中文摘要: |
根据EPR(欧洲压水堆)核电堆芯仪表管嘴封头的结构、功能及验收标准,结合台山核电一期工程建设经验,提出了堆芯仪表管嘴封头装拆工艺,详细阐述了装拆方法及注意事项,并进行密封试验和密封检验措施的有效性实验验证,最后进行试验位置、弹簧压缩量与允许压升数据统计及分析,并在台山核电站工程中进行了装拆工艺的验证. |
英文摘要: |
This thesis presents the assembly and removal technology of instrumentation core nozzle closure through the introduction of the structures,functions and acceptance criteria of instrumentation core nozzle closure in EPR (European pressurized water reactor) nuclear power plant and the construction experiences in Taishan Phase I.This thesis expounds the strict assembly and removal methods and precautions,states the tightness tests and verifies the validity via some measures.Finally,it analyzes the data statistics and test positions,spring compressing values and permissible raise pressure data,and verifies that assembly and removal technology is feasible and correct during Taishan nuclear power plant construction. |
