Fukushima nuclear disaster
The 2011 Fukushima nuclear disaster in Japan was caused by an earthquake and tsunami that damaged nuclear power plants and disabled their cooling systems. This led to reactor meltdowns and explosions, releasing radiation into the local environment. Over 170,000 people were displaced, and radiation spread through air and water. Solutions implemented at the plant included new automated cooling systems and filters to reduce radiation releases. The disaster increased opposition to nuclear power internationally and concerns about the health impacts on people and environment from radiation exposure.
Fukushima Daiichi nuclear disaster
An earthquake and tsunami on March 11, 2011 disabled the power and cooling systems of three reactors at the Fukushima Daiichi Nuclear Power Plant in Japan, causing a nuclear accident. Hydrogen explosions occurred at reactors 1 and 3, and an explosion due to rising pressure happened at reactor 2. By March 16th, 50% of the plant was on fire. The disaster, rated a 7 on the International Nuclear Event Scale, resulted in high radioactive release and economic losses of 150 billion euros for Japan, while increasing cancer risks and damaging the surrounding environment.
Fukushima Nuclear Disaster in Japan.pptx
The Fukushima nuclear disaster was caused by an earthquake and tsunami in March 2011 that disabled the cooling systems at the Fukushima Daiichi Nuclear Power Plant in Japan. This led to nuclear meltdowns in three reactors and the release of radioactive materials into the environment. While radiation exposures were generally low and no health effects were observed in the public, some emergency workers received doses exceeding limits. The disaster caused widespread infrastructure damage and led to the long-term evacuation of residents within 20 km of the plant due to ongoing radiation risks.
Fukushima nuclear disaster in japan
The Fukushima nuclear disaster was caused by an earthquake and tsunami in March 2011 that knocked out power to the plant. Three reactors suffered core damage and released radiation. Over 18,000 people died from the natural disasters. The accident exposed over 170 emergency workers and 6 workers to radiation above limits. Decommissioning of the damaged reactors is expected to take 30-40 years. Key lessons included the need for stronger safety measures and emergency response plans for earthquakes and tsunamis.

2) The system uses cloud computing and mobile phones to process and transfer data quickly to model the wind-driven spread of radioactive contamination.
3) Mathematical models of pollution rates, emission rates, wind speeds, and other atmospheric factors are used to predict the contaminated areas and radioactive concentrations for fast emergency response.
Fukushima daichi disaster
The 2011 Tōhoku earthquake and tsunami caused a nuclear accident at the Fukushima Daiichi Nuclear Power Plant. The 9.0 magnitude earthquake damaged the plant but backup diesel generators provided power for cooling. However, a 14 meter tsunami then flooded the generators, causing a complete loss of power and cooling capability. This led to three nuclear meltdowns, hydrogen-air explosions, and the release of radioactive material into the environment, forcing the evacuation of over 80,000 people within a 20km radius. The accident occurred due to inadequate safety provisions against earthquakes and tsunamis at the plant despite known risks and recommendations for upgrades.

Fukushima disaster cameron and cooper
An earthquake and tsunami on March 11, 2011 caused a meltdown at the Fukushima Daiichi Nuclear Power Plant in Japan. Reactors 1-3 experienced full meltdowns after their cooling systems failed when the tsunami flooded backup generators. The explosions and radiation releases from the plant required the evacuation of over 100,000 people and contaminated the surrounding area. Long term impacts include increased cancer risks and the displacement of residents, as the plant will take decades to fully decontaminate and decommission.
Nuclear accidents
This document describes nuclear accidents and incidents on the International Nuclear Event Scale (INES). It explains:
1) The INES scale ranges from Level 0 events with no safety impact to Level 7 major accidents with widespread health and environmental effects. Level 7 events include Chernobyl and Fukushima.
2) Nuclear accidents can occur at nuclear plants or other nuclear facilities and result in inadvertent releases of radioactivity. Their severity depends on impacts to people, the environment and nuclear safety barriers.
3) Accidental exposure to radiation above certain levels can cause health effects like nausea, fever, and increased risk of cancer or death depending on the received dose.
Nuclear disasters
Nuclear disasters can occur as a result of accidents at nuclear power plants or from meltdowns. The three major nuclear disasters were at Three Mile Island in 1979, Chernobyl in 1986, and Fukushima in 2011. Nuclear disasters can cause widespread health and environmental damage through the release of radiation. Proper safety systems and emergency response plans are needed to minimize damage and risk from nuclear disasters.

