Abstract

PURPOSE: To shut off a gap and prevent a coolant from gushing out when the pressure in a reactor rises, by providing cut-off annular seals in an opening consisting of a recess on a flange and a recess on a sealed surface of a plug.
CONSTITUTION: A coolant gush preventing unit 3 is integrally provided in the opening consisting of the recess 13 on the flange and the recess 12 of the plug of the nuclear reactor vessel so that the preventing unit 3 extends along the circumference of the sealed surface 14 of the plug. The coolant gush preventing unit 3 comprises two rings having cut-off openings 31, 32 which are located away from each other. When the pressure in the reactor rises sharply, the rings 11 are deformed outward and tightly fitted on the surface of the flange and the sealed surface of the shield plug to prevent the coolant from gushing through the gap between the flange and the plug.
