

The Chernobyl Disasters In The Former Soviet Union
Chernobyl was one of the largest and most powerful nuclear reactors in the former Soviet Union. It
was used to power the part of the U.S.S.R now known as Ukraine. Also it was thought of as one of
the safest nuclear reactors in the world. But on April 26, 1986 something went terribly wrong and it
is now thought of as the worst nuclear disaster in history. It killed over 100,000 people with its
radiation and is still expected to contribute to the deaths of over 300,000 people. This disaster was
caused by a number of things including negligence. On April 25, 1986, the day before the accident a
test was scheduled to take place. This test was to see if the emergency systems would work properly
in case of power loss. At 1:00 am the Soviet made RBMK

The main reason for the mishap is by now well recognized (Petryna 1). However, initially the
Chernobyl catastrophe baffled the minds of people in the 20th century and definitely left the people
of Ukraine disordered while living in anxiety. Now, without question, the public knows that the
accident at Chernobyl was the result of a disastrous combination of ignorance from the Ukrainians
and complacency from the Soviets in control of Ukraine at the time. As according to American
physicist and Nobel laureate Hans Bethe, "...the Chernobyl disaster tells us about the deficiencies of
the Soviet political and administrative system rather than about problems with nuclear power." The
immediate basis of the Chernobyl accident was a mismanaged electrical–engineering experiment
(Rhodes "Chernobyl", PBS). While, the indirect source of the calamity was an industrial
malfunction of a Soviet made nuclear–based machine. Ironically, the Chernobyl accident occurred
during a test run, which was conducted to improve plant safety. This accident proved once more
what experienced control engineers have all learned: that a process must be understood before it can
be controlled. (Liptak "Control Global"). Engineers with no familiarity of reactor physics were
interested to see if they could draw electricity from the turbine generator of the Number 4 reactor
unit to run water pumps during an emergency, when the turbine was no longer being driven by the

In the wee hours of the morning of April 26, 1986, the town was still and operation of the power
plant was going smoothly. However, at 1:24 AM, 2 explosions suddenly tore through the fourth unit,
sending both debris and radioactive material flying through the air (IAEA, "One Decade After
Chernobyl: Summing Up The Consequences of The Accident." 67). The explosions that occurred
that night were not at all planned. They were the results of human error; an experiment conducted in
the fourth unit that had gone horribly wrong. During the conduction of the experiment, the power
was shut too rapidly and pressure began to build, rendering the unit unstable (Chernobyl Accident
1986). However, there were several other factors that also played a role in the explosions;
specifically, the different defects and flaws in the design of the Chernobyl nuclear power plant. The
plant in Chernobyl was an RBMK model, a military–based type of reactor. However, this model
suffered 3 major flaws in its design. Firstly, its cooling systems were made in such a way that
instead of reducing power when water or fuel becomes scarce, power would increase. The second
flaw would be in the control rods; they lacked the speed necessary to cope with changes in
reactivity. Lastly, it was lacking in proper containment systems to ensure safety within the unit
(Henares, jr., n.p.). There was also one flaw that was unique to this plant which may have led to its
demise:

What´s Chernobyl Disaster?
Question #13 Using a nuclear reactor is one way to produce non–natural occurring radioisotopes;
this can be done is through nuclear fission. Nuclear fission is the process of splitting a nucleus into 2
lighter nuclei. By doing this it releases energy and neutrons (Meyer, 2014). The energy from the
release is captured and converted into usable electric energy. However, there are some serious
dangers surrounding nuclear power for instance Chernobyl (Ukraine) in 1986, Three–mile–island
(Pennsylvania) in 1979, and Fukushima (Japan) in 2011. The Chernobyl disaster was a result of
human error, this accident resulted because proper protocols were not followed. The explosion
caused a partial meltdown which resulted in the release of radiation levels ranging from 10,000 –
300,000 mSv/hr (Meyer, 2014). The mishap that took place on Three–mile–island was the result of
an in–advert discharge to the soil and atmosphere (Meyer, 2014). Although the workers could stop
the release immediately, the damage was done. Dozens of fatalities occurred, and many lost their
lives subsequently due to acute exposure to the radiation. This ... Show more content on

