The turbine hall
, generating hall
or turbine building
is a building that is a part of any steam cycle or hydroelectric power plant which houses a number of components vital to the generation of electricity from the steam that comes from the boiler
A boiler is a closed vessel in which water or other fluid is heated. The heated or vaporized fluid exits the boiler for use in various processes or heating applications.-Materials:...
, or from the water coming from the reservoir. The components in the turbine hall typically comprise of the turbines, moisture separators, reheaters, electric generator, and/or exciter
Exciter may refer to:* The low-power RF stages of a radio transmitter* A component of an electrical generator* Exciter bulb, a light source for reading the optical soundtrack on motion picture film; see sound-on-film* Exciter , audio effect unit...
A turbine hall is typically extremely loud
In common use, the word noise means any unwanted sound. In both analog and digital electronics, noise is random unwanted perturbation to a wanted signal; it is called noise as a generalisation of the acoustic noise heard when listening to a weak radio transmission with significant electrical noise...
In nuclear power plants
Boiling water reactor
The boiling water reactor is a type of light water nuclear reactor used for the generation of electrical power. It is the second most common type of electricity-generating nuclear reactor after the pressurized water reactor , also a type of light water nuclear reactor...
s present unique challenges since the water going through the turbines is radioactive. This means that the turbine hall has to be slightly contained
A containment building, in its most common usage, is a steel or reinforced concrete structure enclosing a nuclear reactor. It is designed, in any emergency, to contain the escape of radiation to a maximum pressure in the range of 60 to 200 psi...
and much unique maintenance must be performed.
A typical plant will house one high pressure turbine and two low pressure turbines.
