Development of HTGR-GT power generation system 2. Recent status of international cooperative development program of GT-MHR (Gas-turbine modular helium reactor)

GT-MHR is a high effective nuclear power generating plant that combines a modular high temperature gas cooled reactor having passive safety characteristics with the direct cycle helium gas turbine. Fuji Electric is participating this project in cooperation with General Atomics of the U.S.A., the Russian Ministry of Atomic Energy, and Framatome of France, with the aim of the realization of GT-MHR. Fuji Electric, on behalf of GA, MINATOM, Framatome and Fuji Electric, introduces in this paper the outline of this project and the main system of the GT-MHR plant. (author)
