The A4W reactor is a naval reactor used by the United States Navy to propel warships and generate onboard electricity.
The A4W designation stands for:
- A = Aircraft carrier platform
- 4 = Contractor's fourth core design generation
- W = Westinghouse, the contracted designer
These nuclear fission pressurized water reactors (PWRs) were jointly designed by Bettis Atomic Power Laboratory and Knolls Atomic Power Laboratory[1] and built by Westinghouse Electric Company. Their reactor cores are expected to operate for about 20 years.[1] The only ships to use these nuclear reactors are the Nimitz class supercarriers, which have two reactors rated at 550MWt each. These each generate enough steam to produce a 100 MW electricity supply plus 140,000 shaft horsepower (104 MW).[2]
