摘　　要：为解决600 MW示范快堆(CFR600)事故分析和工况设计中的实际问题,自主开发了钠冷快堆系统程序FR-Sdaso,其建模范围包括堆芯、一回路、二回路、三回路、四回路和事故余热排出系统,主要物理模型包括点堆模型、单通道堆芯热工模型、多区钠池模型、四区蒸汽发生器模型等核岛设备或部件分析模型,汽轮机、凝汽器、给水加热器、除氧器等常规岛设备采用集总参数模型,泵、阀门、管道及控制体等采用通用模型。对程序进行了初步验证,结果表明,FR-Sdaso程序可用于分析全厂瞬态工况及超功率、失流、失热阱等典型事故过程。目前,FR-Sdaso程序已用于CFR600的设计和安全分析。To solve actual problems in the accident analysis and working condition design of the 600 MW demenstration fast reactor(CFR600),the sodium-cooled fast reactor(SFR)system code FR-Sdaso was developed,which could be used to model the reactor core,primary system,secondary system,tertiary system,quadruple system and the decay heat removal system of the SFR.The physical models can be divided into three categories:The models for nuclear island equipment including point reactor model,single-channel core thermal model,multi-zone sodium pool model and four-zone steam generator model,etc.,the lump parameter models for conventional island equipment,including turbine,condenser,feed water heater,deaerator,etc.,and the general models for pump,valve,pipe and control volume.Preliminary V&V work for FR-Sdaso was conducted,and the results show that FR-Sdaso can be used to analyze the transient conditions of the whole plant and typical SFR accidents such as overpower,loss of flow,and loss of heat sink.FR-Sdaso was used in the design and safety analysis of the CFR600.
