Description

Technical Field

[0001] The invention relates to the technical field of cutting the mouth of a spent fuel storage tank, in particular to a device for cutting the mouth of a spent fuel storage tank. Background Art

[0002] The high temperature gas-cooled reactor uses graphite-coated fuel balls as fuel elements and helium as coolant. It has the advantages of good safety, high power generation efficiency and good economy. It has been listed as one of the fourth-generation reactor development types by the International Nuclear Energy Agency. Since the fuel elements of the high temperature gas-cooled reactor are different from those of the pressurized water reactor nuclear power plant, the spherical spent fuel elements removed from the core need to be stored in suitable spent fuel storage tanks. In order to reduce the manufacturing cost of the spent fuel storage tanks, the spent fuel storage tanks are designed as thin-walled containers. In order to prevent the radioactive gases generated by the decay of the spent fuel during storage from escaping into the external environment, the boundary line between the tank plug and the tank mouth needs to be welded and sealed.

[0003] The welding quality requirements for the tank plug and the tank mouth are high, requiring the weld to be complete, the annular seam plane to have no obvious warping, the welding position to be accurate and to meet the sealing requirements. However, in the existing welding technology, the quality requirements of the weld cannot be fully guaranteed, and there are also cases where the welding quality is unqualified. For unqualified welds, it is necessary to replace the tank plug with a new one for re-welding. Therefore, it is necessary to cut the weld between the tank plug and the tank mouth.
