1. A coolant loop system carrying a fluid coolant for a nuclear reactor, the system comprising:
a heat exchanger configured to transfer heat from the reactor to the fluid coolant;
a heat extractor;
a hot leg exiting from the heat exchanger and entering the heat extractor;
a cold leg exiting the heat extractor and entering the heat exchanger;
a purifier and heat sink system joined to the hot leg and the cold leg so as to permit the fluid coolant to flow directly from the hot leg into, and flow into the cold leg from, the purifier and heat sink system, wherein the purifier and heat sink system is joined to the hot leg and the cold leg on opposite sides of the heat extractor so that the purifier and heat sink system does not flow into the heat extractor.
