Abstract

Korea Atomic Energy Research Institute (KAERI) is developing an accelerator driven system called HYPER (Hybrid Power Extraction Reactor) for the transmutation of nuclear waste. HYPER program is within the framework of the national mid and long-term nuclear research plan. KAERI is aiming to develop the system concept and a type of roadmap by the year of 2000. Some major design features of HYPER system have been developed. On-power fueling concepts are employed to account for the rapid drop of core reactivity. In order to increase the proliferation resistance, whole TRU without any actinide separation will be transmuted in the HYPER system. The long-lived fission products such as 99Tc and 129I will be destroyed using the localized thermal neutrons separately in the HYPER. A hollow cylinder-type metal fuel (TRU-Zr) has been chosen because of its high compatibility with pyrochemical process. Pb-Bi is adopted as a coolant and spallation target material. The heat removal system is designed based on 3 loop concept. 1 GeV 6mA proton beam is to be provided for HYPER. HYPER is to transmute about 380 kg of TRU a year and produce 1000MWth power. The support ratio of HYPER is believed to be 5 ~ 6.
