摘要： PROBLEM TO BE SOLVED: To solve problems in a periodical inspection of a nuclear reactor such that the period of the periodical inspection becomes long because a fuel handling machine installed on the upper part of the reactor core is used mainly for refueling and transfer of fuel assembly and cannot be used for the periodical inspection, thereby requires the improvement of the availability factor of the nuclear reactor.
SOLUTION: At a periodical inspection of a nuclear reactor, a floating stand 7 is put on the surface of the reactor water aside from a fuel handling machine. The floating stand 7 is connected to a foxed floor 5A of the nuclear reactor with a flexible connector 8 or 13 which is extendable or rotatable. By controlling the flexible connector 8 or 13 with a controller 12, the floating stand 7 can be moved desired position and direction on which an inspector stands to perform refueling and maintenance inspection at the same time.
