Abstract

The Korea Atomic Energy Research Institute (KAERI) has been performing accelerator driven system related research and development, called HYPER, for the transmutation of nuclear waste and energy production through the transmutation process. The HYPER program is being performed within the framework of the national mid- and long-term nuclear research plan. KAERI is aiming to develop a system concept and type of roadmap by the year 2001 and complete the conceptual design of the HYPER system by the year 2006. Some major design features of the HYPER system have been developed. The burnable poison concept is being developed to keep the core reactivity swing less than 10%. In order to increase proliferation resistance, a pyro-chemical process is employed for the separation. The trade-off studies for fuel fabrication are being performed. A dispersion type fuel is believed to have advantages in terms of achieving high discharge burnup. The long-lived fission products such as Tc-99 and I-129 will be destroyed using localized thermal neutrons separately in the HYPER. A calcium hydride is employed as moderator. SSC-H (Super System Code-HYPER) is being developed to simulate the behaviour of coolant systems. The thermal hydraulic properties of Pb-Bi are implemented on the SSC-H. Design optimization of target and beam window is being performed using FLUENT and ANSYS computer codes. In addition, beam irradiation testing is performed to estimate the hardness of window material (9Cr-2WVTa) due to the proton using keV order accelerator. Beam diameter and window thickness are optimized based on the simulation results.
