摘要:
The present invention is used to reduce thermal load itself, being the cause to generate stress, which develops near liquid surface in a nuclear reactor wall and to contribute to further improvement of safety. A partition member (5) is arranged above a coolant liquid surface (9) in an annulus space (3) between a reactor vessel (1) and a guard vessel (2), a low-temperature gas is circulated through the annulus space above the partition member to cool down, the gas is circulated through the annulus space from under the coolant liquid surface to the partition member, and the high-temperature gas heated under the coolant liquid surface is used to raise the temperature above the coolant liquid surface.

A power supply device includes: a power factor correction circuit which includes a capacitor and which corrects a power factor of power; a DC-DC converter which includes a switching element and which steps up or down an output voltage of the power factor correction circuit; a control unit; and a voltage detection unit which detects a voltage of an input side of the power factor correction circuit. The control unit controls the switching element such that an output voltage of the DC-DC converter is gradually reduced when stopping an operation of the DC-DC converter in a normal state in which the voltage detection unit does not detect a voltage lower than a predetermined value. When the voltage detection unit detects a voltage lower than the predetermined value, the control unit immediately turns off the switching element to stop the operation of the DC-DC converter.
