The design covers an essentially complete plant. clear power plants operate in the U.S., supplying one fifth of that country's electricity. Fewer large, new Generation III advanced light water reactor plants are being built than expected. for 18 month fuel cycle). Most common nuclear reactors are light water reactors (LWR), in which light water (ordinary water) is used as a moderator as well as the cooling medium. Close. The pressurized water reactor (PWR) is a type of nuclear reactor used to the generate electricity and propel nuclear submarines and naval vessels. ALWR - Advanced Light Water Reactor. [2] Fig.1 shows the Koeberg nuclear power station, which has two pressurized water reactors.
