Reduced moderation water reactor
From Wikipedia, the free encyclopedia
The reduced moderation water reactor (RMWR) is a proposed type of light water moderated nuclear power reactor, featuring some characteristics of a fast neutron reactor. As of 2007 it is under active development in theoretical studies, particularly in Japan.
Even in generation II PWRs, the neutron spectrum is not fully thermalised. The goal of RMWR research is to depart further from the thermal neutron spectrum in order to achieve a breeder ratio of slightly greater than 1, so that after the initial fuel charge no enrichment of the uranium input to the fuel cycle is required.
The RMWR concept is dependent on nuclear fuel reprocessing in order to achieve its objectives.
