Excel-based tube-sheet diagram generation method for nuclear steam generator heat exchange tube inspection

Abstract

The invention discloses an Excel-based tube plate diagram generating method during nuclear power steam generator heat exchanging pipe detection. The method includes the steps of S1, building a coordinate system in the preset area of an Excel worksheet, wherein each cell of the preset area corresponds to one coordinate; S2, collecting the heat exchanging pipe information of the preset loop of a steam generator; S3, inserting icons representing heat exchanging pipes in the corresponding cells of the coordinate system to generate an initial tube plate diagram; S4, importing coordinate lists of the heat exchanging pies which need to be tracked and detected; S5, marking the icons, corresponding to the coordinates in the coordinate lists, in the cells. The method has the advantages that the tube plate diagram is generated automatically according to the imported coordinate lists of the heat exchanging pies which need to be tracked and detected, the process is simple, a large amount of repeated work is reduced, and work efficiency is increased.

Description

technical field [0001] The invention relates to the field of detection of heat exchange tubes of steam generators in nuclear power plants, and more specifically relates to an Excel-based method for generating tube-sheet diagrams during detection of heat exchange tubes of nuclear power steam generators. Background technique [0002] In addition to ensuring the normal and safe operation of the units, nuclear power plants also face periodic safety review PSR (HAD103-11) and deferred operation review (the design life of in-service nuclear power plants is mostly 30-40 years). In the review work, the review of safety elements of nuclear power plants is an extremely important review content. [0003] The safe operation of nuclear power plants is protected by three barriers: the first barrier - fuel pellets and cladding, the second barrier - a strong pressure vessel and a closed primary circuit system, and the third barrier - containment. For a typical three-circuit nuclear power u...
