D2G reactor

The D2G reactor was a naval reactor used by the United States Navy from 1962 to provide propulsion and electricity generation on warships.<ref name="A"/> Ships powered by the reactor were decommissioned at around the end of the 20th century. The D2G designation stands for:

• D = Destroyer platform
• 2 = Second generation core designed by the contractor
• G = General Electric was the contracted designer

History

Two of these nuclear reactors were installed on each of the Bainbridge, Truxtun, California, and Virginia classes of guided missile cruisers. The only nuclear-powered cruiser in the United States Navy not equipped with a D2G reactor was the world's first nuclear cruiser, the USS Long Beach (CGN-9), which used two C1W reactors.<ref name="A">Template:Cite web</ref>

It is known that USS Bainbridge's reactors were refueled three times, and USS Truxtun's were refueled twice.<ref name="A"/>

Operation

Each D2G reactor was rated for a maximum thermal output of Template:Convert, with two steam turbines which drove two shafts, each generating between Template:Convert.<ref name="B">Template:Cite web</ref><ref name="A"/> Each reactor was Template:Convert long, Template:Convert wide, and weighed Template:Convert. One reactor was located in the aft of the hull, the other in the fore. The reactors of the California class ships were replaced by Template:Convert D2W reactorsTemplate:Clarify in the early 1990s.<ref name="A"/>
