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. It has been in development since 1998. The A1B designation stands for: * A = Aircraft carrier platform * 1 = Contractor's first core design * B = Bechtel Marine Propulsion Corporation is the contracted designer 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. 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 watch standing requirements and a significant decrease of required maintenance. == References == 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「A1B reactor」の詳細全文を読む スポンサード リンク
