| 摘 要： | 热工水力瞬态分析软件TRANTH用于分析核电厂安全性，其中，考虑了两区质量守恒和能量守恒的关键模型之一稳压器模型可对稳压器安全阀、释放阀、电加热器、喷淋和相关系统进行模拟。在软件开发完成后需进行相关软件验证，故结合方家山核电厂1号机组稳压器安全阀流量试验数据和软件模拟结果，验证稳压器模型。结果表明，模拟计算结果与现场试验数据符合度高，模型精度满足工程设计要求。

| Abstract: | Nuclear power autonomous transient calculation software TRANTH is used to design and analyze nuclear power plant safety. Relevant verification needs to be done after the completion of software development. Energy conservation and mass conservation in gas region and liquid region are considered in pressurizer model (one of the key models). Safety valve, relief valve, electric heater, spray and related simulation are simulated. Combined with the flow test data and software simulation results of pressurizer safety valve of Fangjiashan Nuclear Power Plant 1# unit, the pressurizer model is verified. The results show that the simulation results are in good agreement with the field test data, and the accuracy of the model meets the engineering design requirements. |