The Three Mile Island accident happened on March 28th, 1979 near Middletown, Pennsylvania
(Vijayan, Kamble, Nayak, Vaze, and Sinha 2013). Ignorant workers, defects in the design of the
plant, and disastrous equipment were major components in the Three Mile Island disaster. Basically,
a valve erupted from too much pressure; this released just under 1,000,000 gallons of polluted water
into the basement of the plant. Only a small amount of radiation was leaked into the atmosphere, but
it was enough to scare people for years to come (Vijayan, Kamble, Nayak, Vaze, and Sinha 2013).
Only fractions of a millirem were found 50 miles away from the accident. A rem is a large dose of
radiation; a millirem is a thousandth of a rem (Edelson, 1986). This shows that there was not much
radiation that leaked into the atmosphere, unlike Chernobyl. In Sweden, they discovered numerous
millirems of radiation, which puts into perspective how big the Chernobyl disaster was. After the
Three Mile Island Accident, there were major changes including safety and defense–in–depth
improvements (Vijayan, Kamble, Nayak, Vaze, and Sinha 2013). The United States put forth major
changes in safety and technology for their nuclear power plants after the Three Mile Island accident,
but the Soviet Union did not believe this would happen in their plants. They believed they had no
flaws in their system and didn't want to add stronger safety features to their nuclear power plants to

Causes Of The Chernobyl Disaster
Have you ever helped someone out when they needed it? What caused the first explosion was that
there was faulty in the reactor. Is there a time you can remember someone had your back when you
didn't expect it? Nobody was alarmed that the explosion had happened and the soviet put many lives
in danger. The cause of Chernobyl is very sad because this should have never happened.
The cause of the explosion was from a faulty reactor in the power plant. The reactor was not stable
when it was in use. Right before the explosion had happened there had been a sudden power surge.
Also, a huge steam pressure increase that leads to a series of multiple explosions. The first explosion
was at 1:24 am. 5 out of the 12 people that were there had died because of the explosions that had
happened. When the explosion was released the makers of the reactor blamed it on Dyatlov because
it was his shift to work. Another thing that happened was that they say dyatlov messed up on a few
of safety precautions. The cooling system was switched off when the explosion had happened. The
turbine water pressure was at 0. The pressure was increasing when it should have been decreasing.
They also were running an experiment when it happened and it was in close down when it
happened. The explosion was equivalent to 10 bombs of Hiroshima. Dyatlov had received a fatal
amount of radiation. Dyatlov was sentenced to 10 years in prison for the cause of the explosion.
Although Dyatlov was sentenced 10 years he got out 18

Therefore, the test program was not formally coordinated with either the chief designer of the
reactor, nor with the scientific manager. Instead, it was approved only by the director of the plant.
According to the test parameters, at the start of the experiment, the thermal output of the reactor
should have been no lower than 700 MW. If the conditions of the reactor had been as planned, the
test almost certainly would have proceeded safely. The eventual disaster resulted from attempts to
boost the reactor output once the experiment had started, inconsistent with the approved procedure.
(Marples 39–43) The Chernobyl power plant had been in operation for two years without the
capability to ride through the first 60–75 seconds of a total loss of electric power. The station
managers wished to correct this at the first opportunity. This may explain why they continued the
test, even when serious problems arose, and why the requisite approval for the test was not sought
from the Soviet nuclear oversight regulator. (Gale 22–25) At 1:23:04 a.m. the experiment began, the
steam to the turbines was shut off, and a run down of the turbine generator began, together with the
four Main Circulating Pumps (MCP). The diesel generator started and sequentially picked up loads,
which was complete by 01:23:43; during this period the power for these four MCPs was supplied by
the coasting down turbine generator. As the momentum

