More Information
Summary:The present invention provides an alternative circulation cooling method for an emergency core cooling system that, even if the emergency core cooling system does not operate normally, can prevent the implementation of containment vessel venting by suppressing a rise in pressure and temperature in the containment vessel, and can suppress the implementation of dry-well venting even if containment vessel venting needs to be performed, as well as a nuclear power plant that is capable of the same. An alternative circulation cooling method for an emergency reactor core cooling system is performed at a nuclear power plant that includes an RHR system and a MUWC system. The method includes: connecting the downstream side of an RHR heat exchanger to the upstream side of a MUWC pump, and cooling water from a suppression chamber using the RHR heat exchanger and performing nuclear reactor injecting or containment vessel spraying using the MUWC pump.
