Proposals of new basic concepts on safety and radioactive waste and of new High Temperature Gas-cooled Reactor based on these basic concepts

A new High Temperature Gas-cooled Reactor, namely the New HTGR, which can satisfy the conditions required is proposed based on the new basic concepts on safety and radioactive waste. It is indicated that the New HTGR with about 4 MW/m3 average power density and an YSZ stabilized fuel can response to social requirements for safety and environmental conservability against radioactive wastes, industrial requirements for economy, uranium resource sustainability and application diversity, and national requirements for non-proliferation and environmental protection from emitting carbon dioxide.
