OK, after some googling it seems it's "not more than €12.5 billion" or "between €10 and 12 billion" for two reactors with a 1200 MW output each. Seems more reasonable, but it still shows that nuclear power has very considerable capital costs.

Of course, that also means that getting really cheap credit radically improves the competitiveness of nuclear power. I didn't find out what the interest is on the loan (it's supposed to be "highly preferential"), but the terms are pretty sweet: repayment begins when the plant is commissioned, and will last for 21 years. According to another source, it's a 30-year loan.

By the way, good news Orban is moving away from Putin, and good that he got this pretty sweet deal despite that. If the plant is ever built, that is.

Peak oil is not an energy crisis. It is a liquid fuel crisis.