The Chernobyl Disaster Of 1986 Essay
"Sometimes it takes a natural disaster to reveal a social disaster" (J.Wallis). A natural disaster can be
an environmental, technological, or human error. A natural disaster reveals a true society for how
they recover from such devastation. The true potential that we have in all of us to come together and
become stronger is astounding. After a disaster occurs, we want to learn what went wrong, how it
went wrong, who was involved, and if there was any rules broking. For that we can evolve our
society to become stronger. There have been many engineering disaster throughout the world. Some
engineering disasters include St. Francis Dam flooding, the Boston molasses disaster, and the 1970's
DC – 10 disasters. However, one of the most memorable disasters has to be the nuclear reactor
explosion in Chernobyl in Soviet Union. The Chernobyl disaster of 1986 is truly one of the worst
engineering disasters that have ever occurred. This explosion is the only level 7 on the International
Nuclear Event Scale and also the worst nuclear power plant accident to the day. This disaster
occurred due to human error because one of the workers decided to create his rules and not obey the
true procedure.
On April 26 1986, the fourth unit of 4 of the Chernobyl nuclear power plant was to close down for a
schedule maintenance check. During this operation, a test was decided to experiment the capability
of the equipment to establish enough power to operate the reactor core cooling system. This

The Cause And Effects Of The Chernobyl Disaster In 1986
Have you ever imagined the end of the Earth? Let's take the Chernobyl disaster in 1986 for example,
and look at how the explosion affected some parts of the world. Large areas were affected by the
Chernobyl explosion. Many things and properties were destroyed because of this. People, animals,
and plants were affected by the explosion and it made many suffer. It took many people to begin
cleaning up the mess, and they got sick. There is still a lot of damage there. It's very scary to know
that an accident like this could occur again. A large area was affected by the explosion of Chernobyl.
The bigger main areas that were really affected were Ukraine, parts of Russia, Europe, and Belarus.
Ukraine was where the Chernobyl power plant was located so that was the area that was really
affected. The gases spread to Russia, Europe and Belarus. It covered only most of Russia and
Ukraine. It wrecked over 63,000 square miles and was mostly located in rural areas. In Ukraine
there were gas exposures, devoured properties, and fire exposure. The fire exposure was what was
still burning after the explosion, and a lot was fires that affected people. There were a lot of lapland
animals dead from the outcome of the explosion, that were breathing in the gases and chemicals or
that got injured from the explosion who have died. The gas exposure is the toxic chemicals getting
outside in the air and the wind carries it around. Even if there is no wind, the chemicals are still
flowing around in

Nuclear Power And The Chernobyl Disaster
The Chernobyl Disaster was not meant to happen at all, what was supposed to happen was an
experiment to see if the reactor's own electrical needs could be supplied by a freewheeling turbine in
the event of a power outage, but the experiment did not go as it was planned. This experiment gone
wrong caused so much radiation sickness to the people, which lead to death by sickness, or death by
cancer. The people who lived ended up having children with many mutations and disabilities. The
Soviet Union wanted to hide the fact this never happened, so they released false information about
the disaster to the public not realizing the many after effects this would have on the world, the
people and the environment. Nuclear power plants may create a ... Show more content on

The first part of the five basic parts to a nuclear reactor starts with the core which holds the Uranium
fuel. As there are many different types of reactors each core holds a different type of Uranium. For
some examples, a heavy water reactor uses natural Uranium, which 0.7% is Uranium–235, while
light water reactors use Uranium that has been enriched, so that Uranium–235 makes up around 3–
5% of the total. The next part of the reactor is the moderator, now the moderator is a light material
such as water. The water will allow the neutrons to be slowed down without being captured. The
benefit of slowing down these fast neutrons during fission is it can increase their efficiency by
causing further fission. Control Rods are made up of materials that can absorb neutrons, such as
silver, boron, indium, hafnium, or cadmium. These are introduced into the reactor to reduce the
number of neutrons and thus stop the fission process when required to stop. Another use of the rods
is to control the level and distribution of power in the reactor. Next part of the reactor is the coolant.
The coolant is the fluid that circulates through the reactor core. This absorbs and transfers heat that
is produced by nuclear fission. Also at the same time, it maintains the temperature of the fuel within
the acceptable limits. The final part the nuclear reactor is the

drinking water and land around the area. According to the Energy Information Administration,
America's energy consumption in 2011 was thirteen times greater than it was in 1950. Currently,
there are at least 65 active nuclear plants that operate within 31 states. With energy usage increasing
at an alarming rate, the likelihood of a nuclear disaster occurring is a reality. It is important for

