There has been an interpretation ruling on loan guarantees for 100% of the loan to a maximum of 80% of the total project for carbon dioxide reducing energy projects The loan guarantees make nuclear energy the cheapest option for energy. It pretty much guarantees that all 30 nuclear reactors that are in the planning stages in the USA will be built.
If a reasonable climate change bill is passed (likely in 2009) then the combination will cause a boom in nuclear power building in the United States. The amount of nuclear power would be projected to triple by 2030. 100-150 of the new larger reactors would be the primary source of any new power needs (along with more wind, solar and biomass and conservation and efficiency). The climate change bill will likely ratchet up the cost of coal plants and cause them to be shutdown and replaced over 20-30 year timeframe.
