Light water reactor - ENS

Light water reactor - ENS

Collective term for all H2O moderated and cooled reactors; See 'boiling water reactor', 'pressurized water reactor' (H2O = "light" water, in contrast to D2O = "heavy" water). The light water reactor produces heat by controlled nuclear fission. The reactor core consisting of fuel and control elements is enclosed by a water-filled steel pressure vessel.

Introduction To Light Water Reactors

Introduction To Light Water Reactors

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. The use of ordinary water makes it necessary to use an enriched uranium fuel in order to maintain the criticality of the reactor along entire fuel cycle (e.g. for 18 month fuel cycle).