It discusses the causes of the incident being an earthquake and subsequent tsunami, the damage to the reactors, and the release of radiation into the environment. It also examines the health effects on local populations, including increased cases of thyroid cancer in children, and measures taken since then to improve nuclear safety, such as installing backup power sources and coastal barriers.
Chernobyl Nuclear Powerplant Disaster
Here is the powerpoint presentation about the nuclear disaster at the chernobyl Nuclear Powerplant in detail.
Chernobyl Nuclear Power Plant Disaster
The Chernobyl disaster was a nuclear reactor accident that occurred on April 26, 1986 at the Chernobyl Nuclear Power Plant in Ukraine. It was the worst nuclear power plant disaster in history and released radioactive material into the atmosphere that spread over much of the western USSR and Europe. Over 300,000 people were evacuated from the contaminated areas in the aftermath. The disaster occurred when a reactor exploded during a safety test, which caused several explosions and a fire that released high levels of radiation and scattered radioactive debris over 2,000 square miles.
nuclear disasters
A nuclear disaster can occur through events like a meltdown at a nuclear reactor plant. This can result in massive amounts of radiation and radioactive material being released into the environment, contaminating the area for hundreds of years. A meltdown happens when the reactor core gets so hot that the nuclear fuel rods and surrounding steel melt. This molten material can sink into the ground and react with water, causing explosions that spread radioactive debris over wide areas. While nuclear power can provide energy, accidents can cause widespread and long-lasting contamination of both the environment and human populations through radiation exposure. Effective prevention and safety measures are necessary to minimize these risks.
Geography: Nuclear Disaster
A nuclear accident is defined as an event involving significant radioactive release or reactor core melt. Examples include Chernobyl and Fukushima disasters where earthquakes and tsunamis disabled cooling systems, causing reactor cores to melt. This can release massive amounts of radiation into the environment for hundreds of years. During a meltdown, the extreme heat causes reactor fuel to melt through containment and react with groundwater, potentially causing large radioactive steam explosions. Proper cooling systems are needed to safely control reactor heat and prevent meltdowns.
Technological disaster
An oil rig drilling into a salt mine caused a technological disaster at Lake Peigneur in Louisiana in 1980. The drill punctured the roof of the mine, draining the freshwater lake into the hole and dissolving the salt deposits underground. The resulting whirlpool sucked in the rig, barges, and surrounding land. Over a decade later, the Chernobyl disaster in 1986 was the worst nuclear power plant accident in history when a failed safety test led to explosions and fires that released radioactive contamination across Europe.

Nuclear catastrophe
The document summarizes two major nuclear disasters: Chernobyl in 1986 and Fukushima Daiichi in 2011. Chernobyl was caused by operator error and reactor design flaws, exposing many to radiation and increasing cancer rates. Fukushima was triggered by an earthquake and tsunami damaging the plant and backup generators, causing meltdowns and radiation leaks. Both incidents had massive health, economic and psychological impacts through radiation exposure, evacuation, land contamination and food restrictions. Ongoing efforts focus on containment, monitoring and decontamination to cope with the aftermath.
Disaster in Chernobyl
On April 26, 1986, a reactor explosion at the Chernobyl nuclear power plant in Ukraine released 190 tons of radioactive gases into the atmosphere. The explosion was caused by operator errors during a test. It resulted in a fire that lasted 10 days and spread radiation over much of Europe. Over 7 million people lived in contaminated areas, with thousands dying or suffering long-term health effects from radiation exposure in the following decades. The disaster highlighted issues with the design of the RBMK nuclear reactors and poor safety procedures.

