Nuclear Reactor Coolants - Robert B. Laughl

2016-8-3 · The two major types of water-cooled reactors are light water reactors (PWR) and boiling water reactors (BWR). Both use light (normal) water, but with slightly differing cooling mechanisms. In a BWR, the water turns into steam in the reactor core and is then pumped directly to the turbines that power electrical generators.

Breeder reactor - Wikiped

2019-9-4 · A breeder reactor is a nuclear reactor that generates more fissile material than it consumes. Breeder reactors achieve this because their neutron economy is high enough to create more fissile fuel than they use, by irradiation of a fertile material, such as uranium-238 or thorium-232 that is loaded into the reactor along with fissile fuel. Breeders were at first found attractive because they
