Analysis and Improvement of Throttling Orifice of NPP RCV System
-
摘要: 使用理论分析与计算机模拟的方法对某在建M310核电厂中化学和容积控制系统(RCV)的限流孔板RCV001/002/003DI进行计算;分析原设计中存在的振动剧烈和噪音超标的问题,验证使用对接焊四级限流孔板替代承插焊单长孔孔板的设计合理性。该项改进已在某在建和已运行的核电厂中得到实施和验证。Abstract: We analyzed and simulated the throttling orifice RCV001/002/003 DI of M310 NPP’s RCV System. The defect in the original design of M310 has been found and optimized by using the step-orifice to reduce vibration and noise. This design change has been applied and verified by several NPPs which are either under construction or operation.