This chapter describes what is probably the best example historically of what has come to be known as a "cascading crisis": earthquake, tsunami, with secondary nuclear reactor damage. http://www.jblearning.com/catalog/9781449645199/DOC-20240315-WA0003..pdf FUKUSHIMA NUCLEAR
The 2011 Fukushima Daiichi nuclear disaster in Japan was caused by an 9.0 magnitude earthquake and subsequent tsunami that struck the area on March 11, 2011. The tsunami disabled the power supply and cooling systems at three nuclear reactors, causing meltdowns. Hydrogen explosions at three reactor units caused additional radiation leaks. The accident released radioactive substances into the local environment and forced the long-term evacuation of over 100,000 people from a 30 km exclusion zone around the plant due to high radiation levels. The consequences of the disaster included health effects from radiation exposure, economic costs of over 150 billion euros, and long-term environmental contamination.
Japan Earthquake, Tsunami and Radiation Event 2011
The 2011 Tohoku earthquake and tsunami caused widespread damage in Japan. The 9.0 magnitude earthquake struck off the coast of Honshu on March 11, 2011 and generated a powerful tsunami. Over 15,000 people were killed and over 6 million homes lost power. The tsunami also caused a nuclear accident at the Fukushima Daiichi power plant, resulting in radioactive releases and over 100,000 evacuations. The Japanese government coordinated relief efforts and long-term responses such as waste disposal to address the extensive damage from the earthquake, tsunami and nuclear incidents.

Japan Earthquake and Tsunami by Justin Formosa, 3.04
The 2011 Tōhoku earthquake was a 9.0 magnitude earthquake off the coast of Japan that triggered extremely destructive tsunami waves up to 38 meters tall. Over 15,000 people were killed and over 125,000 buildings were damaged or destroyed by the earthquake and tsunami in Japan. It also caused nuclear accidents at several power plants, most seriously at the Fukushima I Nuclear Power Plant where residents within a 20 km radius had to evacuate. It was the most expensive natural disaster on record, with damage estimated at over $300 billion.
The think quest project
Nuclear reactors carry risks of accidents and radiation exposure that can harm human health and the environment. Major accidents like Chernobyl and Fukushima have caused widespread contamination and required large evacuations. While nuclear waste is small in volume compared to fossil fuels, it remains highly radioactive for extremely long periods and requires careful disposal. New reactor designs aim to reduce risks through passive safety systems and using alternative fuels like uranium-238 that produce less long-lived waste. Public education about radiation risks and emergency plans is also important to prevent overreaction during accidents.

This document discusses nuclear energy. It provides a brief history of nuclear energy, explaining how nuclear fission and fusion work to produce energy. Nuclear fission in power plants generates electricity by splitting heavy radioactive elements like uranium and producing heat. Nuclear fusion combines light elements and occurs inside the sun. While nuclear energy has advantages like low emissions, disadvantages include high costs and long-term radioactive waste storage needs. The document examines applications and environmental impacts of nuclear energy.
Japan tsunami
The 2011 Tōhoku earthquake and tsunami in Japan caused widespread damage. A magnitude 9 earthquake triggered a massive tsunami, with waves over 128 feet high in some areas. Over 15,000 people were killed or declared missing. The tsunami also caused a nuclear meltdown at the Fukushima Daiichi Nuclear Power Plant. Recovery continues years later, with debris removal, rebuilding of infrastructure, and relocation of evacuees from Fukushima. The earthquake and tsunami had effects across the Pacific region and around the world.

