【摘要】：为分析AP1000核电厂中正常余热排出系统(RNS)的低压注射性能,本文保守假定低压注射工况下反应堆冷却剂系统的压力和阻止堆芯补水箱水位继续下降的最小注射流量要求恒定不变。在此基础上,结合RNS低压注射管路的布置信息和正常余热排出泵的性能曲线,计算分析了RNS在向反应堆冷却剂系统进行低压注射的工况下分别从安全壳内置换料水箱和装料池两个水源吸水时该系统的低压注射性能(主要借助注射流量和注射可持续时间两个性能参数进行衡量)。通过上述计算分析,本文不仅验证了AP1000RNS低压注射功能设计的可靠性,同时也定量给出了两个低压注射水源的实际注射容量。
[Abstract]:In order to analyze the low pressure injection performance of (RNS), a normal waste heat removal system in AP1000 nuclear power plant, In this paper, it is conservatively assumed that the pressure of the reactor coolant system under the condition of low pressure injection and the minimum injection flow rate to prevent the water level of the core replenishment tank from continuing to decline are constant. On this basis, combined with the layout information of RNS low pressure injection pipeline and the performance curve of normal waste heat discharge pump, The low pressure injection performance of RNS under the condition of low pressure injection into reactor coolant system is calculated and analyzed when RNS absorbs water from two sources of water source built in the containment tank and loading tank respectively (mainly with the help of injection flow rate and injection). The shoot duration is measured by two performance parameters. Through the above calculation and analysis, this paper not only verifies the reliability of AP1000RNS low pressure injection function design, but also quantitatively gives the actual injection capacity of two low pressure injection sources.