There is always risk involved when handling nuclear threats. Sometimes human error is to blame for
emergency shutdowns. On March 22, 1975, In Alabama, a massive fire took place at Browns Ferry
Nuclear reactor. The fire was caused by an electrical inspector's leaving a candle too close to foam
rubber while checking to see if the crew plugged the air leaks correctly within the cable room. The
fire spread quickly, causing the alarms to sounds and the reactor to fail. As a result of his actions, the
pressure system was destroyed, causing air to rush in the reactor, and the core was almost exposed.
Control rods were able to help shut the reactor down and fire extinguishers were used to control the
fire.
Major disasters can happen anywhere in the world. Further, intelligence sharing, freelance
journalists, and News networks, allows for the damage of isolated disasters to be viewed in every
country. Sensationalized incidents such as the Chernobyl disaster in Ukraine, highlights a systemic
failure within government due to its failure to regulate private companies. Public outcry from the
disaster prompts world leaders to make immediate changes within its emergency disaster guidelines.
During the Chernobyl disaster, Simple errors such as a Faulty structure design within the reactors,
mechanical failure in a cooling system or reduced air pressure, and human error created an
environment for a meltdown to occur. Without the proper emergency features,

Progress often drives society toward betterment as a whole and its importance is often emphasized
by those who wish to improve the lives of everyday citizens. However, the pursuit of progress can

lives. A clear example of the dangers of progress is evident when one takes a retrospective glance at
the Chernobyl nuclear plant disaster. Gerd Ludwig, a photographer interested in documenting the

The absence of students in a place in which children once visited as a part of their daily lives also
paints a bleak picture of the potential dangers of progress, and this is evident in the image. This
school library that was once regularly visited by children, teachers, and other individuals is now
uninhabitable due to the effects of the Chernobyl disaster. People are not present in the photograph,
and judging by the deteriorating state in which the school library exists, the building appears to have
been abandoned for quite some time. Instead of housing children who are in the pursuit of
knowledge, this place that was once a center of education for the Ukrainian youth now only holds
the weathered yellow pages of rotting books and fallen bookshelves. In addition to being devoid of
life, the objects of the library themselves depict a vacuum of human presence. For instance, there a
desk present in the photograph that is closer to the photographer than the bookcases, and this desk is
deteriorating and buried in books. This implies that the desk has not been used by a human being in
a very long time, since a student would need to clear the desk of books in order to easily make use
of it. Likewise, the layers of books littering the ground also suggest that the building is abandoned
for a lengthy period of time,

The Disaster Of The Chernobyl Nuclear Disaster
Engineering Disaster Newton's third law of motion states that for every action there is an equal and
opposite reaction; this law is not only applied in our studies but in our daily lives. For engineers, this
is a law to live by; reminding each engineer that each of his/her actions will have an equal
consequence whether it is good or bad. Engineers are trusted and respected individuals who
represent not only themselves but the profession as a whole; their title gives them a great
responsibility and a reputation to carry. On rare occasions do engineers make mistakes that
sometimes lead to disasters that impact the lives of many. For every disaster that occurs as a result
of an engineering mistake; thousands of lessons are learned. One disaster that impacted the lives of
many and was labelled as the worst engineering disaster in history is the Chernobyl nuclear disaster.
The chain of events that lead to this disaster where taken as lessons and used to write many of
today's engineering codes of ethics, and improve safety regulations in various industries.
On the morning of April 26th 1986 the world experienced the worst nuclear and engineering disaster
ever: the nuclear disaster of Chernobyl. Reactor number 4 at the Chernobyl nuclear power plant
exploded due various reasons: the design of the reactor itself had a major flaw that would make it
unstable when run at low power, and the employees responsible for running the reactor were
inadequately trained. Leonid Toptunov, the