Chernobyl_Disaster.pptx
The Chernobyl disaster was the worst manmade disaster in history. It occurred in 1986 at the Chernobyl nuclear power plant in Ukraine when operator errors caused a reactor explosion. This released 190 tons of radioactive material into the atmosphere and started fires that burned for 10 days. Over 30 people died shortly after from acute radiation poisoning, while thousands more developed long-term illnesses like cancer. The radioactive cloud spread across Europe, contaminating wide areas and increasing health issues for millions of people exposed. While efforts were made to contain the reactor, the cement shell surrounding it is deteriorating and in need of replacement.
Untitled
The document discusses the Fukushima Daiichi nuclear disaster and perspectives on nuclear power. It provides background on the mechanics of nuclear fission used for power generation. While nuclear power doesn't emit greenhouse gases, it carries risks of radiation leaks from accidents or attacks. Major concerns include limited nuclear fuel resources, difficulties disposing of radioactive waste, and nuclear power plants' vulnerability to disasters or terrorism.
2011 Tōhoku Earthquake and Tsunami in Japan
The 2011 Tōhoku earthquake and tsunami caused widespread damage in Japan. A 9.0 magnitude earthquake struck off the coast of Japan, generating massive tsunamis up to 40 meters high. Over 15,000 people were killed and infrastructure like roads, railways and power plants were severely damaged. The tsunamis also caused a nuclear accident at the Fukushima Daiichi Nuclear Power Plant, resulting in radiation leaks. The disaster caused short term impacts like power outages and interruptions to transportation and communications across northern Japan.
Environmental catastrophe
The document discusses the history of nuclear accidents and their effects over three nuclear ages:
1) The first nuclear age from 1938-1967 saw the atomic bombings of Hiroshima and Nagasaki that killed over 200,000 people and caused long-term health effects.
2) The second nuclear age from 1967-1992 was marked by the Chernobyl disaster, where a power plant explosion released radiation over 350 times the bomb dropped on Hiroshima. The area remains largely uninhabited.
3) The third nuclear age from 1992-2011 saw the Fukushima disaster where an earthquake caused nuclear meltdowns. Residents were evacuated and food bans put in place due to nuclear contamination.
The power of mother nature
This document discusses several natural disasters including earthquakes, avalanches, tsunamis, volcanoes, and tornadoes. It provides details on the causes and effects of each disaster. For earthquakes, it notes they are mostly caused by faults rupturing and details the relative energy levels of different magnitude quakes. For tsunamis, it explains they are caused by displacement of large water volumes, and discusses the devastating 2004 Indian Ocean and 2011 Japan tsunamis. It also summarizes information on avalanches occurring from increased snow loads, and describes volcanoes as ruptures allowing underground gases and lava to escape.
Bad work, Tsunami in Japan
A massive 8.9 magnitude earthquake triggered a tsunami off the coast of Japan that washed away homes and cars. The tsunami hit Hawaii and west coast of the United States, causing widespread damage across Japan's northeast coast. The earthquake shortened Earth's day by 1.8 microseconds and increased its axial wobble. It also shifted parts of Japan by up to 13 feet. The Japanese government declared it the worst crisis since World War II due to power outages and loss of telecommunications across affected areas.
2011 Tohoku Earthquake and Tsunami Japan
This document provides information about earthquakes and tsunamis in Japan. It begins with an introduction to Japan's geography and location within the Pacific Ring of Fire. It then discusses Japan's history of earthquakes, including a major 9.0 magnitude earthquake in 2011 that caused over 15,000 deaths and US$235 billion in damages. The earthquake generated a large tsunami that flooded coastal areas. The short and long term impacts included widespread damage, deaths, injuries, power outages, and environmental effects. The response involved immediate search and rescue efforts, temporary shelters and hospitals, and rebuilding infrastructure over subsequent years through large public works projects.
Good work
A massive 8.9 magnitude earthquake struck off the coast of Japan, triggering a devastating tsunami. The tsunami waves reached heights of over 130 feet in some areas, washing away homes, cars, and devastating many entire towns in Japan's northeastern coast. The earthquake and tsunami also caused a nuclear crisis at the Fukushima Daiichi nuclear power plant, as damage to the plant's cooling system from the tsunami threatened a potential meltdown. Authorities worked to avert a catastrophic meltdown by cooling the reactors. The disaster is considered Japan's worst crisis since World War II.

