摘　　要：单耗分析法是基于热力学第二定律以分析产品单耗结构作为降耗指标的能耗评价方法。核电系统遵循单耗分析方法,其能耗评价方式可以分为:标准燃料损耗化及附加单耗分布形式和标准煤耗化及其附加单耗分布形式,体现出不同标准燃料下的能耗分布状况。针对国内最新引进的第三代非能动压水堆AP1000机组进行拓展研究,在保证核电机组安全运行的前提下,提高堆芯对一回路换热温度等级,同时相应提高二回路汽轮机系统工质参数,对提高核电机组效率有显著作用;常规岛中减小蒸汽湿度,有助于降低回热系统能耗。Unit consumption structure of products is taken as the index of reducing the energy consumption by applying the methods of unit consumption analysis which is based on the second law of thermodynamics.The evaluation methods in the nuclear power system can be divided into two.One is the distribution of standard fuel consumption and its additional unit consumption.The other is the distribution of standard coal consumption and its additional unit consumption.Both of them reflect the energy consumption distribution under different fuel standard.The third generation AP1000 unit is taken as the object and the safe operation of nuclear units.The temperature level of heat transfer between the reactor core and nuclear circuit is improved and in the same time the medium parameters in the turbine system of conventional circuit is also improved,which improve the nuclear unit efficiency significantly.In addition,reducing the steam humidity in the normal island is conductive to reducing the energy consumption of regenerative system.