The Economic Causes And Impacts Of The Chernobyl Disaster
The Chernobyl disaster, which happened just over 40 years ago, was the result of a single reactor
exploding after a multitude of errors led to the safety systems not being active. While not resulting
in massive losses of life, it has had serious economic impacts on countries like Ukraine and Belarus
and serious impacts on health and immune systems in the contaminated areas. Both of these factors
are especially true for people who are poor or impoverished. Poverty is an important issue in
disaster research because it is a widespread phenomenon with powerful effects. Poverty often
coincides with other types of vulnerable populations, so addressing its effects of poverty is a strong
first step in addressing the vulnerabilities of other groups. Poverty also impacts the way people live
before, during, and after disaster, so it has wider applications that solely on disaster research.
Summary: Chernobyl
At 1:23 AM on April 26, 1986, a safety test that should have been routine ended in disaster (Rybar,
Vickery). The Chernobyl plant, "poorly built" by the Soviet Union, faced such quick destruction that
two hours later, some employees still had no idea what had happened (Rybar).
For 83 minutes, reactor number 4 exploded, sparking the first disaster of its kind in the history of
mankind (Rybar). The blaze would last for ten days, making it essentially impossible for anyone to
enter the plant in order to slow or stop the amount of radioactive materials the were leaking into the

Comparing The Fukushima And The Chernobyl Disasters
The Fukushima and the Chernobyl Disasters
Both the Fukushima Daiichi nuclear accident of 2011 and the Chernobyl nuclear accident of 1986
were both rated seven according to the International Nuclear and Radiological Event Scale.
However, the two nuclear accidents differed in terms of their cause, the response from the
government and health effects.
Key facts about both accidents
The Chernobyl accident caused by a flawed reactor design which was being operated by
inadequately trained people. The steam explosion that resulted from the accident released more than
5% radioactive reactor downwind into the atmosphere. Two employees died instantly at the site
while 28 others died a few weeks later as a result of radiation poisoning (Balonov, 2006). In
Fukushima, the accident was caused by the earthquake and tsunami that hit the plant. Fukushima
power station was worst hit by the earthquake and tsunami destroying the backup power, building
facility and the external nuclear power supply. The following morning, after the accident had
occurred, radioactive materials were found scattered in the environment. ... Show more content on

The government also supplied the people near Fukushima with potassium iodide as protect their
thyroid glands from absorbing radiation. The preventive measures undertaken by the Japanese
government limited severe health effects that could have resulted from the accident (World Health
Organization, 2013). In contrast, the former Soviet authority was slow to respond after the
Chernobyl accident. There was no rapid reaction to supply the residents near the area with milk and
food, which resulted in the rise of thyroid among the children and the adolescents who had

The power plant was built next to the city of Pripyat, which had a population of fifty thousand
people in 1986 (World Nuclear Association). "The Chernobyl plant used four Soviet–designed
RBMK–1000 nuclear reactors– a design that is now universally recognized as incoherently flawed"
says Lallanilla,"In most nuclear reactors, where water is used as a coolant and to moderate the
reactivity of the nuclear core, as the core heats up and produces more steam, the increase in steam
bubbles or 'voids' in the water reduces the reactivity in the nuclear core. This is an important safety
feature found in most reactors built in the United States and other Western nations." Irresponsibly,
"operators disabled the plant equipment including automatic shutdown mechanisms the day before
the disaster when they were to perform routine maintenance on reactor number four" says sources
from the U.N. Scientific Committee on the effects of Atomic Radiation (Lallanilla). Recorded at
1:23 on April 26, extremely hot nuclear fuel rods were disengaged into cooling water. This created a
large amount of steam that exceeded the reactivity in the nuclear core of reactor number four. This
power surge caused an "immense explosion that detached the one thousand ton plate that was
covering the reactor's core" (Lallanilla). Thus, releasing radiation into the atmosphere and cutting
off the flow of

