Keywords:Micro reactor

MHI develops a mobile micro reactor adopting a high thermal conductor for the core material. The reactor transfers the core heat without coolant that removes heat from the core. With simplified system adopting the all solid reactor concept, the reactor eliminates the coolant accident events, and it contributes to the nuclear reactor safety. We introduce the preliminary heat transfer analysis for the reactor accident, focused on temperature behavior in the reactor, nuclear reactor vessel and mobile container.
