A1B reactor

The A1B reactor is a type of nuclear reactor designed for use in United States Navy aircraft carriers. The "A1B" designation follows the Navy's reactor naming convention:

• "A" signifies that it is used on an aircraft carrier.
• "1" indicates it is the first generation reactor of this type.
• "B" denotes the reactor was designed by Bechtel Corporation.

The A1B reactor is a pressurized water reactor (PWR) and is a significant advancement over previous naval reactors. Key features include increased power output, a simplified design, and extended core life, allowing for longer intervals between refueling overhauls. This extended core life significantly reduces downtime and maintenance costs for aircraft carriers equipped with the A1B reactor. The primary intended platform for the A1B reactor is the Gerald R. Ford-class aircraft carrier.
