Boiling water reactor. Differs from the PWR primarily in that boiling takes place in the reactor itself. Comparable steam temperatures are possible at about 1000psi = 70 bar, about half the operating pressure of PWRs. Boiling water reactors employ bottom entry control rods because reactivity and moderator density is highest at the lower part of the core. This allows refuelling without removal of rods and drives. Ability to alter coolant recirculation rate gives excellent load following characteristics. Aside from its heat source, the BWR generation cycle is essentially similar to that found in fossil-fuelled power plants.
Boiling Water Reactor. A LWR where the water is allowed to boil in the core; the turbines are driven by the steam produced in the reactor core.
Boiling Water Reactor: an LWR in which the moderator/coolant is used directly to produce steam for electricity generation.
Boiling Water Reactor. A nuclear power reactor cooled and moderated by light water and fuelled by enriched uranium. The water is allowed to boil in the core to generate steam, which passes directly to the turbine.
Boiling water reactor. A common type of light water reactor (LWR), where water is allowed to boil in the core thus generating steam directly in the reactor vessel. (cf PWR)
