Regarding bare plant costs, some recent figures apparently for overnight capital cost (or Engineering, Procurement and Construction - EPC - cost) quoted from reputable sources but not necessarily comparable are:
EdF Flamanville EPR: EUR 3.3 billion/$4.8 billion, so EUR 2000/kW or $2900/kW Bruce Power Alberta 2x1100 MWe ACR, $6.2 billion, so $2800/kW CGNPC Hongyanhe 4x1080 CPR-1000 $6.6 billion, so $1530/kW AEO Novovronezh 6&7 2136 MWe net for $5 billion, so $2340/kW KHNP Shin Kori 3&4 1350 MWe APR-1400 for $5 billion, so $1850/kW
FPL Turkey Point 2 x 1100 MWe AP1000 $2444 to $3582/kW
NEK Belene 2x1000 MWe AES-92 EUR 3.9 billion (no first core), so EUR 1950 or $3050/kW UK composite projection $2400/kW NRG South Texas 2 x 1350 MWe ABWR $8 billion, so $2900/kW
On the assumption that overall costs to the utility are twice the overnight capital cost of the actual plants, then the figures quoted above give: SCEG Summer 2 x 1100 MWe AP1000 $2200/kW
There are several possible sources of variation which preclude confident comparison of overnight/EPC capital costs - eg whether initial core load of fuel is included. Much more obvious is whether the price is for the nuclear island alone (Nuclear Steam Supply System) or the whole plant including turbines and generators - all the above figures include these. Further differences relate to site works such as cooling towers as well as land and permitting - usually they are all owner's costs. Financing costs are addi
