Description

Monju is a prototype FBR cooled by liquid sodium in Japan. This plant is designed that spilt sodium is stored in the lowermost rooms in the event of large sodium spill accidents. Installation of heat sink in the storage room can lower the temperature of spilt sodium and is effective to mitigate the thermal damage to the structural concrete and to reduce the emission of hydrogen gas. Monju will place small alumina balls of 60ton as a heat sink material in each storage room in order to improve the countermeasure systems against the sodium leak accident. After the installation of the heat sink, a temperature of the floor concrete of the storage room can be kept less than 150degC and falling temperature of stored sodium brings to suppress the dissociation of sodium hydride and the hydrogen concentration in the upper air region of the room can be kept less than 4% sufficiently.
