Introduction:
Nuclear energy is generated by a process called fission. Fission occurs within the reactor of a nuclear power plant when a neutron is fired at an atom of uranium causing it to split and release subsequent neutrons.1 These are able to crash into other uranium atoms causing a chain reaction and releasing a great deal of heat energy.
Advantages and Disadvantages:
As one of the greatest alternatives to fossil fuels, an important advantage of nuclear energy is the significantly lower emission rate of CO2 in comparison to plants which use coal and natural gas.2 Nuclear power is not reliant on fossil fuels and therefore producing energy by this method reduces pollution and the contribution to climate change. However, whilst the actual process of generating energy releases few emissions, uranium must be mined and purified and in the past this has not always been an environmentally clean process.2 Ultimately, uranium will one day run out, but nuclear reactors are versatile and may also run on Thorium. Despite being finite, this would allow nuclear power stations to function for a longer period of time.
The energy produced from nuclear reactions is very dense, providing almost ten million times more energy per atom than fossil fuels.2 In addition, nuclear plants are cost competitive, being no more expensive than alternative sources. Although there are huge initial start up costs, the only other expenses are the costs to process nuclear fuel, safely remove and store radioactive waste and daily upkeep of the plant.2
The greatest disadvantages of nuclear energy are the risks posed to mankind and the environment by radioactive materials. ‘On average a nuclear plant annually generates 20 metric tons of used nuclear fuel cla...

...he building of four nuclear plants to try and ease the transition from finite fuels.21The reactors used in these plants will be able to last longer and will run on 17% less uranium per energy unit than reactors in use currently. EDF estimate that their new reactors are capable of supplying up to 30% of the UK’s total energy. 21
Whilst there are clear arguments for and against nuclear energy, the future is promising; with scientists working on potential breakthroughs such as nuclear fusion, and the design of newer and better and reactors. Nuclear fusion is a reaction which causes the nuclei of atoms to collide and form a new atomic nucleus. It is essentially what heats the sun and stars and would produce no long-lived radioactive waste.22 If scientists could control the process of atomic fusion then it could become a never ending energy source for future use.
Non-renewable resources such as fossil fuels have been used up by society on a daily basis and have forced the world to find a new, clean energy source. The rising price of oil and the constant emission of carbon dioxide are proof that in the future our lives will be much harder to live. One answer to this problem is nuclear power, which has shown its efficiency during the times of World War II but has not been used commercially due to the challenges of dealing with nuclear waste and proliferation. In today?s modern era, nuclear power has been used in liquid metal fast breeder reactors, reactors that use uranium-238 to produce plutonium-239.
After World War II, nuclear power became the world’s shining energy hope. Technically it is produced when neutrons split the nucleus of uranium atoms releasing heat which is used to boil water and produce the steam that drives a plant’s turbines. Nuclear...
There are many sources of energy today, and the best source of it is constantly being sought after, one source stands out above the rest. Nuclear energy is simple in theory, yet it may be one of the most controversial sources of power. Nuclear energy works using reactors built to split the atoms (nuclear fission) of the fuel to produce heat. This heat evaporates the cooling agent (usually water) into steam which turns turbines to create electricity. Nuclear energy should be allowed, because it produces an abundance of electricity, as well as being a clean source of energy with no harmful emissions. Nuclear energy is the future of clean, environmentally friendly energy.
Nuclear power, or nuclear energy, is the use of exothermic nuclear processes,[1] to generate useful heat and electricity. The term includes nuclear fission, nuclear decay and nuclear fusion. Presently the nuclear fission of elements in the actinide series of the periodic table produce the vast majority of nuclear energy in the direct service of humankind, with nuclear decay processes, primarily in the form of geothermal energy, and radioisotope thermoelectric generators, in niche uses making up the rest. Nuclear (fission) power stations, excluding the contribution from naval nuclear fission reactors, provided about 5.7% of the world's energy and 13% of the world's electricity in 2012.[2] In 2013, the IAEA report that there are 437 operational nuclear power reactors,[3] in 31 countries,[4] although not every reactor is producing electricity.[5] In addition, there are approximately 140 naval vessels using nuclear propulsion in operation, powered by some 180 reactors.[6][7][8] As of 2013, attaining a net energy gain from sustained nuclear fusion reactions, excluding natural fusion power...
