Nuclear energy is an alternative to using fossil fuels. Although nuclear energy is also nonrenewable, it has a much lower amount of air pollution, as well as a lower risk of affecting the climate through global warming. There are three main kinds of nuclear energy, nuclear fusion, nuclear fission, and radioactive decay. This report will explain how nuclear fusion works, as well as explaining the advantages and disadvantages of nuclear fusion.
Nuclear fusion occurs when two or more elements are fused together. Nuclear fusion cannot be used with elements that are heavier than iron, only lighter elements are used. Lighter elements produce more energy. Energy is produced because the mass of the combined elements is lower than the mass of the two separate elements. When the two nuclei combine, some of their mass is converted to energy.
All nuclei have a positive charge and repel each other, which makes it difficult to combine the nuclei. If the nuclei are brought close enough together, though, the nuclei’s attractive force will be high enough to combine the nuclei. The easiest way to bring the nuclei close enough to combine is by accelerating the nuclei. This can be achieved by heating the nuclei up to thermonuclear temperatures. The minimum temperature for achieving nuclear fusion is approximately 100 million Kelvin. At this temperature, hydrogen is plasma.
A fusion reactor reaches the high temperature and pressure needed for fusion. The power needed to start a reactor is about 70 megawatts, but the power produced is about 500 megawatts. Fusion reactions take from 300 to 500 seconds. The temperatures involved in nuclear fusion are too hot for a material container. There are two main kinds of fusion reactors. T...

Nuclear fusion has many advantages. One advantage of nuclear fusion is that nuclear fusion produces more energy than any other type of resource. A fusion reaction is measured in MeV, million of electrical volts. A single deuterium- tritium reaction can contain 14 MeVs.
Another advantage of nuclear fusion is that it does not pollute the air with carbon dioxide like burning fossil fuels. It also does not pollute the air with radioactive chemicals like nuclear fission. A third reason nuclear fusion is better is because nuclear fusion has a very small chance of serious nuclear mishaps. Nuclear fission produces many radioactive particles, nuclear fusion produces very few.
Nuclear power is a growing source of energy to most of the world for many benefits. People doubt the significant of nuclear power because of one accident. Due to this accident, the world has only seen the flaws in nuclear power and not the many benefits it has to offer. Nuclear power would benefit worldwide if people would let go of the past and look towards the future. Nuclear power is a better alternative energy because of its economic and environmental benefits.
Physicists started to realize that stable nuclei can be converted to unstable nuclei. Through such process, they discovered that heavy nuclei can undergo nuclear fission. While testing, they added a neutron to an isotope of Uranium 235. This resulted Uranium 235 to become unstable and break down into Barium and Krypton, releasing two to three more neutrons. The breakdown of Uranium 235 is called “fission”.
All these effects were the cause of the discovery of nuclear fission and its properties. Nuclear Fusion Nuclear fusion is the process used by the sun and the stars in our solar system to produce their energy. Fusion involves smashing hydrogen atoms together at high velocities to form helium, and the matter is made into energy.
Nuclear energy is a very powerful source of energy. Just a little bit is required to make large amounts of electricity, which powers 1 in 5 households in the U.S. Nuclear energy has been advanced over the years and has been relied on heavily by many countries today.
In a fusion, two atoms’ nuclei join to create a much heavier nucleus.1 The two atoms collide and together make a new atom while releasing neutrons in the form of energy. Imagine this as two cars in a head-on collision. When they collide, they stick together (not forming a new atom like in nuclear fusion, but let’s pretend,) and when they crash, some of the bumper flies off. The atoms collide and neutrons, like the bumper, fly off in the form of energy.
Cost and availability of fuel is a considerable factor when dealing with nuclear power. Fission requires an element that can be easily split in a particle accelerator, such as uranium or plutonium. Fusion, on the other hand, uses isotopes of hydrogen atoms, specifically deuterium and tritium, that can be obtained from ordinary water. Uranium ores occur naturally in many parts of the world but must go through a costly purification process before used as fuel. The unprocessed ore contains approximately 99.3% uranium-238, a non-fissionable isotope of uranium, and only about 0.7% of U-235 required for fission. One hydrogen atom out of 6700 appears as deuterium, a naturally occurring isotope of hydrogen with an extra neutron, and can easily be separated from the rest. 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.
