发明名称 SEALING METHOD BETWEEN LIQUID METALLIC SODIUM PIPING AND HEAT RESERVING MATERIAL
摘要 PROBLEM TO BE SOLVED: To enable normal preheating, to prevent the degradation of a heater, to prevent a wasteful use of electric power, to prevent reduction in insulation, and to prevent diffusion of aerosol. SOLUTION: This method seals the clearance relative to a heat reserving material in the penetrating part of a wall and a floor of liquid metallic sodium piping where an electric heater 4, a sodium leakage detector and thermometer wells 5, 6 are laid in the clearance with the heat reserving material arranged on the periphery by penetrating through the heat reserving material. At this time, the clearance between the wall, floor side piping and the heat reserving material is sealed more than a position where an electric heater 4 leader line, the thermometer wells 5, 6, a piping support device 8 and the like penetrate through the heat reserving material.
