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
boilerA 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

A turbine hall is typically extremely
loudIn 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...
and hot.
In nuclear power plants
Boiling water reactorThe 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
containedA 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.
