Medium Pressure Safety Injection with Accumulators. As with current pressurized water reactors (PWRs), accumulators are required for large loss-of-coolant accidents (LOCAs) to meet the need for higher initial makeup flows to refill the reactor vessel lower plenum and downcomer following RCS blowdown. The gas pressure forces open check valves that normally isolate the accumulators from the RCS. The accumulators are sized to respond to the complete severance of the largest RCS pipe by rapidly refilling the vessel downcomer and lower plenum. 1, record 1, English, - medium%20pressure%20safety%20injection