Kinetic studies on malachite green dye adsorption from aqueous solutions by A...Open Access Research Paper
Water polluted by dyestuffs compounds is a global threat to health and the environment; accordingly, we prepared a green novel sorbent chemical and Physical system from an algae, chitosan and chitosan nanoparticle and impregnated with algae with chitosan nanocomposite for the sorption of Malachite green dye from water. The algae with chitosan nanocomposite by a simple method and used as a recyclable and effective adsorbent for the removal of malachite green dye from aqueous solutions. Algae, chitosan, chitosan nanoparticle and algae with chitosan nanocomposite were characterized using different physicochemical methods. The functional groups and chemical compounds found in algae, chitosan, chitosan algae, chitosan nanoparticle, and chitosan nanoparticle with algae were identified using FTIR, SEM, and TGADTA/DTG techniques. The optimal adsorption conditions, different dosages, pH and Temperature the amount of algae with chitosan nanocomposite were determined. At optimized conditions and the batch equilibrium studies more than 99% of the dye was removed. The adsorption process data matched well kinetics showed that the reaction order for dye varied with pseudo-first order and pseudo-second order. Furthermore, the maximum adsorption capacity of the algae with chitosan nanocomposite toward malachite green dye reached as high as 15.5mg/g, respectively. Finally, multiple times reusing of algae with chitosan nanocomposite and removing dye from a real wastewater has made it a promising and attractive option for further practical applications.

Improving the viability of probiotics by encapsulation methods for developmen...Open Access Research Paper
The popularity of functional foods among scientists and common people has been increasing day by day. Awareness and modernization make the consumer think better regarding food and nutrition. Now a day’s individual knows very well about the relation between food consumption and disease prevalence. Humans have a diversity of microbes in the gut that together form the gut microflora. Probiotics are the health-promoting live microbial cells improve host health through gut and brain connection and fighting against harmful bacteria. Bifidobacterium and Lactobacillus are the two bacterial genera which are considered to be probiotic. These good bacteria are facing challenges of viability. There are so many factors such as sensitivity to heat, pH, acidity, osmotic effect, mechanical shear, chemical components, freezing and storage time as well which affects the viability of probiotics in the dairy food matrix as well as in the gut. Multiple efforts have been done in the past and ongoing in present for these beneficial microbial population stability until their destination in the gut. One of a useful technique known as microencapsulation makes the probiotic effective in the diversified conditions and maintain these microbe’s community to the optimum level for achieving targeted benefits. Dairy products are found to be an ideal vehicle for probiotic incorporation. It has been seen that the encapsulated microbial cells show higher viability than the free cells in different processing and storage conditions as well as against bile salts in the gut. They make the food functional when incorporated, without affecting the product sensory characteristics.

Optimizing Post Remediation Groundwater Performance with Enhanced Microbiolog...
Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system.
Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.

The incorporation of a 3DCSM and completion of HRSC provided a tool for enhanced, data-driven, decisions to support a change in remediation closure strategies. Currently, an approved pilot study has been obtained to shut-down the remediation systems (ISCO, P&T) and conduct a hydraulic study under non-pumping conditions. A separate micro-biological bench scale treatability study was competed that yielded positive results for an emerging innovative technology. As a result, a field pilot study has commenced with results expected in nine-twelve months. With the results of the hydraulic study, field pilot studies and an updated risk assessment leading site monitoring optimization cost lifecycle savings upwards of $15MM towards an alternatively evolved best available technology remediation closure strategy.

Microbial characterisation and identification, and potability of River Kuywa ...Open Access Research Paper
Water contamination is one of the major causes of water borne diseases worldwide. In Kenya, approximately 43% of people lack access to potable water due to human contamination. River Kuywa water is currently experiencing contamination due to human activities. Its water is widely used for domestic, agricultural, industrial and recreational purposes. This study aimed at characterizing bacteria and fungi in river Kuywa water. Water samples were randomly collected from four sites of the river: site A (Matisi), site B (Ngwelo), site C (Nzoia water pump) and site D (Chalicha), during the dry season (January-March 2018) and wet season (April-July 2018) and were transported to Maseno University Microbiology and plant pathology laboratory for analysis. The characterization and identification of bacteria and fungi were carried out using standard microbiological techniques. Nine bacterial genera and three fungi were identified from Kuywa river water. Clostridium spp., Staphylococcus spp., Enterobacter spp., Streptococcus spp., E. coli, Klebsiella spp., Shigella spp., Proteus spp. and Salmonella spp. Fungi were Fusarium oxysporum, Aspergillus flavus complex and Penicillium species. Wet season recorded highest bacterial and fungal counts (6.61-7.66 and 3.83-6.75cfu/ml) respectively. The results indicated that the river Kuywa water is polluted and therefore unsafe for human consumption before treatment. It is therefore recommended that the communities to ensure that they boil water especially for drinking.

