Abstract

Since mid 70’s, JAERI has been developing technologies for a dedicated partitioning process and transmutation system based on the double strata fuel cycle concept. The activities cover the development of a wet partitioning process, design study of an actinide burner reactor (ABR) and an accelerator-driven system (ADS), the development of nitride fuel cycle technologies, and basic research such as nuclear data, fuel property data measurements. Development of a high-intensity proton linac has been carried out under the Neutron Science Project of JAERl which aims at construction of a superconducting proton linac of 8-MW for a 5-MW spallation neutron source of neutron scattering facility and for ADS experimental facility. Since the autumn of 1998, JAERI and the High Energy Accelerator Research Organization (KEK) have been discussing a new proposal to pursue frontier science in particle physics, nuclear physics, materials science, life science, and ADS technology, using a high beam power new proton accelerator. Previously, KEK proposed the Japan Hadron Facility (JHF) that covers a broad range of science from high-energy physics to materials science, by using the primary and various secondary beams from the high power proton accelerator. The present new joint plan, temporarily called the “Joint Project”, is based on these two past proposals. It is also proposed that accelerator facility complex of this Joint Project be constructed at the JAERI site. The Joint Project is preparing the budget proposal for facility construction starting from FY2001.
