ABSTRACT:
Jet pumps and a feed water sparger are disposed in a reactor pressure vessel incorporating a core. A first feed water pipe supplies a portion of feed water to the jet pumps as their driving water. A second feed water pipe connected to the first feed water pipe supplies the remaining portion of the feed water to the feed water sparger. A first feed water heater is disposed in the first feed water pipe downstream of a connecting point of the first feed water pipe and the second feed water pipe. An amount of extracted steam introduced into the first feed water heater is controlled on the basis of a difference in the temperature between feed water flowing through the first feed water pipe and the feed water flowing through the second feed water pipe.
