Boiling water reactor employs. Boiling water reactors (BWR) are a type of nuclear reactor that use light water (ordinary water, as opposed to heavy water) as their coolant and neutron moderator.They are the second most used reactor for nuclear power generation in the world, next to the pressurized water reactor (PWR)—with 75 in operation as of 2018. (d) MW Heat is produced by nuclear fission in the reactor core, and this causes the cooling water to boil, producing steam. E. infinity, A. gas cooled Answer: Option B Solution (By Examveda Team) A boiling water reactor (BWR) uses demineralized water as a coolant and neutron moderator. Heat is produced by nuclear fission in the reactor core, and this causes the cooling water to boil, producing steam.
