WebThis is the role of the moderator, a material made of light elements. The most usual moderator is ordinary water, also called light water (H 2O). If ordinary hydrogen 1H is replaced with its heavy isotope deuterium 2H (denoted also D), its compound with oxygen is called heavy water D2O. Heavy water is a more efficient moderator than light water, WebIt is also known as the light water graphite reactor (LWGR). As with a boiling water reactor (BWR), water boils in the fuel channels (at about 6.9 MPa) and steam is separated above … Find our more about us and our member companies. See details about our memb…
WebBoiling water reactor (BWR):A common type of light water reactor (LWR), where water is allowed to boil in the core thus generating steam directly in the reactor vessel. (cf.PWR) Breed:To form fissile nuclei, usually as a result of neutron capture, possibly followed by radioactive decay. WebThe Soviet designed RBMK is a hybrid graphite-moderated and water-cooled reactor only found in the former Soviet Union. The core is an assembly of graphite blocks, not unlike the core of a Magnox reactor, through which run pressure tubes containing the fuel.
