The OECD Nuclear Energy Agency’s (NEA's) calculation of the overnight cost for a nuclear power plant built in the OECD rose from about $1900/kWe at the end of the 1990s to $3850/kWe in 2009. In the 2020 edition of the Projected Costs of Generating Electricity joint report by the International Energy Agency (IEA) and the NEA, the overnight costs ranged from $2157/kWe in South Korea to $6920/kWe in Slovakia. For China, the figure was $2500/kWe. LCOE figures assuming an 85% capacity factor ranged from $27/MWh in Russia to $61/MWh in Japan at a 3% discount rate, from $42/MWh (Russia) to $102/MWh (Slovakia) at a 7% discount rate, and from $57/MWh (Russia) to $146/MWh (Slovakia) at a 10% discount rate.
The 2020 edition of Projected Costs of Generating Electricity makes the important point regarding LCOE: “At a 3% discount rate, nuclear is the lowest cost option for all countries. However, consistent with the fact that nuclear technologies are capital intensive relative to natural gas or coal, the cost of nuclear rises relatively quickly as the discount rate is raised. As a result, at a 7% discount rate the median value of nuclear is close to the median value for coal [but lower than the gas in CCGTs], and at a 10% discount rate the median value for nuclear is higher than that of either CCGT or coal. These results include a carbon cost of $30/tonne, as well as regional variations in assumed fuel costs.”

按照国内的说法，核电和太阳能成本差不多
