核电厂设备冷却水系统调试研究

Study on Commission of Equipment Cooling Water System in Nuclear Power Plants

设备冷却水系统(RRI)是核电厂重要辅助系统,其用户覆盖核岛及核电厂的外围设施系统(BOP),在正常运行工况和各种事故运行工况下均必须确保运行稳定。因此,在RRI的调试中必须对其相关设备性能和逻辑功能逐一验证。本文对RRI的波动箱试验、电动泵试验、流量调整试验、自动列间切换试验过程中出现的问题进行分析判断,重点分析流量分配方法及计算扩孔数据的方法和流量孔板装反影响流量的机理,并提出解决途径。

Equipment Cooling Water System(RRI) is an important auxiliary system of nuclear power plants, and its users cover the fields of nuclear island and the periphery of nuclear power plant facilities systems(BOP)system. It must be ensured that the Equipment Cooling Water System can operate stably under normal operation condition and various accident conditions. Hence, equipment performance and logic functions of RRI must be verified one by one. This paper focuses on fluctuating tank test, motor pump test, flux adjustment test, and automatic switch test of different serials, analyzes and judges the problems occurred in the tests, and discusses the flux distribution method, hole-digging calculation method and the influence on the flux by the reverse installation of flow orifices, and the way to solve these problems.
