Maybe a bit of history but the following numbers worth a look. This is published in June, 2008. Dolar is appreciated since then and commodity prices have collapsed.

"What do all these cost increases mean for the cost of building a new generating
plant?"
"No one knows precisely. It’s difficult to get consistent and trustworthy numbers about plant costs, both because they are commercially sensitive and because the assumptions behind them vary greatly. The numbers reflected on the slide come from a variety of sources and include different assumptions about, for example, location or exactly what facilities are included in the estimate. To take one example: Two recent nuclear procurements in South Carolina and Georgia produced cost estimates of $5,100 and $6,400 per kW, respectively, for the same technology. We have been told that most of the difference may be due to different uses of Allowances for Funds Used during Construction – AFUDC."
