Boiling Water Reactors

In Boiling Water Reactors (BWRs), water (primary coolant) is allowed to boil directly in the reactor core. The boiling water generates steam which is drawn away from the reactor and used to rotate the turbine, which in turn generates electricity via the generator.

While more cost-effective, boiling water reactors are .

A boiling water reactor produces heat using nuclear fission in the reactor core. This causes the water to boil and emit steam. The radiation from the nuclear fission is transferred to the water as it heats up, and the radiation is then emitted with the steam. 5.0 1 vote 1 vote Rate! Rate! Thanks

NUCLEAR 101: How Does a Nuclear Reactor Work? | Department .

May 19, 2020 · More than 65% of the commercial reactors in the United States are pressurized-water reactors or PWRs. These reactors pump water into the reactor core under high pressure to prevent the water from boiling. The water in the core is heated by nuclear fission and then pumped into tubes inside a heat exchanger.
