摘要
核电站安全壳打压试验是机组大修期间的绝对关键路径工作,试验执行质量影响机组大修的总体进度。其中泄压速率作为决定安全壳打压试验工期的重要因素,通过建立核电站安全壳内外结构仿真模型,对25 kPa/h泄压速率时安全壳结构的安全性进行分析,提出泄压速率提升的理论依据,同时将模拟数据与缩尺安全壳模型进行对比验证,旨在为安全壳打压试验全面优化提供技术指导。
The containment pressure test of a nuclear power plant is an absolutely critical path work during unit overhaul period.The practical quality of containment pressure test affects the overall progress of unit overhaul,and the pressure relief rate is an important factor determining the test duration.This paper establishes a simulation model of internal and external structures of the nuclear power plant′s containment,studies and analyzes safety of the containment structure at a pressure relief rate of 25 kPa/h,and proposes a theoretical basis for improving pressure relief rate.Moreover,the simulation data are compared and verified with the scaled containment model,aiming to provide technical guidance for the comprehensive optimization of containment pressure testing.
