One of the byproducts is Plutonium which is commonly used in nuclear weapons. Also fission is used for Nuclear Weapons- what is meant by this is that the byproduct of fission allows for nuclear material to be produced as well as producing nuclear waste that can allow for nuclear weapons to be manufactured. The issue with the nuclear waste produced is that there are no restrictions or preventative measures that are enforced or in place to help with the environment.

The critical mass is the maximum size a sample of uranium ore can reach. If the sample is larger then the critical mass it will start an uncontrolled reaction. 99.3% of uranium ore is made up of uranium-238 and 0.7% is uranium-235. Nuclear fusion is the process in which two nuclei fuse together to form a larger nuclei. Hydrogen atoms are usually used in fusion reactions.
In nature this process is irrelevant due to the low natural occurrence and densities of radioactive isotopes. During weapons construction, however, isotopes are refined and concentrated to ultra-pure forms so that fission can occur at the ... ... middle of paper ... ...can be added on. The fusion reaction can go on to start another fusion reaction and so on with unlimited yield. The most powerful weapon ever conceived was of a similar design. The Russian "Tsar Bomba" (King of Bombs) was a fission-fusion-fusion weapon with an additional fission jacket surrounding the third stage that would have produced a yield of at least 100 megatons if it were ever exploded.
As humans, we have nearly mastered the art of nuclear fission. Currently, nuclear energy plants are responsible for about three-quarters of carbon free energy. This statistic shows that solar and wind power is used so minimally compared to nuclear energy. It releases little to no greenhouse gasses so environmentalists’ minds can be at ease. Using nuclear energy would not accelerate climate change because it does not affect the earth when it is being made or released.
Not to mention, the fuel needed for nuclear fusion is only deuterium and tritium, which is an isotope of hydrogen, the most common element on Earth. Also, the energy output is very high. For example, JET, the Joint European Tokomak can produce 16 MW in one pulse. That’s 16 million watts. Also, the waste product of the fusion reactor is not radioactive but is instead helium.
Uranium-235 is a non-renewable resource that will eventually run out, much like the fossil fuels. The abundance of deuterium and lithium provide a virtually unlimited supply of fuel for nuclear fusion. Therefore, nuclear fusion seems to be the better choice. Second, the potential amount of energy produced by fusion can greatly outweigh the fission. Initially, there are some disadvantages to fusion.
When a nuclear reaction happens, it releases tons of more energy than traditional sources of energy. There are Marino 2 economic advantages in creating power plants and using the energy in place if normal destructive energy. Finally, the transportation of energy requires little raw materials and is environmentally friendly . The waste produced by nuclear reactors needs to be disposed off at a safe place since they are extremely hazardous and can leak radiations if not stored properly. These wastes can be used to make nuclear weapons.
It is when two particles fuse together to create a larger one. It produces so much heat an energy though, that we have no way to contain it. Fission on the other hand, does not produce as much heat. We are able to contain it with materials that we currently have. This explains why we use fission in our nuclear reactors and not fusion.
Nuclear power is an inexpensive clean source of power. Others feel that because of the hazardous radiation emitted during the producing of the power and the radioactivity of the material used that nuclear power is not as good as the alternatives which are fossil fuels and solar power. (Hansen, 1993) If matter changes state or composition, it is accompanied by the production of energy. Processes such as combustion produce energy by rearranging the atoms or molecules of that substance. (Brain, 1998) An example of this is the combustion of methane (natural gas) CH(4) + 2O(2) = CO(2) + 2H(2)O + energy In this example the amount of energy released is eight electron volts or 8 eV.
Yet, the negatives are so heavily outweighed by the positives (i.e. high economic efficiency and low environmental impact), that they do not in any way draw from the fact that nuclear energy should definitely continue to be used, and more so. Nuclear power is extremely cost efficient. First, it requires a very small amount of Uranium-235, the most commonly used fuel, to produce a great amount of energy. Any given amount of Uranium-235 will produce 3.7 million times the amount of energy as the same amount of coal.
