I work in the electric biz (AEP), and I can promise you this: there will be no new nukes in the foreseeable future. All this about construction starting by decade's end is just wishful thinking on the part of the nuke biz. I wish it were so, but it IS NOT happening. I am not in that business so this is probably way off base, but from what I have read, it appears to me that Grand Gulf, Mississippi, has some chance for expansion from one reactor to two.
I did a Google search on Grand Gulf and found what I think is an interesting web page that has some pretty recent information, including a pro-nuclear power rally in Mississippi: http://www.aaenvironment.com/NewNukes3.htm
Here's a photo from the webpage:
The buzz I've heard, and I'm not sure how to conferm it, is that quietly eight nuke construction permits have already been filed. Some several years back.
The part of the bill I like is the ethynol tax breaks and requirements. While it is going to mean more cost at the pumps it keeps the farmers happy producing a renewable resource and industrial construction types (like me) busy building the plants.
