NUCLEAR ENERGY

The pursuit of nuclear energy for electricity generation began soon after the discovery in the early 20th century that radioactive elements,such as radium,released immense amounts of energy,according to the principal of mass energy equivalence.However mean of harnessing such as energy was impractical,because intensenly radioactive elements were,by their very nature,short-lived(high energy is correlated with short half-lives).After World War II,the prospects of using "atomic energy' for good,rather than simply for war,were greatly advocated as a reason not to keep all nuclear research controlled by military organizations.However most scientists agreed that civilian nuclear power would take at least a decade to master,(such as those in United States,UK,Canada,Russia,and France)attempted to keep reactor nuclear research under strict goverment control and classification.On July 27,1954,the Russia Nuclear Power Plant become the world's first power plant to generate electricity for a power grid,and produced around 5megawatts of electric power. Just as many conventional  thermal power stations generate electricity by harnessing the thermal energy released from fossil fuels,nuclear power plants converted to energy via nuclear fission.It is often  claimed that nuclear stations are inflexible in their output,implying that other forms of energy  would be required to meet peak demand.Nuclear plants are routinely used in load following mode on a large scale in France.A nuclear reactors is only part of life-cycle for nuclear power.The process start with mining.Uranium  mines are underground,open pit,in-situ leach mines.In any case,the uranium ore is extracted,usually converted into a stable and compact form such as yellowcakes.Here,the yellowcake is converted to uranium hexafluride,which is then enriched using various techniques.
