The S2G designation stands for S Submarine platform 2 Second generation Nuclear reactor core core designed by the contractor G General Electric was the contracted designer An S2G was the initial power plant of USS Seawolf SSN 575 USS Seawolf SSN 575 . This was one of three sodium cooled fast reactor s ordered for the Seawolf program at the same time as three PWR units were ordered to support the USS Nautilus SSN 571 USS Nautilus SSN 571 program In each case, one reactor was land based for training and research, one intended for installation on a submarine, and one spare. The land based unit corresponding to S2G was S1G reactor . Persistent superheater problems on Seawolf caused the superheaters to be bypassed, resulting in mediocre performance. This and concern for the dangers posed by liquid sodium coolant led to the PWR type being selected instead as the standard US naval reactor type, and the S2G on Seawolf was replaced by the spare S2Wa reactor from the Nautilus program.

The S1G designation stands for S Submarine platform 1 First generation Nuclear reactor core core designed by the contractor G General Electric was the contracted designer This nuclear reactor was constructed by General Electric as a prototype for the USS Seawolf SSN 575 USS Seawolf SSN 575 submarine. It was a liquid metal cooled reactor using pure sodium to cool the core instead of water, because the higher temperature of liquid sodium compared to pressurized water enabled the production of more superheated steam in the Steam generator nuclear power steam generators . This resulted in a more efficient thermal cycle, yielding more Horsepower Shaft horsepower shaft horsepower for a given reactor size. The reactor design had problems because of limited operating temperature constraints. The major disadvantage of this concept was the ignition of sodium when exposed to air. S1G was used for testing and training. Eventually a sodium leak resulted in a fire, and the facility was shut down. In the meantime, the S1W reactor S1W and S2W reactor S2W pressurized water reactor s, conceived for the USS Nautilus SSN 571 USS Nautilus SSN 571 , had demonstrated their superior reliability.

The A3W designation stands for A Aircraft carrier platform 3 Third generation Nuclear reactor core core designed by the contractor W Westinghouse Electric 1886 Westinghouse was the contracted designer The reactor was intended for use aboard USS John F. Kennedy CV 67 USS John F. Kennedy . This four nuclear reactorreactor design was intended to reduce the cost involved in the construction and operation, as compared with the USS Enterprise CVN 65 Enterprise and its eight nuclear reactors. Early in the construction, the United States Secretary of the Navy had the plans changed to save money, and fossil fuel boilers were installed on the Kennedy. Because the plans for the ship did not include a funnel ship funnel , the funnel on the Kennedy protrudes out from the ship at an angle. The return to nuclear power for carriers came with the Nimitz class aircraft carrier Nimitz class s A4W reactor s two reactor per ship design. While the two reactor configuration, with each core providing a much greater thermal output, is relatively less expensive than earlier designs, the power plant still represents about half the total cost of the ship.
