	Nuclear Power Reactors
		In a nuclear power plant, the fission of Uranium atoms in the reactor provides the heat to produce steam for generating electricity.
		In most electric power plants, water is heated and converted into steam, which drives a turbine-generator to produce electricity.
		Heat is produced in a nuclear reactor when neutrons strike Uranium atoms causing them to fission in a continuous chain reaction.

	Four workers die in Japanese nuclear plant accident
		However, a review of the events leading up to the accident and the history of other nuclear industry incidents over more than a decade reveals that far from “ensuring safety”, the government, together with the self-regulated nuclear power companies, is squarely to blame for the horrific deaths and injuries suffered at the KEPCO plant.
		Two years ago, Tokyo Electric, Japan’s largest power company, was forced to close its 17 nuclear power plants temporarily after admitting that it had covered up inspection reports revealing dozens of cracks in its reactors during the 1980s and 1990s.
		The No. 3 nuclear reactor at the plant, which began operation in 1976, is said to have automatically shut down after the steam began leaking.

	Nuclear reactor - Wikipedia, the free encyclopedia
		In a nuclear power plant, the cooling system is designed to can make use of the heat by transferring it to a heat engine such as a steam turbine.
		Nuclear reactors are used for many purposes, but the most significant current uses are for the generation of electrical power and, in rare cases, for the production of plutonium for use in nuclear weapons.
		Power reactors also include a heat exchanger to remove heat from the working fluid of the reactor itself and drive an attached electrical generator, while research reactors include facilities for inserting samples into the core (and later removing them), or for extracting neutron beams from the core.

	Nuclear Power Plant, nuclear power plant location, nuclear power plant diagram, nuclear power plant map
		In the nuclear plant, the heat energy produced boils water into steam, which drives a turbine generator to produce electricity.
		The efficiency of a nuclear power plant in producing power is all about the fuel: In most cases a form of processed uranium that has been mined from the earth and processed and manufactured into fuel form for the power plant.
		One uranium nuclear fuel pellet the size of the tip of your little finger is equivalent to the energy provided by 1,780 pounds of coal; or 149 gallons of oil, as much oil as fits in three 50 gallon drums; or 17,000 cubic feet of natural gas.

	Nuclear Propulsion
		The components of the nuclear power plant include a high-strength steel reactor vessel, heat exchanger(s) (steam generator), and associated piping, pumps, and valves.
		Unlike commercial nuclear power plants, Naval reactors must be rugged and resilient enough to withstand decades of rigorous operations at sea, subject to a ship's pitching and rolling and rapidly-changing demands for power, possibly under battle conditions.
		US Navy nuclear ships are decommissioned and defueled at the end of their usefueli lifetime, when the cost of continued operation is not justified by their military capability, or when the ship is no longer needed.

	Ontario Power Generation - Operations
		The heat produced by this reaction is transferred, via a separate heavy water heat transport system to boilers where ordinary water is boiled and the resulting steam is used to drive a turbine generator that produces electricity.
		Pickering A - the first four of the Pickering reactors - went into service in 1971 and continued to operate safely until 1997 when it was placed in voluntary lay-up in 1997 as part of what was then Ontario Hydro's nuclear improvement program.
		The Pickering Stations A and B produce electricity with heat created by nuclear fission using natural uranium fuel.

	World Nuclear Association Information and Issue Briefs Nuclear Power in China
		China Power Investment Corporation (CPIC, formed from the State Power Corporation and inheriting all its nuclear capacity) is a major power generator and is the largest state-owned nuclear power investment and operating organisation.
		Nuclear power has an important role, especially in the coastal areas remote from the coalfields and where the economy is developing rapidly.
		Nuclear power has been a significant part of the electricity supply for two decades and now provides almost 40% of base load and 20% overall, though nuclear comprises only 14% of 36.3 GWe installed capacity.

	Pravda.RU:Hungarian nuclear power plant incident caused by "human factor"
		According to experts in nuclear energy, "they noted that as a result of steam generator decontamination in previous years, deposits became attached to the fuel assemblies.
		The fuel cleaning incident at the Hungarian Paks nuclear power plant on April 10, 2003 was caused by the underestimation of the "safety significance of the proposed designs for the fuel cleaning system", reads the IAEA experts' report published in Vienna.
		After carrying out inspections at the Paks atomic power plant, the IAEA experts worked out a number of recommendations for the Hungarian Atomic Energy Authority so as to minimise the detriment to the environment.

		Paks will use the reactor pressure vessel, steam generator and auxiliary equipment from the canceled Zarnowiec VVER-440 Model V213 nuclear plant in Poland in an IAEA training program scheduled to begin in 1996.
		The team identified three safety issues in its analysis of the plant's reported events: actions by staff that were contrary to written instructions or were carried out in the absence of written instructions; problems in plant operation associated with the vigilance of personnel and the safety culture; and problems associated with instrumentation and control equipment.
		Paks' safety enhancement program was reviewed on the basis of the AGNES study recommendations, and new priorities have been established for implementing safety measures.

	NRC: Steam Generator Action Plan
		Because of past problems with steam generator tubes affecting the operation of steam generators, the NRC continues activities related to improving tube integrity, as does the nuclear industry.
		Tube integrity is integral to the safe operation of steam generators.
		This plan is just one facet of NRC's overall strategy to maintain safe operation of nuclear power plants, increase public confidence in agency regulatory actions, and improve effective and efficient use of NRC's resources.

	Nuclear reactor
		Nuclear power can also be generated in a Radioisotope thermoelectric generator, which produces heat through subcritical radioactive decay rather than fission in a near-critical mass.
		In the vast majority of the world's nuclear power plants, heat energy generated by fissioning uranium fuel is collected in purified water and is carried away from the reactor's core either as steam in boiling water reactors or as superheated water in pressurized-water reactors.
		In either a boiling-water or pressurized-water installation, steam under high pressure is the medium used to transfer the nuclear reactor's heat energy to a turbine that mechanically turns an electric generator.

		As stated previously, the estimated cost of adding this nuclear generating capacity is approximately half the cost projected for purchasing the power and one-third the cost of producing the power by constructing a new combined-cycle, natural-gas-fueled facility.
		A power uprate increases the heat output of the reactor to support increased turbine inlet steam flow requirements and increases the heat dissipated by the [[Page 48483]] condenser to support increased turbine exhaust steam flow requirements.
