摘要
文章分析了反应堆热功率计算过程,以及文丘里管差压式流量计与超声波流量计在三门核电主给水流量测量中的差异。针对流量测量精度对反应堆热功率计算不确定度的影响开展了分析探讨,并总结了国外核电厂的小幅功率提升的研究成果和实施方式。研究分析表明,通过提高给水流量测量精度进行小幅度功率提升是完全可行的,同时可以在保证核电厂安全、稳定运行的前提下提高经济效益。
Based on the flow measurement for main feedwater in Sanmen Nuclear Power Plant and summary of the research results and implementation mode of recapture power uprates(MUR) in foreign nuclear power plant, effects of measuring accuracy on reactor thermal power calculation and uncertainty are analyzed. Analysis indicates that MUR by improving the measurement accuracy of main feedwater is feasible, which will increase the economic returns without influencing the safe and stable operation of plant.
