Zusammenfassung:	PROBLEM TO BE SOLVED: To vaporize coolant by heating in a separator and separate coolant steam from unvaporized neutron absorbers in the separation and removal of neutron absorbers from reactor coolant. SOLUTION: The distillation and separation into deionized water as coolant and a concentrated boric acid solution as neutron absorbers and the deaeration of oxygen from deionized water containing oxygen as raw coolant are carried out under a lower pressure generated by a vacuum pump, and the thermal energy required for the separation process is released into a cooling water circuit connected to an intermediate cooling water system of a nuclear installation from the separator or a recuperative condenser or a gas cooler attached to it. The cooling water circuit is connected to closed heat pump circuits via a heat exchanger and heat pump circuits encapsulating coolant absorb most thermal energy in the heat exchanger, raises a temperature level through the mechanical compression of coolant steam, and utilize the thermal energy in a separator such as a boric acid tower and an deaeration tower or other heat load.
