Structure of a Nuclear Power Plant
A steam turbine is an equipment that is used to convert the heat into mechanical energy. The generator in a nuclear power plant converts kinetic energy supplied by the turbine into electrical energy. The cooling system removes heat from the reactor core and transports it to another area of the station, where the thermal energy can be harnessed to produce electricity or to do other useful work.
Nuclear Power Plant
In the case of an emergency, safety valves can be used to prevent pipes from bursting or the reactor from exploding. The water level in the steam generator and the nuclear reactor is controlled using the feedwater system. Most nuclear stations require two distinct sources of offsite power feeding station service transformers that are sufficiently separated in the station’s switchyard and can receive power from multiple transmission lines.
The element uranium is used as fuel in nuclear reactors for the chain reaction to occur. Uranium is a very heavy metal mostly found in seawater & rocks.
Nuclear Power Plants in India
In India, Nuclear power holds the fourth position among the different resources of electricity, Thermal, hydro and renewable resources being first, second and third respectively. Presently 19 nuclear power plants in India are there, which generates 4,560 MW (2.9% of total installed base) and 4 such power plants are in the pipeline and would be generating around 2,720 MW. India's contribution to fusion development is done through its involvement in the ITER project.
Since the beginning of the 1990s, Russia has always been a chief supplier of nuclear fuel to the country of India. The deterioration of domestic uranium resources caused the decline of electricity production from nuclear energy in India by 12.83% from 2006 to 2008.
Currently, twenty-two nuclear power reactors have a total install capacity of 6,780 MW (3.5% of total installed base).
