摘要
严重事故是指超出核电厂设计基准范围,并可能造成堆芯损坏的事故。严重事故相关培训对于核电厂操作人员至关重要。然而对于CANDU机组,由于全范围模拟机未考虑严重事故阶段的模拟,故操作人员缺乏严重事故相关的有效培训。为此,以图形化CANDU6全范围模拟机(简称“CANDU6-FSS”)为基础,将改造后的严重事故仿真MAAP5-CANDU模型集成到CANDU6-FSS上,完善严重事故阶段现象机理的模拟,从而使CANDU6-FSS具备了从稳态、设计基准事故甚至严重事故全工况的模拟,有效为核电厂相关工作人员尤其操作人员进行严重事故相关的培训演练和验证提供有效的手段,以提高操作人员和严重事故处理人员面对严重事故时的应急处理能力。
Serious accidents refer to accidents that exceed the design criteria of nuclear power plants and may cause damage to the core.Training for severe accidents is crucial for nuclear power plant operators.However,for CANDU units,due to the lack of consideration for simulating the severe accident stage in the full range simulator,operators lack effective training related to severe accidents.To this end,the graphical CANDU6 full-range simulator(CANDU6-FSS)was used as the basis,and the modified severe accident simulation model MAAP5-CANDU was integrated into the CANDU6-FSS to enhance the simulation of severe accident phenomena,thus enabling the CANDU6-FSS to simulate full-range conditions from steady-state,design-basis accidents to severe accidents,providing effective means for relevant plant personnel,especially operators,to train and validate their severe accident-related skills,thereby improving the emergency response capabilities of operators and severe accident response personnel in the event of a severe accident.
