とを特徴とするオーバフロ管の予熱方式。In the reactor vessel overflow pipe of a liquid metal cooled reactor, an annulus space is created between the outer wall of the pipe and the inner surface of the heat insulating material to prevent the occurrence of extreme temperature differences between the upper and lower parts of the vertical pipe when the flow of fluid inside the pipe is interrupted. A preheating method for an overflow pipe characterized by combining circulation equipment for forced convection of the fluid inside the pipe with a preheating method using an electric resistance heater.
