Innovation of Steam Generator Pilot In-Service Inspection Management Strategy

In this paper, through comprehensive technology, combined with peer experience,from the manufacturing, operation, inspection technology to analysis, the strategy of pilot in-service inspection management is put forward. Comparing factory documents, historical data, operation conditions, and defect quantities, the typical representative steam generator（SG）is selected. The reasonable and feasible SG inspection plan is formulated, and has been examined and approved by the regulator. Continuous tracking inspection is carried out for the pilot SG, to provide technical reference for other similar components. According to the inspection results to optimize other SG inspection plan, it has reduced 63000 times of MRPC inspections, and shortened the critical path period of the outage by 60 days. It indirectly creates the economic benefits of ten million yuan for the enterprise, and provides new thoughts and methods for the supervision and management of other in-service inspection components.
