PURPOSE:To secure cooling ability of the cooling system of an auxiliary machine during a periodical inspection by providing connecting pipes which can supply cooling water between respective cooling systems of at least two or more of the auxiliary machine. CONSTITUTION:The lower half of an attached drawing shows a cooling system of a turbine auxiliary machine and the upper half shows the cooling system of an atomic reactor auxiliary machine. Connecting pipes 50A, 50B are provided between two cooling systems. When heat exchangers 1B, 1C in the cooling system of the turbine auxiliary machine stop their operation during the periodical inspection of an atomic powder plant, and cooling ability of the cooling system of the turbine auxiliary machine is short, a part of cooling water flowing into a cooling heat exchanger 1A of the turbine auxiliary machine flows into the heat exchangers 31A-31C of the atomic reactor auxiliary machine through a pipe 50A, when connecting valves 50A, 50B are opened. Cooled cooling water flows into the cooling system of the turbine auxiliary machine through a connecting pipe 50B and sucked into a cooling water pump 2A and supplied to an air conditioner for cooling. By circulating cooling water in such manner, deficiency of cooling ability of the heat exchanger 1A is supplemented and cooling ability of the cooling system of the turbine auxiliary machine is secured.
