Areva has gotten a €8 billion order for two 1600 MW reactors in China. €4 billion each. The same reactor ordered a few years ago by Finland costed €3 billion. It's very clear that rising costs for steel, copper, cement and especially things like turbines and generators are driving costs upwards. These cost, unlike those for oil and gas, should go back down eventually as supply catch up with demand.
Anyway, we are talking about €2500 per kW now. That's almost $3750 per kW. Not good, even though the horrid cost in dollars is due to the continuing weakening of that currency. If you want to see a silver lining, this should be good for US reactor exports. Funny though that the US might well be manufacturing reactors for export, while not affording to install them at home...
But this doesn't make nuclear less competitive, as costs have soared across the board, making wind mills and coal plants more expensive at the same time.
Irony of ironies, gas fired power generation has become more competitived against these three other forms of generation.
edit:
It seems they have upped the power to 1700 MW, so you get €2350 per kW or about $3500 per kW.
