乏燃料后处理厂抗震类管道包络性计算分析审评实践
The Selection Principle for Calculating the Envelopment of Aseismatic Pipeline in Spent Fuel Reprocessing Plant

乏燃料后处理厂存在大量抗震类管道，若全部进行详细力学计算，将耗费大量人力物力且无法满足工程进度要求。审评单位认为通过对安全分级、抗震要求、运行工况、管道规格、布置形式等方面进行分析，筛选出部分管道进行反应谱分析，另外采用确定性方法对执行安全功能或具有特殊要求的管道进行反应谱分析，其他管道进行简化计算的方法，是可行的，能够较好的解决计算效率问题、包络全部抗震类管道且保证管道地震工况下安全性。
Spent fuel reprocessing plant exists plots of aseismatic pipeline. If all the aseismatic pipelines are calculated detailed, it will cost many human and object resources. And it is unable to meet the project schedule requirements. In view of this, a method is provided that analysis through safety classification, seismic requirement, operating condition, pipeline specification and pipeline layout. Then some pipelines are selected for response spectrum analysis, other pipelines are calculated simplified. The evaluation units think the method is reasonable and feasible. In addition, the deterministic method is used for the detailed calculation of pipelines executing safety functions or with special requirements. This can better solve the problem of computational efficiency and ensure the safety of pipeline under seismic condition.
