Reactor type
Boiling water (BWR)
46 BWR reactors operate worldwide today, with 46,335 MW net installed capacity in 8 countries. 14 more units have their operation suspended.
Water boils inside the reactor itself and the steam goes straight to the turbine. Fewer components than a PWR, at the cost of a radiologically controlled turbine hall.
