Abstract

PURPOSE: To obtain a high responsibility, by means of consitituting an alloy storage gutter, a separating panel, a control system of a back up gas, and a plurality of nozzles.
CONSTITUTION: When in a fuel exhange time, a fuse seal alloy 11 is melted, and the liquid surface of the inside and the outside of a reactor are balanced by means of compressing a cocered gas and a back-up gas of the reactor respectively. When the covered gas pressure is raised, argon gas is supplied to pipes 23, a nozzle 25 and a gutter 10 from a supplying header by means of functioning by an unit 22 of control pressure. When the change of the covered gas pressure is rashly changed, the flow change of argon gas becomes large, but because of so many numbers of nozzles, it gets off without the flow change per one nozzle, and the wave of the freeze surface is never generated. By such means, the back-up pressure is allowed to follow-up and change to a rach change of the covered gas of the reactor, and the local waving of the alloy liquid surface is prevented.
