AP1000平准化发电成本计算及影响因素分析

Study on the Levelized Cost of Electricity of AP1000 Nuclear Power Technology and Influence Factors

采用平准化发电成本(EGC)的计算方法来研究AP1000核电技术的经济性,并运用两种不同计算方法分别计算三门核电及其他堆型核电站的EGC。根据计算结果分析AP1000核电技术的经济性特点,并定量计算核电站建设周期、经济寿期、负荷因子对AP1000核电站EGC的影响。分析结果表明,目前AP1000技术平准化发电成本与已运行核电站相比偏高,这是由国产化率较低、规模效应与学习效应不明显导致。另外,建设周期、经济寿期、负荷因子等因素均会直接影响到发电成本,相关研究可以为提高核电经济性提供参考。

This paper used the calculation method of the levelized cost of electricity （ EGC ） to study the economic of AP1000 nuclear power technology. The EGC of Sanmen reactor power other reactor power stations were calculated by two methods. It also makes quantitative analysis on the economic characteristics of AP1000 nuclear power technology, and discusses the influence of construction period, economic life, load factor and other factors on the EGC of AP1000 nuclear power. The analysis result shows that the EGC of AP1000 technology is higher than other reactor power, because the localization rate is low, the scale effect and learning effect is not obvious. The construction cycle, economic life, load factor and other factors will directly affect the cost of electricity. Relevant research studies can provide a reference for improving the economics of nuclear power.
