The G low pressure mode is set. In this state, since the main saturation temperature is lower than that in the high pressure mode in which the condenser is operated, that is, since the temperature difference with the atmosphere is smaller, the amount of heat radiation is reduced, and the amount of steam for warming up is reduced. Can be reduced. In this state, the high-pressure steam condenser 5 is in a standby state.

From 20g / cm 2 G to the high pressure mode. By switching to the high pressure mode, the temperature inside the heat transfer tube rises as the saturation temperature rises, the surface temperature of the heat transfer tube rises, and the heat exchange amount increases. Thus, the steam flowing into the high-pressure steam condenser 5 can be quickly condensed. That is, when the control valve (CV2) is switched to the high pressure mode, the opening degree is reduced, and the internal pressure of the high pressure steam condenser is reduced to 20 kg / cm.
