METHOD FOR MONITORING RESTRICTIVE CONDITION FOR OPERATION OF COOLANT SYSTEM IN HEAVY WATER REACTOR AND APPARATUS USING THE METHOD

摘要

The present invention provides a method and an apparatus to monitor a restrictive condition for operating a coolant system in a heavy water nuclear power plant, capable of ensuring security for operating a heavy water reactor by setting alarms. The method comprises the following steps: measuring the pressure of a coolant inlet header and a coolant outlet header; calculating the pressure difference between the pressure of the coolant inlet header and the coolant outlet header to generate information about the pressure difference between the coolant inlet header and the coolant outlet header by loop path; and displaying the information about the calculated pressure difference between the coolant inlet header and the coolant outlet header by loop path in real time.
