Nuclear Fusion Disadvantages

Superior Essays
Introduction: With the constant rise for global energy, there is a huge demand for environmentally clean and cheap energy sources. Now, for many years power generated by nuclear power plants has been a reliable source for energy but the current amount of uranium, which is the fuel will satisfy the energy requirements for the next 200 years. Also, the nuclear reactors are not very efficient as not all of the uranium mined is being used to generate power. In this essay, I will discuss an alternate method of producing nuclear energy, its impact on the environment and the benefits and disadvantages that come with this new method.
There are 2 known types of nuclear reactions, one of them is nuclear fusion which can provide an inexhaustible source

It takes place at such high temperatures that the gas produced turns into plasma. Usually, fusion is not feasible because of the electrostatic repulsion between 2 nuclei but if circumstances can be achieved where the 2 hydrogen isotopes, deuterium and tritium are heated to such an extent that they can overcome electrostatic repulsion, the 2 nuclei can fuse to release a tremendous amount of energy. This is currently being achieved by the Tokamak reactors. Nuclear fusion doesn’t risk running out of deuterium and tritium because deuterium is found mainly in sea water and tritium can easily be obtained by bombarding lithium-7 with high energy neutrons. (Nuclear fusion, para. 3 …show more content…
The fusion core is surrounded with a blanket of fertile materials, materials who are not fissionable by themselves, but by thermal neutrons (0.025 eV) can become fissile materials, for example: uranium. The purpose of the blanket of uranium is to decelerate the neutron from the fusion reactor and thus begin the fission process with the fertile materials. Also, collision with the fertile materials, which is basically nuclear fission will also release 4-5 other neutrons which will then feed the fission reactor. (Barrett, Hardie, 6,

    The uranium around the world mostly lie under land controlled by tribes or indigenous people who don’t support it being mined from the earth. Mostly if they release waste then it will last up to 200-500 years before it actually goes away. This can be very bad to the environment and the U.S. doesn’t have no operating long-term waste storage sites but one is in progress nonetheless it’s already oversubscribed. That means that its nuclear waste will last a long time before it actually leaves and shipping nuclear waste poses an increased potential threat to intercept to nuclear terrorism. Presidio Buzz’s thoughts can show that there are many terrifying things that can happen with using nuclear fission.…

    Nuclear energy is the energy released during nuclear fission or fusion. Nuclear fission is a nuclear reaction in which a heavy nucleus splits spontaneously or on impact with another particle, with the release of energy. Nuclear fusion on the contrary is the exact opposite; it gathers energy from the heavy nucleus combining with the shot particle. These two combined produce a lot of energy that is used all over the world on a daily basis. Nuclear power has proved to serve a huge part of our society today.…

    The concepts of nuclear fusion and fission have recently taken a great role on the future of energy acquirement. Nuclear energy seemingly is the way of the future as it is exceedingly more efficient than any means of energy that which we have now. In nuclear power plants, fission is used to generate the power required to develop steam which then powers turbines. Fusion on the other hand, is essentially the reaction that occurs in the sun. Essentially, "Hydrogen nuclei (such as deuterium and tritium – basically, hydrogen with extra neutrons) fuse to form helium, and the mass defect is released as energy."…

    Fusion reaction is a reaction where light cores of hydrogen isotopes (deuterium and tritium) at high-speed collide with each other to form a heavier helium nucleus and a free neutron, which releases enormous amount of energy. Fusion reactor requires only about 30 grams of hydrogen isotopes (deuterium and tritium). At any time in the vacuum chamber there is less than one gram of fuel. We have deuterium in unlimited quantities in seawater, and tritium is produced from lithium, a lack of which we also do not have.…

    (Nuclear Chain Reactions) The two “types” of chain reactions, one is the controlled type, nuclear power, and the second is the uncontrolled chain reaction, nuclear weapons. The reaction can only continue if the additional fission keeps occuring, if not there would be no chain reaction. The uncontrolled reaction is not safe, which is why we use it as a weapon however nuclear power is safe. Nuclear power is safe because there is so much security surrounding it.…

    Beginning in the 1960’s nuclear power was believed to be an attractive alternative to fossil fuels and was even referred to as the energy source of the future. To the uninformed the use of nuclear energy may seem frightening because the only thing rumored is the negatives like: the waste, major spills of material and disastrous radioactive accidents, but there are many benefits from the use of this energy source such as: saving millions of lives, a mass reduction of pollution, and an advancement of technology. Although it may take a long time, society will benefit from this energy source. The reason why we should support the use of nuclear energy is because, “scientists have estimated that if all the accidents at nuclear reactors were averaged…

    When a neutron is absorbed by isotope of X-- given that X is some given element-- another isotope of X is created. Though sometimes these newly-created isotopes of X are very unstable. They may be so unstable, in fact, that they only exist briefly before splitting into two separate and distinct chemicals. Radioactive photons, massive energy, and neutrons are shot out in the surrounding area. As long as more Isotopes of X still exist in the area, this can, in turn, create a grand chain reaction that can theoretically last forever.…

    The two key attributes of atomic parting critical for the down to earth arrival of atomic vitality are both apparent in the second comparison above. In the first place, the vitality per parting is huge. In commonsense units, the splitting of 1 kg (2.2 lb) of uranium-235 discharges 18.7 million kwh as warmth. Second, the splitting procedure started by the retention of one neutron in uranium-235 discharges around 2.5 neutrons, on the normal, from the split cores. The neutrons discharged in this way rapidly cause the splitting of two more particles, in this manner discharging four or more extra neutrons and starting a self-supporting arrangement of atomic partings, or a chain response, which brings about ceaseless arrival of atomic vitality.…

    Invisible Yet Deadly In 1938 German Otto Hahn and his assistant Fritz Strassmann discovered that when uranium is bombarded with neutrons, through the process known as fission, there are two lighter elements, neutrons, and a large amount of radiation produced. It was clear that these neutrons could in turn also cause fission, producing more neutrons and developing a chain reaction which might spread throughout all the uranium present (Rinkesh). This fission reaction showed a lot of potential, and since the discovery of nuclear fission, scientists around the globe have developed different yet effective methods of harnessing the energy produced by the radiation ushered in an era commonly known as the atomic age.…

    The paper detailed how the energy was to be analysed, and also cited many sources saying that it can be analysed, and that the results would reflect reality. And while the efficiency in a nuclear reactor is approximately the same, the amount of energy produced is much higher. Even though the turbine technology is the same, the amount of heat in kWh produced by one kilogram of uranium is approximately 24 million compared to 8 from coal and 12 from mineral oil [4]. While these numbers aren’t precise, they give a general understanding of comparison.…

    Fission was used in the original atomic bombs, and fusion is most commonly used today. This is due to the fact that the amount of energy that can be released from fission is limited, whereas fusion can theoretically release an unlimited amount of energy. Fusion is the same type of reaction that occurs on stars, thus obviously very powerful. Fusion occurs when two atoms are “fused” together and release a stray neutron. Thermonuclear bombs are much more powerful, and produce significantly greater amount of gamma…
