ABSTRACT
In our search for plausible forms of clean energy to replace fossil fuels, nuclear fusion is one of the most promising options. The purpose of this study is to investigate in detail the intricacies of nuclear fusion, the criteria that must be met in order to produce it, our progress in successfully inducing it, and why nuclear fusion is beneficial in relation to traditional fossil fuels. This is done by examining and analyzing information and data from scholarly sources. Concepts such as binding energy and the Lawson criterion, and machines such as tokamaks and stellarators, are discussed in this study in particular. The results …show more content…

This idea was then tested by Mark Oliphant, who, referring to Rutherford’s nuclear transmutation experiments, successfully fused hydrogen isotopes in his lab, and his conclusions supported those of Atkinson and Houtermans. Building upon the work of his peers, Hans Bethe used this new concept of nuclear fusion to explain how stars produce energy, and work out the steps of the main cycle of nuclear fusion in stars. However, largely funded research into nuclear fusion only began due to military incentives, during the Second World War, as part of the Manhattan Project. This research cumulated in the development and testing of the first hydrogen bomb, the Ivy Mike, which used nuclear fusion to produce a massive explosion. Research into harnessing the power of nuclear fusion for civil purposes only started in the 1950s, and this will be a large focus of this study.
WHAT IS NUCLEAR FUSION?
First of all, we must define nuclear fusion. Nuclear fusion is a nuclear reaction in which atomic nuclei collide at high speeds to produce energy and form a new, larger nucleus, along with other products in some cases.

For example, the energy released by a deuterium-tritium collision, both isotopes of hydrogen, is 17.6 MeV. One gram of matter used in this reaction would result in an incredible 339 GJ. In comparison, only 13.6 eV is released by adding an electron to a hydrogen nucleus. While individual atoms in nuclear fission do produce more energy than individual atoms in nuclear fusion, because atoms are much lighter in fusion than in fission, the energy per unit of mass is far greater in nuclear fusion than in fission. This means we cannot disregard the immense potential in nuclear fusion as a clean energy source.
NUCLEAR FUSION IN NATURE: STARS The most significant fusion processes in our universe are the ones found in stars, which provide the energy for the stars to burn and shine. Two different cycles in particular occur most within stars, depending on their size. Figure 3: The proton-proton chain

hydrogen bomb or H-bomb, weapon inferring an extensive bit of its vitality from the atomic combination of hydrogen isotopes. In a nuclear bomb, uranium or plutonium is part into lighter components that together weigh not exactly the first iotas, the rest of the mass showing up as vitality. Not at all like this splitting bomb, the hydrogen bomb capacities by the combination, or joining together, of lighter components into heavier components. The deciding item again weighs not as much as its parts, the distinction afresh showing up as vitality. Since to a great degree high temperatures are required with a specific end goal to start combination responses, the hydrogen bomb is otherwise called an atomic bomb.

However, mostly due to fear and the lack of knowledge, many are adverse to the use of nuclear power. Nuclear energy comes from two methods, fusion and fission. Fusion brings together tritium and deuterium to create heat energy, helium, and a neutron (Duke Energy, 2013). Nuclear fusion releases more heat energy than fission, however it is more difficult to control, so it is not currently a viable energy process (Duke Energy, 2013). However, the sun is an example of nuclear fusion, in how it produces heat.

On the first day of November in 1952, president Harry S. Truman tested the very first H-bomb on a remote island located in the Pacific Ocean. Common people were not supposed to know, but the information about the detonation were released more than 14 days later. After the atomic bombs were dropped in Japan, our government did not continue the idea of the creation of the hydrogen bomb until the Soviet Union was able to successfully explode their atomic bomb in 1949. President Truman demanded the invention of the hydrogen bomb (1).

Williams 1 Sam Williams English III: A-2 Mrs. Cox 6 April 2018 A Time of Great Change The 1950s, but more specifically 1950 to 1955, were a time of incredible progress and change for America and the world as a whole. The period between 1950 and 1955 was one of the most influential times in history because of the unique political landscape, groundbreaking scientific achievements, and major world events. The first half of the 1950s was extremely important to world history because the political landscape shaped much of the policy and ideologies of today. The Red Scare of the 1950s still influences Americans’ opinions of the government, communism, and Russia.

