Abstract
Provided are a safety protection system facility 43 outputting a normal actuating signal S1 in a case where the safety protection system facility 43 controls actuation of a unit provided in a nuclear facility to a safe side based on an abnormality detecting signal output at the time of occurrence of an abnormality in the nuclear facility, and where this causes the unit to be actuated normally, and a CCF countermeasure facility 44 outputting a CCF-case actuating signal S2 actuating the unit to a safe side in a case where the CCF countermeasure facility 44 determines from output results of the abnormality detecting signal and the normal actuating signal S1 that the unit is not actuated normally at the time of occurrence of the abnormality in the nuclear facility.
