装置。When the reactor is isolated, the steam generated by the reactor is guided to the turbine,
A reactor isolation cooling system for driving a pump by the turbine and injecting condensate storage tank water into the reactor core, and guiding reactor generated steam from the turbine upstream piping to a residual heat removal system heat exchanger for condensation; In the residual heat removal system steam condensation mode injected into the reactor core, the piping connecting the upstream side of the turbine and the residual heat removal system heat exchanger is partitioned off with a double shutoff valve, and between the shutoff valves, there is a leak 1-f piping and By arranging valves and traps, and periodically discharging leaked steam and water from the shutoff valve, it is possible to prevent pressure and temperature increases in the piping downstream of the shutoff valve during normal reactor operation. Steam cutoff device.
