|Design||Company||Reactor type||Generating capacity||Key features||Proposed locations|
|Advanced Passive 1000
|Westinghouse||Pressurized water reactor
||1,150 MWe or enough electricity to power a city with a population of about 650,000
||Shuts down in an emergency without requiring operator action for 72 hours. About half of the 440 nuclear plants worldwide operate using Westinghouse technology, according to the company.||Duke Energy’s William Lee site in Cherokee County, S.C.; FPL's Turkey Point site in Homestead, Fla.; Progress Energy’s site in Levy County, Fla.; Progress Energy Carolinas’ Harris site in Wake County, N.C.; South Carolina Electric & Gas V.C. Summer site in Fairfield County, S.C.; Southern Nuclear Operating Company’s Vogtle site in Burke County, Georgia; Tennessee Valley Authority’s Bellefonte site in Jackson County, Ala.
|Economic Simplified Boiling-Water Reactor
|GE-Hitachi Nuclear Energy||Boiling water reactor||1,520 MWe or enough electricity to power nearly 1 million homes||If water in the reactor vessel drops below normal levels, steam is condensed back into water and activates a gravity-driven cooling system. If radioactive material is released, it’s trapped in the containment building rather than escaping into the environment.||Detroit Edison Company’s Fermi site in Monroe County, Mich.; Dominion’s North Anna site in Louisa County, Va.|
|Evolutionary Power Reactor
|Areva Nuclear Power||Pressurized water reactor||1,650 MWe or enough electricity to power 1.5 million homes||Areva’s design uses less uranium than its predecessors, has lower power generation costs, and it's double-containment building can withstand a military or commercial airplane crash, according to the company. In case of emergency, one of four redundant safety systems kicks in.
||AmerenUE's Callaway site in Callaway County, Missouri; PPL's Bell Bend site in Luzerne County, Pa.; UniStar Nuclear Energy's Nine Mile Point site in Oswego, New York; Unistar's Calvert Cliffs site in Calvert County, Maryland.|
|U.S. Advanced Pressurized Water Reactor
|Mitsubishi Heavy Industries Ltd.||Pressurized water reactor||1,700 MWe or enough electricity to power 875,000 homes||Design modified for U.S. market: Size of plant, which includes four steam generators, reduced by 20 percent. Mixed oxide fuel, which is made from reprocessed nuclear fuel waste, may be an option.||Luminant's Comanche Peak site in Somervell County, Texas|
