From Wikipedia, the free encyclopedia

The A1B reactor is a nuclear reactor being designed for use by the United States Navy to provide electricity generation and propulsion on warships. The A1B designation stands for:

• A = Aircraft carrier platform
• 1 = First generation core designed by the contractor
• B = Bechtel is the contracted designer

Initial plans for the CVN 78 ("CVN(X)" or "CVN-21") carrier program include a two-reactor complex intended to replace the A4W reactor design used on the Nimitz class carriers.
