Temperature conditions in the RBMK spent fuel pool in the event of disturbances in its cooling mode

The problems of reprocessing and long-term storage spent nuclear fuel (SNF) at power plants with RBMK reactors have not been fully resolved so far. For this reason, are forced to search for new options the disposal fuel, which can provide least temporary SNF storage. One possible solutions problem is switch compacted in reactor pools (SFPs). As number assemblies (SFAs) SFPs increases, a greater amount heat released. In addition, no less important fact that place emergency FA discharging should be provided SFPs. paper presents results numerical simulation temperature conditions both discharging. Several types disturbances normal SFP cooling mode considered, including partial loss water exposure SFAs. was performed using ANSYS CFX software tool. Estimates were made time heating boiling point, as well cladding elements 650 °?. most critical observed compartment. obtained make it estimate personnel restore pool until maximum reached.
