ABSTRACT:
Radioactive emissions by reason of primary-liquid-to-secondary-liquid leakage in the steam generator of pressurized water reactor power plants are reduced by a demineralizer in the discharge from the blowdown tank and also by transmitting blowdown venting vapor to the condenser. For major failures resulting in power blackout an auxiliary turbine is provided. This turbine is connected to be energized by vapor (steam) by-passed from the main steam line. The auxiliary turbine drives the pumps which pump the cooling water for the condenser. The steam which drives the auxiliary turbine is also discharged to the condenser. The condensed water flows back into the steam generators where it is discharged through the blowdown tank.
