摘要: Plan and status of research development (R&D) were described on coated fuel particle (CFP) compacts for the core small-sized high-temperature gas-cooled reactor (HTGR) HTR50S at second step phase I (second HTR50S). Specifications existing CFPs high burnup (HTR50S2-type-CFPs) adopted as specifications CFPs, to reduce R&D. HTR50S2-type-CFPs fabricated based technology developed in High Temperature Engineering Test Reactor (HTTR) project. The first irradiation test is now being carried out. In addition, R&D compact with packing fraction planned, because volume UO2 kernel whole HTR50S2-type-CFP rather smaller than that HTTR-type-CFP. We would aim complete proof nuclear/thermal design integrity fuel, feeding back results R&Ds each other. we describe outline plans II practi...