- 1. FUKUSHIMA DISASTER Anik Chandel (Department of Environmental Science)
- 2. INTRODUCTION • It is the second biggest nuclear disaster in the world after CHERNOBYL disaster. • It is assessed at level 7 – the maximum scale value on the International Nuclear Event Scale (INES) • Earthquake followed by tsunami and nuclear disaster arose with in 5 hours.
- 3. FUKUSHIMA DISASTER Location : Fukushima , Japan Date : 11th March, 2011 Type : Nuclear disaster Causes : Tsunami followed by earthquake
- 4. Fukushima accident • Fukushima accident, also called Fukushima nuclear accident or Fukushima Daiichi nuclear accident, accident in 2011 at the Fukushima Daiichi (“Number One”) plant in northern Japan, the second worst nuclear accident in the history of nuclear power generation. The facility, operated by the Tokyo Electric and Power Company (TEPCO), was made up of six boiling- water reactors constructed between 1971 and 1979. At the time of the accident, only reactors 1–3 were operational, and reactor 4 served as temporary storage for spent fuel rods.
- 5. Fukushima Daiichi Nuclear Plant • It is one of the 15th largest nuclear power station in the world. • It was the first nuclear power plant to be designed , constructed and run by the general electric and Tokyo Electric Power Company (TEPCO) • After the disaster on 11 march , 2011 the plant is disable for avoiding further radioactive decay
- 6. INCIDENT • The nuclear disaster took place with a series of disaster. • Over 15800 people died from the combined effects of the events • Over 20 km area around the nuclear plant was evacuated by the government. • It occurred due to equipment failure by tremors causing core meltdown and relase of radioactive material.
- 7. THE ACCIDENT • Fukushima Daiichi Nuclear Disaster was on energy accident , initiated primarily by the tsunami and earthquakes on march 11, 2011
- 8. What happened ? Friday march 11th @ 2.36 pm local Magnitude 9.0 earthquake hits the pacific , 231 miles northeast of Tokyo. It is the 4th biggest earthquake in the world since 1990. Generated a 14m tsunami waves
- 9. AS A RESULT: Earthquake Earthquake caused automatic Shutdown of 3 operating units. Offsite power lost 14m Tsunami ( less than 1hr later) All emergency Back up power lost 8-10 hr later Station Batteries wear out
- 10. • Earthquake and tsunami disable the power supply and cooling of three reactor , causing nuclear accident. • The accident was rated 7 on the INES scale , due to high radioactive release over a day
- 11. causes Earthquake Tsunami The earthquake was caused by the rupture of a stretch of the subduction zone associated with the Japan Trench, which separates the Eurasian Plate from the subducting Pacific Plate A magnitude 9.0 earthquake strikes off the coast at 2:46 p.m., triggering a towering tsunami that reaches land within half an hour. The tsunami smashes into the Fukushima Daiichi nuclear plant, destroying its power and cooling systems and triggering meltdowns at three reactors.
- 12. Effects • Impact on people: 1,70,000 people are displaced Higher risk of cancer. Greatest impact on psychological. Due to release radioactive substances cancer was spreading
- 13. • Impact on social life Home which are located 30km around of fukushima have been evacuated.
- 14. • Impact on economic After the accident Japan losses 150 billion Euro’s.
- 15. • Impact on nature Radioactive particles were released into the atmosphere and ocean – contaminated of groundwater , soil , seawater. After the accident the environment was totally changed.
- 16. • Effect on environment After the disaster , released substance damaged the environment
- 17. Solutions • Cores were installed with automated cooling system within 3 months after the disaster • Building was protected from storms and heavy rainfall. • New xenon gas ( common product of uranium fission ) detector were installed • Filter that reduce the amount of contaminants escaping into area and atmosphere • Cement that prevents contaminants from getting accidentally into the pacific ocean
