A1B reactor

The A1B reactor is a nuclear reactor being designed for use by the United States Navy to provide electricity generation and propulsion for the Gerald R. Ford–class aircraft carriers.[1] It has been in development since 1998.[2]

The A1B designation stands for:[3]

Initial plans for the Gerald R. Ford–class carrier program include a two-reactor complex intended to replace the A4W reactor design used on the Nimitz-class carriers. The new A1B reactor plant is a smaller, more efficient design that provides approximately three times the electrical power of the Nimitz-class A4W reactor plant.[4] The modernization of the plant led to a higher core energy density, lower demands for pumping power, a simpler construction, and the use of modern electronic controls and displays. These changes resulted in a two-thirds reduction of watchstanding requirements and a significant decrease of required maintenance.[5] The ship is powered by two Bechtel A1B nuclear reactors, each capable of producing 300 megawatts of electricity, triple that of Nimitz-class reactors.[6]
