Operation control device for FBR type reactor
Description
The device of this invention comprises a coolant recycling pump system in a coolant flow system of an FBR type reactor having the first coolant flow rate flow coast down characteristic for compensating the transient range of coolant temperature, flow rate, etc. upon reactor scram and the second coolant flow coast down characteristic for slowly compensating coolant temperature upon control rod insertion failure (ATWS) when requiring reactor scram. Further, there is provided a scram detection systems for selecting the first coolant flow rate flow coast down characteristic upon reactor scram and the second coolant flow rate flow coast down characteristic upon failure of control rod insertion. In this operation control device, the operation can be controlled from the full power to the step of reaction with no boiling of the coolants even in a case of ATWS, while no abrupt thermal shocks are applied to the structural materials upon usual scram.
