Analysis and Treatment of Jamming Problem of Main Bolt of VVER Reactor Pressure Vessel
摘要
Abstract
Through the analysis and treatment of the jamming problem of the main bolt of the reactor pressure vessel of Unit 4 in a nuclear power plant during the equipment manufacturing process,this paper explores the feasibility of receiving as is through simple polishing after the screw hole is damaged due to the jamming problem.The analysis results show that the bolt hole can be accepted as is by strength calculation when the damage is not serious.From the perspective of supervision management,it provides theoretical support and practical guidance for the subsequent prevention and treatment of pressure vessel bolt jam.关键词
