根据ＨＦＥＴＲ（高通量工程试验堆）的安全分析报告，参照核电厂的安全法规，经过认真分析高通量工程试验堆在多年的运行中所发生的故障、事件和事故，将其安全功能划分为反应性控制、堆芯冷却、堆芯热导出、一回路压力边界完整性、放射性控制５个关键安全功能，根据这５个关键安全功能，选择了能够全面评估反应堆安全状态、代表高通量工程试验堆各安全功能的一组主特征参数。
According to the safety analysis report of HFETR (High Throughput Engineering Test Reactor), with reference to the safety regulations of nuclear power plants, after careful analysis of faults, incidents and accidents occurred in the operation of high-throughput engineering test reactors over many years, safety functions are divided According to the five key safety functions, the five key safety functions of reactor control, core cooling, core thermal derivation, primary pressure boundary integrity and radioactivity control were selected to fully evaluate the reactor safety status and represent the high-throughput A set of main characteristic parameters of each safety function of engineering test bed.
