ABSTRACT:
A passive safety system for a nuclear reactor coolant system including a water storage tank, a heat exchanger positioned within the water storage tank and connected to the hot leg, and a core make-up tank having a tank inlet connected to the heat exchanger and a tank outlet connected to a selected location of the nuclear reactor coolant system. Upon the occurrence of an abnormal condition, water flows by natural circulation from the hot leg through the heat exchanger so that heat may be transferred to the water in the water storage tank, and thereafter flows through the core make-up tank and into a selected location of the nuclear reactor coolant system to provide cooling for the reactor core.
