Zusammenfassung:A method and system (40) for an alternate energy removal path for a reactor pressure vessel (RPV) of a light water reactor. A pair of manually operated containment isolation valves (36), one located inside and one located outside of primary containment (7), are used to open and close a steam extraction line (30) that is fluidly coupled between the RPV and a heat sink (32). The heat sink is located outside of primary containment. A source of external electrical power is not required to operate the system or perform the method.
