Previous generation of nuclear reactors in France were built for less than 2 billion euros (constant euro) per GW (sorry it's in french, you can see the numbers here http://i-tese.cea.fr/_files/LettreItese18/ECLAIRAGES/REP.pdf on page 10). There were 50 reactors of three types (900, 1300 then 1450 GW). If we had kept this technology instead of losing the know-how and developing a new program, we could certainly build 1500 GW for those 3T. Don't know if any other country ever achieved such economy scale on its civil nuclear program, maybe South-Korea as like France they have only one nuclear company, and even more reactors per sites of few different models.
