Subsidies for nuclear in 2010: $2.5 B http://www.eia.gov/analysis/requests/subsidy/
With nuclear generating about 800 TW-h, that comes to about 3.2 $/MW-h.
The subsidy in Price-Anderson depends on your estimate of the frequency of multibillion-dollar catastrophes. In 2008, the CBO figured it at $600,000 per reactor-year. (But other estimates put it several times higher.) With 100 reactors in the fleet, that comes to about 0.1 $/MW-h. Meanwhile, the NRC is charging an annual licensing fee of $4.8 million per reactor.
The loan guarantee program was designed to *not* subsidize nuclear. The Vogtle deal has been hanging fire for years because the government and the owners haven't agreed on how big a fee to charge to cancel out the subsidy. (For the solar and wind loan guarantees, the government ate the fee.)
