To develop a reliable source of electricity for Cambridge bay Risks: working in remote location
when building a large construction project, there are unknown cost involved. An important new risk
is the cost of complying with potential greenhouse gas emission regulations. Sea lift delays and the
potential of not having the contracts written on time and developed in detail. Estimated total costs. 3

2. Essay on Nuclear Energy
Nuclear energy
Nuclear Power and its uses is a growing discussion in today's era of technology. Australia is one of
the developed countries where the demands of energy resources are increasing rapidly. Nuclear
energy is coming up as a great alternative, but various factors support as well as oppose its growth.
Some countries oppose the usage of nuclear energy because of the problems associated with its
usage. Production and Maintenance of nuclear power is very expensive. Nuclear power is viewed as
too dangerous, uneconomical, and not required. Although, nuclear energy has a potential hazard, but
it is reliable in terms of efficiency, environmental impact and cost when compared with other sources
of energy. Therefore, the increase in the...show more content...
Though renewable sources of energy are reliable but their output greatly depends on the
environment. For example, cloudy days have no solar gain, hence no solar energy production. Quiet
days mean no wind blows to drive wind turbines. Dams are primarily for flood control, so
hydroelectricity production varies as dam water levels fluctuate.
Considering the case of Aswan Dam in Egypt not only caused thousands to loose their homes and
lives but also ceased the fertile surrounding because of the yearly inundation of the Nile. Moreover,
the subsequent silting up for the river destroyed much wildlife.
Due to Thermal Power Generation, 2500 million tons of coal each year is consumed to produce
38% of the electricity, While 61,000 tons of Natural Uranium will be used to generate the same
amount of energy (World Nuclear Association, 2005) .
Secondly, nuclear energy source has a weak impact on environment than the Non–renewable
resources. There is no doubt that use of fossil fuels leads to global warming. While, the amount of
carbon dioxide in the atmosphere was only 0.028% five decades ago, now, as per American
Petroleum Institute (1998) estimates it reached 0.036%. Additionally, burning of fossil fuels,
especially coal, oil, and natural gases are the main causes for increase in pollution; especially air
pollution. Several hazardous pollutants are produced by fossil fuels combustion: Carbon Monoxide,
Nitrogen Oxides, Sulphur Oxides and

3. Nuclear Essay
The UK civil nuclear power industry initially started in 1946 followed by the establishment of one
of the world's first nuclear power plant in 1956 [23–24]. This commercial scale reactor was built in
southwest Scotland and given a name "MAGNOX" due to the fuel cladding (magnesium
non–oxidising alloy) used to contain the fuels. The MAGNOX reactor uses natural uranium metal
fuel to generate thermal energy while using graphite bricks to moderate the fast moving neutrons
within the core. Two types of graphite bricks are used in MAGNOX design; these are Pile Grade
A (PGA) and Pile Grade B (PGB). The former is used as a neutron moderator due to its high density
and lower neutron absorption, whereas the latter is mostly used as a reflector [23]....show more

Currently, there are fifteen operating reactors in the UK with a combined total output around 8883
MWe, and one under construction [27]. Fourteen of the fifteen operating reactors are AGRs and
located at seven different power stations, making the AGRs the most dominant nuclear reactors in
the UK. The remaining two reactors (including the one under construction) are based on PWR design.
AGRs are the second generation of the UK nuclear power plants, and initially designed to improve
the steam cycle efficiency of the early reactor design (MAGNOX). This type of reactors exists only
in the UK and operated by EDF–Energy (formerly British–Energy). Since the AGRs first operation
in 1976 they have become the UK's most dominant reactor after showing an increased economic
benefits and steam cycle efficiency approximately 42% compared with MAGNOX reactor, which
has approximately 31% efficiency [25]. AGRs are capable of producing peak fuel temperature
approximately 800 В°C and the coolant gas temperature approximately 650 В°C at 40 bars. The
steam generated by the AGRs can reach up to 540 В°C at 165 bar, which is capable of driving the
standard 660 MW turbines.
Some of the main differences between the early MAGNOX reactors and AGRs that have a key
impact on the reactor

4. What is Nuclear Power? Essays
The process used was to gather information from books, the Internet, and interviewing my father who
works at a nuclear power plant.
There are many forms of energy. Coal, gas, oil, and nuclear power are the most common forms of
energy used in the United States. Three of these energies are limited: coal, gas, and oil. Nuclear
power is unlike the other three because it uses the fission process instead of combustion. This form
of power is unlimited. It produces heat energy like the others, but does not produce Carbon Dioxide
and other particulate emissions.
Nuclear Power is made by Nuclear Fission. To create fission you must split a nucleus (usually
Uranium) with a neutron. This...show more content...
Alpha particles are another type of radiation. Alpha particles are positively charged particles that
lose power rapidly. They are not dangerous to the skin tissue but if inhaled or ingested can be fatal.
A simple sheet of paper can stop Alpha Particles.
Also Beta Particles are radiation. Beta Particles are positive or negative electrons. They are like
Alpha Particles, they are only dangerous if inhaled or ingested. Clothing or aluminum can stop Beta
Particles. All of these types of radiation can be considered nuclear waste, but also often have uses. X
Rays use radiation to examine us. Radiation is used in medicine, dentistry, and industries. Remember
the next time you get an X– Ray you are exposed to radiation.
There are two types of reactors. One is the Boiling Water Reactor (BWR). First, pure water is
pumped into the reactor and boiled into steam. The steam travels through the containment structure
to the turbine. The turbine spins turning a generator that makes electricity. The steam goes to a
condenser. The condenser uses colder water (usually from a river or the sea) to condenses the steam
into water, which is reused by the reactor. A BWR has only one "side".
Boiling Water Reactor (BWR)
The second type is the Pressurized Water Reactor. The Pressurized Water Reactor is different from