Nuclear power is generated through a process known as nuclear fission which occurs when the uranium molecules are placed in the water. This process causes the water to heat up to boiling point and generates steam, from there it operates like most other power plants by using the steam to turn turbines and create energy. Stea...
Currently, plants use fission reactions, which is the bombardment of atoms with neutrons to split atoms into new materials, releasing the energy which we have all come to rely on. Fusion is essentially the opposite of fission. Fusion is the combination of atoms to make new elements, what is happening at the core of our sun currently. When atoms are fused, a massive amount of energy is released, making the cost of producing nearly free once fusion is obtained. One other large advantage of fusion energy is the by-products produced by the chain reaction in fusion. The second most abundantly used power source in fission reactors behind uranium is plutonium. Plutonium could be created by the fusion reactions, giving people not only energy from the initial reaction, but even more fuel to use for fission reactors
Nuclear power is generated by using electricity created during a controlled fission or fusion reaction (“Nuclear Energy.” Global Issues in Context Online Collection). Nuclear fission is a process that releases energy when a nucleus in one atom is separated into two nuclei. Nuclear fusion occurs when the nuclei of two hydrogen atoms are fused together producing a larger nuclei along with energy (“Nuclear Energy.” Opposing Viewpoints Online Collection). In the 1950s, the use of nuclear power became a realistic idea for countries with nuclear capabilities and nuclear power programs (“Nuclear Energy.” Global Issues in Context Online Collection). The international nuclear program grew rapidly and by 1999 there were 436 nuclear power plants in 32 different counties. The United States, Japan, Canada, Russia, India and France remain the largest users of nuclear energy since the 1990s; however, the dependency on nuclear power varies greatly around the world because of differences in the individual nuclear power programs availability of needed resources (“Nuclear Energy.” Opposing Viewpoints Online Collection).
...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. Without the additional fission jacket it still produced the largest nuclear explosion ever at 50 megatons.
Nuclear energy has is an overall success and continues to be because it is a reliable, efficient energy source that produces minimal pollution. Although it is a efficient energy source, it is also a massive destructive force that has been used in the past and can be used in the future if not properly defended against. America today can learn from instances in the 20th century such as the atomic bomb drops, exploration of fusion reactions, the knowledge gained from the three mile island accident, and from espionage. Nuclear technology is basically that manipulation of atoms in their current state. Usually radioactive elements such as high-grade plutonium or uranium are used in order to create a massive radioactive reaction that have the potential to obliterate any object in its way leaving a lasting negative effect on the environment. Nuclear energy was mainly researched for the atomic bomb droppings that occurred in 1945 as a result of Japanese oppression during World War II. The science of atomic manipulation, atomic radiation, nuclear fission and nuclear fusion was first developed in 1895. Research began to significantly speed up when the government took a large interest in the destructive force that nuclear weapons had the potential to hold. The only reason that the world ever had the experience of nuclear energy was because of World War II and oppression. Nuclear Energy came with a price of thousands of lives, that were not rightfully taken, but without those lives lost, our world would be different today, and we continue to learn from the mistakes and from the successes that we have had with nuclear technology.
One of the biggest and most prevalent problems is the need for clean, renewable, sustainable energy. On the forefront of these problems comes the following solutions: nuclear energy, hydro-electric energy, and photovoltaic energy. With the need for energy in today’s current world, exploring different ways of producing power is necessary. The differences and similarities between nuclear energy and alternative energy are important to look over and examine in depth, so that it is plain to see the positive and negative effects of energy production. To begin, nuclear power is produced by nuclear fission, which is the splitting of an atom to start a chain reaction (“11 Facts”).
Nuclear fusion occurs when two atomic nuclei collide with enough energy to bind together to form one nucleus. Nuclear fusion occurs in the core of our sun, and is the source of its tremendous heat. In the sun hydrogen nuclei, single protons, fuse together and form a new nucleus. In the conversion, a small amount of mass is converted into energy. It is this energy that heats the sun.
...ion of fusion power plant when the technology has achieved a certain level. This level will be reach with free market and patents right, which will create incentive for scientist to make innovation. Hopefully, countries, in the future, will find co-operating relationship’ among each other and solve environmental problems.
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.