Nuclear power produces fewer carbon emissions than traditional energy sources because energy is not produced by burning molecules but splitting atoms. ‘An energy mix including nuclear power has the lowest impact on wildlife and Ecosystems’ as shown by a Conservation Biology paper. Consequently, greenhouse gas emissions have reduced by nearly half which shows the benefits and popularity of nuclear power use. Nuclear power has many environmental benefits such as small waste production, leaves no adverse effect on water, land or any habitats. By reducing fossil fuel consumption and switching to Nuclear Energy, we will sustain the environment, quality of air, improving the overall quality of

During the 1940s the world was in conflict and the allied forces, consisting of the USA, Britain and France were struggling to win the war against the Fascist movement. This led to innovations of all kinds and when the Japan got involved the US couldn’t land and hold an island without meeting great resistance from Japanese troops willing to commit suicide for their country. During this time many physicists and nuclear engineers were on the verge of constructing the next level of nuclear technology. This led to President Roosevelt establishing the National Defense Research Committee in hopes of creating an Atomic weapon capable of mass destruction.

An atomic bomb is a nuclear weapon, which its energy is being hardness from the element of uranium or plutonium. With the smallest amount of matter, it could transform to a huge devastation. It was the first nuclear weapon used during World War II. This resulted in the creation of a secret program called “The Manhattan Project.” The United States developed two atomic bombs during this time.

The singer, Eric Burdon, once said that “Inside each of us, there is the seed of both good and evil. It's a constant struggle as to which one will win. And one cannot exist without the other.” Good and evil must coexist in the world; in order for us to know what goodness is, we must know about evil. If we have no sense of what goodness is, then evil is nonexistent.

On April 14 of 1989 two scientists made a claim on Fudging Fusion. Those two where and are Dr. Micheal Mckubre ,Dr. Eugene Mallove. Both of them at first were laf at because people that that they were crassly. But then on 11 August, ARPA-E gave advanced warning of the new funding stream, called Accelerating Low-cost Plasma Heating and Assembly (ALPHA), so that researchers would have time to form into teams to bid for funding. The funding opportunity will be formally announced later this month or in September.

In this diagram, a neutron is absorbed by a uranium-235 nucleus, as a result, it turns of a small period of time to an excited uranium-236 nucleus, with the excitation energy provided by the kinetic energy of the neutron plus the forces that bind to the neutron. The uranium-236 then splits into two, smaller, lighter, fast-moving elements (these are known as fission products) and releases three free neutrons as well as gamma rays. Fusion and fission are nuclear reactions. Fusion is the binding of two atoms to produce a heavier atom while fission is splitting of an atom. Fusion releases more energy than fission and powers the stars.

“Nuclear power will help provide the electricity that our growing economy needs without increasing emissions. This is truly an environmentally responsible source of energy.” Michael Burgess Prior to the introduction of nuclear energy, fossil fuel was thought to be the only available source in producing energy. Although fossil fuel, such as coal, petroleum, and natural gas, contains high energy value, it produces too many harmful byproducts that ultimately pollute our environment. With the rising concerns over global warming as more and more greenhouse gases accumulate in our Earth’s atmosphere, many voice such opinions that new alternative, yet sustainable method must be adopted to produce energy.

Nuclear energy is something that we`ve all heard about. It carries risk and potential. When an atom (Uranium and Plutonium in nuclear power plants) is bombarded by neutrons, it can be split, causing fission. This fission releases more neutrons, which causes a chain reaction. Nuclear power plants use this use the heat that is created by fission to heat water that spins their turbines (“Nuclear Energy”).

Energy is the lifeblood of industrial economies and the key to new developments for developing nations. Secure energy is a matter of reliable, adequate, and affordable supply. Higher oil and gas prices have not only been painful for many economies, but a spate of price disputes has also brought the vulnerability of supply into sharp relief. Nuclear power is increasingly seen as a way to reduce dependence on foreign oil and natural gas, to combat rising energy costs, and to achieve ever-elusive. Nuclear energy is a clean, safe, reliable and competitive energy source.
