Nuclear Fission Research Paper
A nuclear power reactor uses a reaction called nuclear fission to produce a large amount of energy in the plant. The nuclear reactor produces electrical energy the same way in which other power plants do. The only difference is how heat is created. Power plant that run on fossil fuel burn coal, oil or natural gas to generate heat. In nuclear energy, heat is produced through nuclear fission. Nuclear Fission is a process where a large atom such as Uranium or Plutonium splits into two smaller atoms, known as fission products and some product particles. Uranium or plutonium isotopes are used as a fuel in the nuclear reactor. The amount of energy released from the nuclear bonds is much larger than the amount of energy in a chemical bond. For example, …show more content…
Uranium is a naturally element found in most rocks but also in soil, river and ocean. Uranium comes in slightly various forms known as isotopes. Some of these isotopes are radioactive and differ from each other based on the number of neutrons (different atomic number) in the nucleus. Uranium that is naturally occurring on earth is largely a mixture between two following isotopes. Uranium-238 accounts for 99.3% while uranium-235 accounts for 0.7% of uranium on earth. Uranium-235 is the fuel that is usually used in nuclear power plant. Uranium-235 is ideal for nuclear power because it can decay naturally by alpha radiation and release alpha particles. (Two protons and two neutrons). Also, Uranium-235 can undergo induced fission. This means when a free neutron collides with a U-235 nucleus, the nucleus will obtain the neutron and split it very quickly. The protons and neutrons in the nucleus of a uranium atom are split by the energy known as nuclear binding energy. Protons and neutrons binding energies are the energies required to release them from the nucleus. In binding energy, the mass the actual mass is always less than the mass of the nucleons (Protons + Neutrons) combined due to the energy released when the nucleus is formed. This is known as mass defect. So in this case, it release energy in the form of heat in nuclear fission to heat up

    Because the neutrons can continue to split uranium atoms and set in motion a chain reaction and create such intense amount of thermal energy that actually leads to the meltdown of the very mechanism that is required to harness the energy engineers at nuclear plants must absorb excess neutrons with control rods or water to regulate the rate of the reaction. In a pressurized light water reactor, the most common type of nuclear reactor, uranium fuel rods are placed in water, which slows neutrons so that fission can occur. After a fission reaction is initiated it becomes necessary to soak up the excess neutrons produced when uranium nuclei divide, so that on average only a single uranium atom from each…

    Nuclear power is produced through the use of nuclear reactions to produce nuclear energy that can then be harnessed to generate heat and create superheated steam to drive turbines. The most common nuclear reaction is that of nuclear fission, which is the splitting of an atom’s nucleus into smaller nuclei. Nuclear reactions are incredibly energy dense and thus allow nuclear reactors to make a tremendous amount of electricity. There are only 61 nuclear power plants in the United States, but they account for 19 percent of the entire country’s electricity production. [8][14] There are 7,304 total power plants in the United States, so nuclear plants on average produce over twenty-eight times as much energy as another plant in the U.S.…

    Nuclear energy is created by a specific nuclear reaction in which atoms are split ( nuclear fission ). This is a necessity to produce energy due to the fact that nuclear energy is the energy in the nucleus of an atom. There a substantial amount of energy in the nucleus because energy is what holds the nucleus together and is where the energy is produced from. This process occur in a power…

    As the nuclei break up, they release neutrons. When the neutrons hit other uranium atoms, those atoms also split, releasing neutrons of their own, along with heat. These neutrons strike other atoms, splitting them. One fission triggers others, which triggers still more until there is a chain reaction.…

    Nuclear Fission reactions differ from natural radioactive decay both in how the reactions are started and also the products that are formed. Radioactive decay happens when the nucleus is unstable due to the number of protons and neutrons within the nucleus. The nucleus is made stable by the emission of particles from the decaying nucleus. In nuclear fission a neutron is fired at an atoms nucleus, if the neutron has given the atom enough energy it will enter an excited state and begin to…

    Nuclear energy uses nuclear fission to generate heat. Nuclear fission is where atoms are split apart which releases energy. All nuclear power plants use nuclear fission. Nuclear fission is where a neutron hits a uranium atom and splits it releasing a large amount of energy. More neutrons are released when a uranium atom splits hitting more uranium atoms. This is called a nuclear chain reaction.…

    Nuclear fuel goes through fission when struck by free neutrons and then generates neutrons when it breaks apart. Only U-235 uranium atoms, a nuclear fuel, could be used for the chain reaction. This was because it was able to be obtained in large enough quantities to even be useful.…

    Uranium (U) is a metallic, silver-gray element that is a member of the actinide series. It is the principle fuel for nuclear reactors, but it also is utilized in the production of nuclear weapons. Because uranium is radioactive, it is constantly emitting particles and changing into other elements, like thorium. Uranium has a well-established radioactive decay chain. U-238 and U-235 (which has 143 neutrons) are the most common isotopes of uranium. Uranium naturally includes all three isotopes (U-238, U-235, and U-234) [3]. Once Uranium enters your body in any way, it is widely distributed. Bone acts as a reservoir for the metal. Uranium produces chemical damage to the body and about 60-80 % of tissues such as the kidneys and bones accumulate…

    Nuclear energy can be very dangerous but can also be cleaner than other energy sources by creating less pollution than fossil fuels. It is an advanced form of energy that has only been available for the past 50 years. It is very similar to fossil fuel in that it uses steam turbines to produce electricity. It uses uranium to produce heat in a process called nuclear fission where neutrons are smashed into the nucleus of atoms splitting them and releasing heat energy.…

    Uranium is a metallic mineral and an important natural resource. It is used in the process of making nuclear energy. Uranium is processed into a form known as yellowcake which is used in nuclear reactors to create energy. In Canada, it is located mostly in northern Saskatchewan.1As well there are smaller deposits of uranium located in Northwest Territories and in western Ontario. There is an estimated 487,200 tonnes in Canada, the fourth most in any country in the world. The uranium is used mostly for industrial use in the process of creating nuclear energy, but is also used in other applications such as medical uses like radiation therapy and scientific experimentation with radiation. 2…
