An AP1000 normal residual heat removal pump - one of the main devices in a normal residual heat removal system (RNS) in an auxiliary plant of an AP1000 nuclear power plant, has the following main features:
It extracts the heat generated at shutdown of a reactor coolant system. After the start-up of an automatic pressure system (ADS), it provides low pressure replenishment water from the feeding tank of a spent fuel pool cooling system (SFS) to RCS.
When needed it discharges the residual heat from refuelling water tank built in the containment.
After an accident it provides a long-term refuelling channel to RCS
Other features: shutdown purification, low temperature overpressure protection, spent fuel pool cooling
