This pressurized water nuclear reactor, developed at the Knolls Atomic Power Laboratory, is designed to have increased energy density and to operate for 40 years without refueling.

2018年12月3日 · Bechtel designed the Columbia-class reactor, known as S1B. The Navy sought and received roughly $190 million in research and development funding for the Columbia reactor in the Pentagon fiscal 2019 budget bill signed in September.

Naval reactors of the United States Navy, listed alphabetically by ship type.

The A1B reactor is developed by the United States Navy for the Gerald R. Ford -class nuclear-powered aircraft carriers. Each ship will be powered by two A1B reactors.

To provide power to the electric drive, the Columbia class nuclear propulsion plant relies on a life-of-the-ship reactor core—called S1B—that is planned to remain in service without refueling, almost 10 years longer than current U.S. Navy nuclear reactors.

其装备美国最新研制的S1B型核反应堆，该反应堆在S9G反应堆基础上提升了功率密度，也极大可能继承S9G反应堆的自然循环能力，使“哥伦比亚”级核潜艇在中低速航行时不使用主循环水泵，降低机械噪声。
