Nuclear fission

A nuclear power plant uses Nuclear Fission to create energy. Nuclear fission occurs when a neutron passes by a heavy nucleus such as Uranium-235, the nucleus may capture the neutron which may or may not cause nuclear fission. If the reactor used is U-235 when a neutron is captured the energy is spread out through the 236 nucleons (both protons and neutrons) that are currently present in the nucleus. This nucleus is likely to break up into two fragments due to its instability. These fragments are usually half its mass. After the fragments have been created is followed by emissions of a neutrons usually between 2 and 3 (normally 2.5). Nuclear energy works as all energy works on Einstein’s equation of E=Mc2 , the fragments that are released are usually 99.9% of the mass of the original atom. The mass deficit of 0.1% is converted to energy in the form of gamma rays. Nuclear energy works by creating extreme amounts of heat due to the reaction that occurs when fission takes place. This heat is used to super heat water creating steam, the steam is used to power turbines and the turbines are attached to generators which produce electricity. Nuclear fission has a high output of energy per Kg but it comes with the downside of its toxic waste by product that is hard to safely dispose of. Natural disasters also need to be considered when evaluating whether to invest in nuclear energy or other “cleaner” types of energy such as solar and wind. If they town, city or country lies on a…

Two benefits of nuclear fission technology for society are that significantly fewer amounts of greenhouses gases are being released into the atmosphere, compared to fossil fuels. This results in a slowed rate of pollution and global warming. Another benefit is that power created through nuclear fission is immense and is able to meet the demands of large and industrial cities as well as the suburban towns too. Also the energy is quick to create too, which means that immense amount of energy can…

Elsa Gaston 1. Why is U-235 (the uranium isotope with a mass of 235 amu) a special element and what is it used for?- Under some conditions U-235 can be spilt and yield a lot of energy. It can be used for nuclear fission. 2. Describe nuclear fission and how the famous equation E = mc2 relates to this process?- It is when the nucleus of an atom splits into smaller nuclei or fission products. It is an exothermic reaction and a lot of energy is released. It is the equation that is in accordance…

is called nuclear fission. Nuclear Fission is a process in which an atom is split…

Both Nuclear fission and Nuclear fusion reactions have their advantages and disadvantages. In terms of energy that they produce fusion reactions produces relatively more energy compared to fission reactions however fusion reactions require more conditions for them to take place. They require higher temperatures which means that the energy that has to be inputted for them to work is way more compared to the energy inputted for the fission reactions because of this fact it might not be wise to…

There are two main kinds of nuclear reactions, nuclear fission and nuclear fusion. A nuclear reaction is when an element undergoes a change and becomes a new element. Nuclear fusion occurs when two elements “combine” and a new element is created. An equation for nuclear fusion would look like, 21H + 31H → 42He + 10n. (Nuclear Chemistry) The two Hydrogen atoms “combine” to become Helium, a new element. Nuclear Fission occurs when an large unstable element splits into smaller elements. An equation…

Uranium, like all the other elements, in several different forms, known as isotopes. most common isotope of uranium is , which makes up 99.28% of all uranium atoms. The second-most common isotope, is the one used to generate electricity, because it can easily undergo fission. nuclear fission is a very efficient source of energy, nuclear reactors require very little fuel. A single 20-gram uranium fuel pellet can produce the same amount of energy as 400 kilograms of coal, 410 litres of oil, or…

between Nuclear Fission and Nuclear Fusion. I will discuss each type of reaction and how they are related to the energy industry. I will also discuss why only fission reactors are currently used for nuclear power production and what the future holds for both nuclear fission and fusion. By definition, nuclear fission is the splitting of an atom into two smaller nuclei with the release of energy. Fission does not normally occur naturally in nature. This type of reaction takes place when a large…

Nuclear Fission Energy In nuclear plants they split the cells of uranium in a process called fission. Fission is splitting cells of atoms to create energy, this energy is important and useful because it helps power our homes and businesses. By powering our homes it helps us to do the simplest of tasks, such as; turn on the light, cook our dinner, and even charge our cellular devices. Another use if for nuclear weapons, by building and using nuclear weapons we as a country can help protect…

The breaking of the nucleus of an atom in a nuclear fission uses low energy but has a massive destruction like in a case of an atomic bomb. Controversial conferences and seminars portray nations taking hard stands on whether nuclear reaction should be used in war battles. From a theoretical point of view, it looks a simple topic yet it is not. The use of graphical and pictorial presentation on the effect will make sense to hardliners in use of nuclear fission gadgets. This is only possible with…
