Nuclear Energy 1. What is nuclear energy? Text Book Pg 80 2. Nuclear Fission :- In nuclear physics and nuclear chemistry‚ nuclear fission is a nuclear reaction in which the nucleus of an atom splits into smaller parts (lighter nuclei)‚ often producing free neutrons and photons (in the form of gamma rays)‚ and releasing a tremendous amount of energy. The two nuclei produced are most often of comparable size‚ typically with a mass ratio around 3:2 for common fissile isotopes.[1][2].The smallest

Zuha Nihan Naseer male’ maldives Will we ever … have reliable nuclear fusion power? In the era of global climate change‚ and concerns about humanity’s long-term reliance on fossil fuels‚ many think the solution lies in alternative sources of energy‚ including nuclear power. All our nuclear power plants are based on fission: splitting heavy atoms into lighter components in a controlled fashion. Though fission is safe when all goes well‚ the fuel is radioactive‚ waste disposal can be

Nuclear engineering is the practical application of the breakdown of atomic nuclei and/or other sub-atomic physics‚ based on the principles of nuclear physics. It includes‚ but is not limited to‚ the interaction and maintenance of nuclear fission systems and components specifically‚ nuclear reactors‚ nuclear power plants‚ and/or nuclear weapons. The field may also include the study of nuclear fusion‚ medical and other applications of (generally ionizing) radiation‚ nuclear safety‚ heat/thermodynamics

Nuclear Weapons Since‚ a long period of time we have the invention of nuclear weapons of GLOBAL peace and constancy. Is it really right to say that nuclear weapons are peacemakers? Or they are killing weapons? Nuclear weapons are a volatile device that deduces its destructive force from the reactions of nuclear‚ either nuclear fission or a combination of both fission and fusion. Both chemical reaction releases huge quantities of energy from comparatively small amount matter. Simply‚ nuclear weapons

term Nuclear Power or Nuclear Energy gets used usually the first things that come to mind for most people are bombs‚ destruction‚ war‚ and deformed humans. Which in fact are four things that occur the least in the nuclear power field. Nuclear power is much more than just bombs and destruction‚ bombs barely even take up a percentage of the total amount of nuclear energy used in the world today. Most all of the nuclear energy used today comes in the form of production of electricity. Nuclear power

NUCLEAR REACTORS A nuclear reactor is a device to initiate and control a sustained nuclear chain reaction. Nuclear reactors are used at nuclear power plants for electricity generation and in propulsion of ships. Heat from nuclear fission is passed to a working fluid (water or gas)‚ which runs through turbines. These either drive a ship’s propellers or turn electrical generators. Nuclear generated steam in principle can be used for industrial process heat or for district heating. Some reactors are

Nuclear disasters From Wikipedia‚ the free encyclopedia The list of the worst disasters at nuclear power plants and other facilities all over the world is presented below: During the 2011 Fukushima nuclear emergency in Japan‚ three nuclear reactors were damaged by explosions. Following an earthquake‚ tsunami‚ and failure of cooling systems at Fukushima Daiichi Nuclear Power Plant in Japan on March 11‚ 2011‚ a nuclear emergency was declared. This was the first time a nuclear emergency had

Topic: The disadvantages of nuclear technology outweigh the benefits With the development of technology ‚ a considerable number of nuclear stations have built up throughout the world .The statistics on this issue that about more than 30 countries have nuclear stations or use them to generate power such as the USA‚ Canada‚ German‚ the UK and China. On the one hand‚ these countries obtain huge benefit of nuclear technology‚ but on the other hand‚ some pollution‚ cost expense and health problems

** Atom and Introduction to Nuclear physics ** Introduction Alpha-particle scattering 2.1 Experimental set-up ➢ Alpha particle o is a high-energy helium nucleus with 2 protons and 2 neutrons. o has 2 positive charges. ➢ Gold foil was chosen since it has a high atomic mass. Thin gold foil‚ ~10-6m was bombarded by high-energy alpha particles. ➢ Angular deflections/ scattering of alpha particles were measured by observing

than 230(mass). They are really slow and spontaneous. Fission = splitting. Can create a chain reaction. (picture above). Critical mass= must be enough mass in a reaction or enough fission type mass‚ fissionable mass‚ for the reaction to continue to go on.(minimum amount). Sub critical mass= mass of fission material that doesn’t have enough to keep the reaction going. Super critical mass= so much mass that there is to much where this rate of fission reaction can start increasing and can be very dangerous
