摘　　要：为了评价CPR1000核电汽轮机热力性试验的试验质量和试验结果的可信度,对CPR1000核电汽轮机热力性能试验中诸多测量参数以及热耗率的不确定度进行了分析探讨,并给出相应的计算公式。以红沿河2#机1 118 MW核电汽轮机热力性能试验为例,进行了主蒸汽压力、主蒸汽湿度、主蒸汽流量、主给水压力、主给水温度、排汽压力、发电机出力和热耗率不确定度的计算。最终计算出热耗率的不确定度为0.505%,该结果表明试验质量和试验结果的可信度均较好。In order to evaluate the quality of the thermal performance test for CPR1000 nuclear powersteam turbine and the credibility of the test result, The uncertainties of many measurement parameters andthe heat rate of CPR1000 nuclear power steam turbine are analyzed, and the reference formulas are list.Taking the test in HONGYANHE nuclear power plant unit 2 as an example, The uncertainties of mainsteam pressure, main steam moisture, main steam flow, main feedwater pressure, main feedwater temper-ature, exhausted steam pressure, the generator output and heat rate are calculated. Finally, the uncer-tainty of the heat rate is 0.505 %. The result shows that both quality of the test and the credibility of thetest result are better.
