The construction of China's nuclear power units has transitioned from the second generation and improved second generation to the third generation.Independent third generation nuclear power will be vigorously promoted at home and abroad.Calculating its life-cycle carbon emissions is a key in assessing its low-carbon competitiveness,which is still blank in China.This paper takes an independent third generation nuclear power demonstration project as the research object,conducts a detailed analysis of the entire industrial chain,selects the latest material and energy input data of the front end of the nuclear fuel cycle,the nuclear power plant construction and operation,and the back end of the nuclear fuel cycle,and combines the latest material and energy emission factors,calculating the life-cycle carbon emissions of the unit to be 10.04 gCO2-eq/kWh;if the back end of the nuclear fuel cycle is not considered,the value is 5.49 gCO2-eq/kWh.With the feedback of batch construction,the steady increase in utilization hours,and the reduction of the emission factor of national power grid,this value still has a significant room for decline.
