S2Wa reactor

S2Wa reactor

The S2Wa reactor is a naval reactor used by the United States Navy to provide electricity generation and propulsion on warships. The S2Wa designation stands for:

* S = Submarine platform
* 2 = Second generation core designed by the contractor
* W = Westinghouse was the contracted designer

After pressurized water reactor technology had proved its superiority in the S1W and S2W applications, the USS "Seawolf" (SSN-575) had her S2G liquid metal cooled reactor replaced using spare S2W components. During the conversion, the steam turbines in the powerplant were also re-bladed to utilize saturated, rather than superheated, steam.
