04 dez nuclear power plant structure
As of 2018[update], the International Atomic Energy Agency reported there were 450 nuclear power reactors in operation in 30 countries.[1][2]. Some of the systems work to keep the plant working correctly and safely. On June 27, 1954, the world's first nuclear power station to generate electricity for a power grid, the Obninsk Nuclear Power Plant, started operations in Obninsk of the Soviet Union. Nuclear Power Plant Main Parts or Component: The Nuclear Power Plant consists of 7 Main Parts: Nuclear Reactor; Coolant circulating pump; Heat Exchanger; Feed pump; Condenser; Turbine and ; Generator; Nuclear Reactor: The nuclear reactors are used at nuclear power plants for the generation of electricity and in nuclear marine propulsion. Retrieved March 25, 2011, from www.fas.org/sgp/crs/nuke/RS22542. However, Nuclear Consulting Group head, Paul Dorfman, warned the Gulf nation’s investment into the plant as a risk “further destabilizing the volatile Gulf region, damaging the environment and raising the possibility of nuclear proliferation.”[35], Nuclear reprocessing technology was developed to chemically separate and recover fissionable plutonium from irradiated nuclear fuel. Most Reliable Energy Source. That steam then drives turbines to generate electricity [source: NEI]. Introduction to Nuclear Power Plant 2. The nuclear reactor is the heart of the station. The electric generator converts mechanical power supplied by the turbine into electrical power. Isotopes are atoms of the same element with a different number of neutrons. Most nuclear stations require at least two distinct sources of offsite power for redundancy. [22], The nuclear power debate about the deployment and use of nuclear fission reactors to generate electricity from nuclear fuel for civilian purposes peaked during the 1970s and 1980s, when it "reached an intensity unprecedented in the history of technology controversies," in some countries. However states with a majority of the world's nuclear power stations, including the U.S., Russia, China and Japan, are not party to international nuclear liability conventions. GSR Part 4 for the identification of structures, systems and components (SSCs) important to safety in nuclear power plants and for their classification on the basis of their function … [15] Many countries have now liberalized the electricity market where these risks and the risk of cheaper competitors emerging before capital costs are recovered, are borne by station suppliers and operators rather than consumers, which leads to a significantly different evaluation of the economics of new nuclear power stations.[16]. [14] Where cheap gas is available and its future supply relatively secure, this also poses a major problem for nuclear projects. [citation needed]. News and information on nuclear power, nuclear energy, nuclear energy for sustainable development, uranium mining, uranium enrichment, nuclear generation … In a nuclear power plant, heat energy is generated by a nuclear reaction called as nuclear fission. The absence of secondary containment structures in Russian nuclear power plants allowed radioactive material to escape in Chernobyl [source: Salisbury]. Generally speaking, nuclear stations were originally designed for a life of about 30 years. A nuclear reactor is a machine used to inculcate a nuclear chain reaction. It was located within a large restricted area known as the Chernobyl Exclusion Zone. [29][30] Critics do not believe that these risks can be reduced through new technology,[31] despite rapid advancements in containment procedures and storage methods. Safety of Nuclear Power Reactors. U-238 has a longer half-life than U-235, so it takes longer to decay over time. The hot water modifies the environmental conditions for marine flora and fauna. However, the cost of proper long term radioactive waste storage is uncertain. nuclear power plant diagram [32][33][34] Those countries that do not contain uranium mines cannot achieve energy independence through existing nuclear power technologies.
