Abstract:
A nuclear reactor cooling system with passive cooling capabilities operable during a loss-of-coolant accident (LOCA) without available electric power. The system includes a reactor vessel with nuclear fuel core located in a reactor well. An in-containment water storage tank is fluidly coupled to the reactor well and holds an inventory of cooling water. During a LOCA event, the tank floods the reactor well with water. Eventually, the water heated by decay heat from the reactor vaporizes producing steam. The steam flows to an in-containment heat exchanger and condenses. The condensate is returned to the reactor well in a closed flow loop system in which flow may circulate solely via gravity from changes in phase and density of the water. In one embodiment, the heat exchanger may be an array of heat dissipater ducts mounted on the wall of the inner containment vessel surrounded by a heat sink.

Claim (Index 17):
The system according to  claim 2 , wherein the closed flow loop includes:\n inlet steam piping fluidly coupling the heat exchanger to an enclosed top portion of the reactor well which prevents escape of the steam to an environment inside the containment vessel; and outlet condensate piping fluidly coupling the heat exchanger to an enclosed top portion of the cooling water tank; wherein the enclosed reactor well and cooling water tank form an integral part of the closed cooling water flow loop.