The production of nuclear energy is not as safe and clean as some say that it is. The Oxford Research Group released a report providing evidence that supports this point. It is clear that nuclear power plants do not produce a lot of carbon dioxide when they operate, but it is the mining of uranium and the storing of waste that produces the carbon dioxide pollution. This way of producing power is not as friendly to the environment as once thought. The report states that over time more carbon dioxide will be produced because more equipment and energy will be needed to extract uranium ore and store the waste. It is estimated by 2070 uranium nuclear power would produce as much carbon dioxide as a gas fired power station. If the use of nuclear power continues to increase this number would increase as well having a significant impact on global warming and the environment (Herbst).
Now in our modern society we have a big need for energy and are trying to find alternative types of energy power plants. Nuclear power plants are used in more than 30 countries all around the world (World nuclear association, n.d. para.3). These power plants are able to generate electricity continuously for many months at a time without interruption (World nuclear association, n.d.para.2). Nuclear power plants produce electricity by going through the process of fission. They have pros and cons as well, they can bring more jobs helping out the economy but also the radiation waste that is given off of the plants can harm many people’s health.
The world is facing an energy crisis and many are unaware of this growing problem. Sustainability is avoiding depletion of our natural resources in order to provide for future generations, and the only way to ensure that resources are available into the future is to find alternative sources to meet the world’s energy needs. Nuclear energy is just one source of alternative energy being implemented today in an effort to support the needs of the population and mitigate global climate change. Nuclear energy holds the necessary benefits in order to continue being used globally as an alternative solution.
Nuclear power is the generation of electricity from an atomic reaction. (World Statistics: Nuclear Energy Around the World n.d.) Though it produces zero carbon emissions there has been a decline in support for nuclear power and increased its support for alternative energies in the pursuit for a fossil free energy sector. Factors that have resulted in the reduction of support for nuclear energy include nuclear accidents and waste and the positives of renewable energy which include clean energy, sustainable and reduced health and environmental risks.
As a source of energy, nuclear energy provides a safer alternative, for the production of energy for large-scale consumption. There are two different types of nuclear energy; nuclear fission and nuclear fusion. Nuclear fission is the process in which a nucleus spits into two or more smaller nuclei. Nuclear fusion is the process in which two nuclei fuse together to form a larger nuclei. Nuclear reactors can become unstable creating an uncontrollable nuclear reaction. The effects of this can be seen in Chernobyl. Reactors have been designed safer after this disaster.
Here is where the process of nuclear fusion comes in, nuclear fusion is the process that stars use to create their energy, it involved fusing together two hydrogen atoms to produce helium and a very large amount of energy. Compared to nuclear fission, the process of fusion is alot safer as ...
Nuclear power has grown to be a big percentage of the world’s energy. As of January 18, 2013 in 31 countries 437 nuclear power plant units with an installed electric net capacity of about 372 GW are in operation and 68 plants with an installed capacity of 65 GW are in 15 countries under construction. As of end 2011 the total electricity production since 1951 amounts to 69,760 billion kWh. The cumulative operating experience amounted to 15, 15,080 years by end of 2012. (European Nuclear Society) The change that nuclear power has brought to the world has led to benefits in today’s energy’s usage.
Nuclear energy is energy inside the nucleus of an atom and it is the energy that is holding the proton and neutrons together. Nuclear energy can be converted by a power plant into electrical energy and the power plant is called nuclear power plant. There is two ways to obtain the energy. There is nuclear fusion and nuclear fission. Nuclear fusion is where atoms are combined together to form a larger atom and nuclear fission is where the atoms are split to produce the energy. In fact, nuclear power plant only can use nuclear fission to produce energy.
Around 1894, scientists discovered that by bombarding a radioactive substance with neutrons, a highly powerful energy could be produced. This is ionizing radiation, which is strong enough to rip the electrons from the nucleus of an atom, hence the name “nuclear energy.” over a century later, nuclear substances are harnessed in order to provide energy. However, nuclear energy is not only discussed amongst scientists, but anyone fearing the safety and future of the environments surrounding the area where a nuclear power plant is implemented.
The purpose of this report is to investigate the different views and opinions on the safeness and cost effectiveness of nuclear power compared to other forms of energy. This report will explain the issues and background of the debate, the importance of the issue, and the parties who are involved in this debate with their thoughts.
The use of nuclear energy has increased in the United States since 1973. Nuclear energy's share of U.S. electricity generation has grown from 4 percent in 1973 to 19 percent in 1998. This is excellent news for the environment. Nuclear energy and hydropower are the cleanest large-scale means of electricity production. Since nuclear power plants do not burn fuel, they emit no combustion byproducts—like carbon dioxide—into the atmosphere (www.nei.org). Nuclear power can come from the fission of Uranium, plutonium or thorium or the fusion of hydrogen into helium. Today uranium (U-235 and U-238) is most commonly used in the production of nuclear energy. The expa...