The pressure from the nuclear arms race affected both the US and USSR causing them to
miscalculate their nuclear reactor designs. In March 28, 1979, the US endured one of their biggest
nuclear power plant accidents in US history, Three Mile Island. The accident that occurred in
Middletown, Pennsylvania, was the result of a malfunction in Unit 2 reactor's cooling system. After
this event, the US realized that they needed to strengthen regulations and improve the safety of
nuclear energy. Unlike the US, the Soviet Union was more focused on passing up their opponent
rather than focusing on the safety of nuclear energy. In 1970, the Soviet Union started to build a
nuclear power plant 80 miles north of Kiev, Ukraine in a town called Chernobyl. After the launch of
Chernobyl, 3 km away, a new town called Pripyat was built to house the employees who operated
the new power plant. Sixteen years later, as Chernobyl was midway through of constructing their 5th
reactor, the 4th reactor endured an explosion which led to the spread of large amounts of radiation
into the atmosphere as a result of poorly engineered designs. The Soviet Union used an unusual
designed reactor called, RBMK also known as LWGR (Light Water Graphite Reactor). The Soviet–
designed RBMK (reaktor bolshoy moshchnosty kanalny, high–power channel reactor) was a
pressurized water–cooled reactor with individual fuel channels and used

Safety-Culture Background and Concept: The Chernobyl...
Introduction
Great strides towards a safe workplace environment have been made in the construction industry.
Hinze (1997) assume that the written safety plans have the potential to be very effective, but
companies ought to go ahead of the safety plan and build a suitable "safety culture". The
construction industry offers a thrilling and dynamic atmosphere. The flow of exclusive projects, the
on–site operational environment, and the inventiveness and innovation required to solve one–off
troubles require a creative approach to work which is seldom found elsewhere. The problem of
safety culture – What is it and how do you become one? – is probably the main issue in modern
thinking about safety (Turner and Pidgeon, 1997). Most attention has been paid to the issue of safety
climate (Zohar, 1980), a concept easier to measure, but the underlying expectation is that the best
and safest organizations have a safety culture, and safety climate which is an indirect measure of
how close an organisation approximates to that.
Safety–Culture Background& Concept
The emergence of safety culture came after the 1986 Chernobyl nuclear power plant accident which
triggered the fusion of the two concepts, safety and culture. This event applied an approach about
looking beyond immediate engineering and technical failures and brought into focus the
performance of 'the person', designing, managing, constructing or operating risky facilities. Only
then, the psychology of 'why people behave as they

Chernobyl: The Design of Disaster Essay
The recent nuclear disaster in Japan has resurrected the memories of Chernobyl in the public's
imagination. The 1986 disaster of the Ukrainian reactor at the Chernobyl nuclear power plant is still
regarded as the worst nuclear disaster in history, although the Japanese crisis is still unfolding. The
Chernobyl disaster "was the product of a flawed Soviet reactor design coupled with serious mistakes
made by the plant operators. It was a direct consequence of Cold War isolation and the resulting lack
of any safety culture" ("Chernobyl," WNA, 2011). In 1987 an important article appeared in the
Journal of the American Medical Association. The author, Roger E. Linnemann, MD, had this to say
about the accident:

During the test the operators had also disabled automatic shutdown mechanisms.
The crew unintentionally let steam voids form in the reactor's cooling water as it passed through the
core. One of the flaws of the reactor design was its tendency to generate a sudden and uncontrollable
burst of power if large steam voids are allowed to form in the reactor core, as happened during the
test (Gillette 1986). In addition to the documented problem of the steam voids inherent in the design,
poor manual operation of the reactor had caused the reactor to be in an even more unstable state than
usual.
As the fission accelerated, the reactor's heat output rose 330 million watts within three seconds. This
triggered explosions of steam and hydrogen gas in the core that destroyed the reactor, blew the roof
off the building, and started a graphite fire in the core that spewed radioactive wastes into the
atmosphere for the next 11 days. (Gillette 1986) After the dramatic power surge occurred, and the
ensuing steam and hydrogen explosion that destroyed the reactor core and killed several workers,
there was a second explosion. This caused the graphite moderator to burst into flames, which was
the main cause of the release of radioactivity into the environment (Kubiszewski & Cleveland
2009). According to Freedom for Fussion Organization, the lack of a steel reinforcement concrete

