That's interesting - the costs, I mean.
I wonder why it's a different story in the UK, where this has just been published in their 'The Independent' - note the comment about there being no 'public subsidy':
"The Government today dropped plans to build a 10-mile barrage across the Severn estuary to generate "green" electricity from tides.
An official study said there was currently no "strategic case" for investing public money in such a scheme, the costs of which could run to more than £30 billion, although it said it could be reconsidered as a longer-term option in the future.
But the Department of Energy and Climate Change paved the way for new nuclear power plants at eight sites - Bradwell, Essex; Hartlepool; Heysham, Lancashire; Hinkley Point, Somerset; Oldbury, South Gloucestershire; Sellafield, Cumbria; Sizewell, Suffolk and Wylfa, Anglesey.
The coalition Government has already said it will give the go-ahead to companies who want to build new nuclear plants, provided there is no public subsidy involved, despite the Lib Dems opposing new nuclear power stations in opposition. "
