Since nuclear reactors have lower temperature limits than fossil fired plants with lower steam quality the turbine generator sets may be arranged to operate at half these speeds but with four pole generators to reduce erosion of turbine blades. Key characteristics are operation at or close to atmospheric pressure rather than the 75 150 times atmospheric pressure of typical light water reactors lwr hence reducing the large expensive containment structures used for lwrs and. A molten salt reactor msr is a class of nuclear fission reactor in which the primary nuclear reactor coolant and or the fuel is a molten salt mixture.
Hp turbine is usually double flow impulse turbine or reaction type with about 10 stages with shrouded blades and produces about 30 40 of the gross. Most of nuclear power plants operates a single shaft turbine generator that consists of one multi stage hp turbine and three parallel multi stage lp turbines a main generator and an exciter. Hp turbine is usually double flow reaction turbine with about 10 stages with shrouded blades and produces about 30 40 of the gross power output of the power plant unit.
Most of nuclear power plants operates a single shaft turbine generator that consists of one multi stage hp turbine and three parallel multi stage lp turbines a main generator and an exciter. A boiling water reactor heats up the water in the reactor until it boils into steam and spins the turbine. Both use steam to power a generator but the difference is how they create it.
The names can be a bit misleading. The nuclear reactors currently operating in the united states are either boiling water reactors or pressurized water reactors. They are used in the most nuclear power plants but there are many types according to the reactor type the boiling water reactor does not require steam generators since the water.
Steam generators are heat exchangers used to convert feedwater into steam from heat produced in a nuclear reactor core the steam produced drives the turbine. Nuclear power nuclear power plant steam generator. Hp turbine is usually double flow impulse turbine or reaction type with about 10 stages with shrouded blades and produces about 30.
Most of nuclear power plants operates a single shaft turbine generator that consists of one multi stage hp turbine and three parallel multi stage lp turbines a main generator and an exciter. Principle of operation of turbine generator electricity generation. Presently the vast majority of electricity from nuclear power is produced by nuclear fission of uranium.
Nuclear power is the use of nuclear reactions that release nuclear energy to generate heat which most frequently is then used in steam turbines to produce electricity in a nuclear power plant nuclear power can be obtained from nuclear fission nuclear decay and nuclear fusion reactions.
Nuclear turbine generator. Turbine generator power conversion system. The layout of nuclear power plants comprises two major parts. The nuclear island and the conventional turbine island the nuclear island is the heart of the nuclear power plant. On the other hand the conventional turbine island houses the key component which extracts thermal energy from pressurized steam and converts it into electrical energy.
A nuclear power plant is a thermal power station in which the heat source is a nuclear reactor as is typical of thermal power stations heat is used to generate steam that drives a steam turbine connected to a generator that produces electricity as of 2018 the international atomic energy agency reported there were 450 nuclear power reactors in operation in 30 countries.
