ABSTRACT:
A pressurized-water reactor coolant treatment system continuously removes a portion of the coolant circulating in the main coolant loop and passes it through a gas separator and a rectification column, among other equipment, and returns the coolant to the main coolant loop. By passing the removed coolant first through the rectification column and thereafter through the gas separator and providing means for controllably shutting off the separator and bypassing the removed flow around the gas separator for passage of the flow from the rectification column back to the loop, it is possible to subject the coolant to both rectification and degassing when the coolant requires such treatment, and when the coolant does not require degassing to shut down the gas separator and put it out of operation. Other features are included.
