ABSTRACT:
Apparatus is described for supplying injection liquid to the primary coolant pump shaft seals in a pressurized water nuclear reactor system. The injection liquid is the resultant mixture of liquid extracted from both the upstream and downstream sides respectively of the regenerative heat exchanger in the chemical and volume control system of the plant. The temperature of this liquid is controlled by regulating the liquid proportions admitted in the respective flow streams.
