The A1W reactor is a prototype nuclear reactor used by the United States Navy to provide electricity generation and propulsion on warships. The A1W designation stands for: A = Aircraft carrier platform; 1 = First generation core designed by the contractor; W = Westinghouse was the contracted designer

The NRF is a United States Department of Energy-Naval Reactors facility where three nuclear propulsion prototypes A1W, S1W and S5G were located. It is contractor-operated for the government by Fluor Corporation through their subsidiary, Fluor Marine Propulsion, LLC, which also operates Bettis Atomic Power Laboratory and Knolls Atomic Power ...

Nov 2, 2023 · IDAHO FALLS, Idaho – The Naval Reactors Facility turned over the aircraft carrier first design by Westinghouse reactor prototype (A1W) to the Department of Energy Office of Environmental...

Mar 14, 2023 · As the Navy’s need for nuclear-powered surface ships evolved, the A1W nuclear prototype was built at the Naval Reactors Facility to test new technology. The S1W and A1W facilities were shut down in 1989 and 1994, respectively.

Oct 17, 2024 · At the Aircraft Carrier 1st Generation Westinghouse (A1W) project, workers are using a sponge-blasting technology to remove paint containing polychlorinated biphenyls that was applied to facility equipment and components.

A1W - As nuclear technology evolved, the U.S. Navy adapted nuclear power to surface vessels. To support this effort, in 1956 Westinghouse started constructing the first nuclear-powered surface ship prototype, A1W, which consisted of two pressurized water reactors powering a …

May 31, 2009 · As a result, NRF was home to three nuclear propulsion prototypes: A1W, S1W and S5G. From the early 1950s to the mid-1990s, NRF was where the U.S. Navy sent sailors for training while it tested and refined nuclear fuels and reactor designs. Nearly 40,000 Navy personnel learned to operate surface and submarine nuclear power plants.

a1w The AlW plant at the Naval Reactors Facility in Idaho, the land-basd prototype for the A2W used on the CVN-65 Enterprise, the first nuclear-powered aircraft carrier, was placed in standby in...

A1W facility, a prototype for Enterprise aircraft carrier, had a dual-pressurized water reactor plant in a steel hull replica. It was the first facility with two reactors powering the propeller...

Following WWII, the U.S. Navy contracted the Westinghouse Electric Corporation to create a prototype for a pressurized water reactor (PWR) submarine plant. In 1955, this reactor, named S1W, sustained a 66-day continuous full power simulation of sailing around the world.
