Since 1986, the Nuclear Power Engineering Corporation has performed an investigative program on core performance improvements with the support of the Ministry of International Trade and Industry (MITI) in order to save uranium resources and to improve the capability of mixed-oxide (MOX) fuel loading for the next generation of light water reactors (LWRs). Both improvements were called for in the Perspective on Nuclear Energy for the 21st Century' presented by MITI. Its main features are as follows: (1) studies on uranium-saving factors (techniques) and the conceptual design of uranium-saving LWR cores; and (2) studies on the two types of MOX cores (100% MOX fuel-loaded core): high-moderation core (HMC) and low-moderation core (LMC). The HMC is designed to reduce the inventory of fissile plutonium, and the LMC is designed to reduce the fissile plutonium and uranium consumption for effective plutonium utilization. The conceptual designs of these cores were studied based on the advanced boiling water reactor (ABWR) and advanced pressurized water reactor (APWR).