Nuclear Power : A Case Study On The 1986 Disaster At The...
Introduction
Nuclear power plays a hugely important role in the generation of today's world's everyday energy
needs. Accounting for around 11% of the world's energy needs, nuclear energy is generally
harnessed using uranium as the fuel [1]. Within a nuclear reactor, a neutron collides with a uranium
nucleus to induce a chain fission reaction. This is a reaction in which the nucleus of an atom splits to
form two separate atoms, with a great quantity of energy being released in the process [2]. This heat
energy is absorbed by water or carbon dioxide gas which is pumped through the reactor and later is
used to heat water converting it to steam. The steam then rotates turbines in order to produce
electricity. This report will explore the ... Show more content on Helpwriting.net ...
Production of nuclear power leads to lower energy costs and provides jobs for thousands of people.
In contrast to the advantages of nuclear power, listed below are some of the major disadvantages:
Nuclear power produces large amounts of toxic waste which can be harmful to the environment.
Greenhouse gases are still produced in other ways, contributing to climate change.
The consequences of a nuclear accident are potentially very damaging to human life, health and the
environment.
Case–Study: The 1986 Accident at the Chernobyl Nuclear Power Station
The Chernobyl Nuclear Power Station is located approximately 3.6 kilometres from the city of
Pripyat in the Soviet Union (now part of Ukraine, close to the border with Belarus) [4]. The power
station was the site of four completed nuclear reactors, as well as two further reactors under
construction. In the early hours of the 26th of April 1986, Reactor 4, which had been running for
approximately 2 years prior, was undergoing maintenance checks in order to review emergency
procedures [5]. In a test to examine whether the cooling pump system could function in the event of
the failure of the auxiliary electricity supply, too many control rods were lowered, causing a near–
complete shutdown of the reactor. Engineers raised the rods in an attempt to restart the system, but
raised too many rods, resulting in a great increase in power output. At 1.23am, the emergency

thick concrete walls were bent like rubber. I thought war had broken out. We started to look for
Khodemchuk (his coworker) but he had been by the pumps and had been vaporized. Steam wrapped
around everything; it was dark and there was a horrible hissing noise. There was no ceiling, only
sky; a sky full of stars." A stream of ionizing radiation was shooting star wards, like a laser beam. "I
remember thinking how beautiful it was."
This quote, which I obtained from the newspaper The Guardian's website, is from Sasha Yuvchenko,
a former employee at the Chernobyl nuclear power plant. What he didn't know at the time of the

The Failure Of The Chernobyl Nuclear Disaster Essay
Executive Summary Thomas J. Watson once said, "go ahead and make mistakes. Make all you can,
because that 's where you will find success: on the far side of failure." Making mistakes or failures
are a part of life, as Watson puts it, it is vital to make mistakes and learn from them. Making
mistakes is an integral part of innovation. It is the ability to overcome these faults; faults allow
humans to grow and expand on the knowledge of the unknown so that in the future we are well
prepared for the unexpected. By understanding from previous failures, it stimulates innovation, new
ways to approach and triumph over obstacles. The purpose of this report is to highlight significant
engineer failures over history. Many of the disasters occurred in the latter half of the 20th and
beginning of the 21st century. Starting with the Chernobyl nuclear disaster, three aerospace related
accidents, Challenger, Apollo 13, and Mars Climate Orbiter. As well as the radiation machine,
Therac–25, and the more recent Deepwater Horizon oil spill. Each of the topics will go in–depth on
background information, how the incident occurred, way it could have been prevented, and future
implications, or measures taken due to these accidents to avoid future disasters. Nothing is perfect,
everything has flaws, this includes processes and people. There is not a final approach to solve
problems. Mistakes do not discriminate; it happens at some point in one's life. One of the most
critical take on mistakes is
