The invention relates to a reactor pressure vessel and a supporting device for an outlet nozzle of the pressure vessel. The pressure vessel comprises a cylinder and an in-pile component arranged in the cylinder, wherein at least one outer nozzle is arranged on the side wall of the cylinder. The supporting device comprises a cylindrical body which can be arranged between the in-pile component and the cylinder in a sleeving manner; an outer flange is arranged on the outer ring of one end of the cylindrical body and can be hung at the upper end of the cylinder; an inner flange is arranged on theinner ring of the other end of the cylindrical body and is used for supporting a supported flange on the outer wall of the in-pile component; and a second circulating hole corresponding to the position of the outer nozzle is formed in the side wall of the cylindrical body, the cavity of the cylindrical body runs through the second circulating hole and the inner nozzle and is communicated to the outer nozzle after an inner nozzle is arranged in the second circulating hole. The inner nozzle and the in-pile component are separately arranged on the supporting device, so that the assembly and separation of the in-pile component cannot be influenced by the inner nozzle, the workload is reduced, and the work efficiency is improved.
Description
technical field [0001] The invention relates to the field of nuclear power, more specifically, to a reactor pressure vessel and a supporting device for the outlet nozzle of the pressure vessel. Background technique [0002] The reactor pressure vessel in the related art includes a cylinder and a hanging basket arranged in the cylinder, an outer nozzle is arranged on the side wall of the cylinder, an inner nozzle is installed on the hanging basket, and the inner nozzle extends laterally into the cylinder Inside the outer nozzle on the side wall. [0003] When the hanging basket needs to be hoisted out for maintenance, the inner nozzle needs to be removed separately, otherwise, the inner nozzle will affect the hanging out of the hanging basket. The disassembly process of the inner nozzle increases the workload of maintenance and reduces the work efficiency. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a reacto...
