PROBLEM TO BE SOLVED: To obtain high reliability in response to common-cause failures and the like while decreasing the physical quantities of facilities in regard to safety facilities for a nuclear power plant. SOLUTION: These safety facilities for a reactor has a reactor pressure vessel 2 contained in a reactor containment vessel 1, main steam pipes 25 and water-supply pipes 26 connected to the reactor pressure vessel 2, water-pouring systems for pouring water into the reactor pressure vessel 2 separately and independently in divisions of them and power source facilities for feeding the equipment in the water-pouring systems separately and independently in each of the divisions. The power source facilities are used as power sources for feeding motor-operated valves 7a, 7b, 7c, 8a, 8b and 8c included in an isolation condenser system where the steam received in a condenser 6 from the main steam pipes 25 by way of a pipe 9 is condensed by the condenser 6 and the condensed water is returned to water-supply pipes 26 through the pipe 63 and the pipes 9 and 63.
