Editing D2G reactor

The '''D2G reactor''' was a [[United States naval reactors|naval reactor]] used by the [[United States Navy]] from 1962 to provide  [[Nuclear marine propulsion|propulsion]] and [[electricity generation]] on [[warship]]s.<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 [[Nuclear reactor core|core]] designed by the contractor
* G = [[General Electric]] was the contracted designer

== History ==
Two of these [[nuclear reactor]]s were installed on each of the [[Bainbridge class cruiser|''Bainbridge'']], [[Truxtun class cruiser|''Truxtun'']], [[California class cruiser|''California'']], and [[Virginia class cruiser|''Virginia'']] classes of [[guided missile]] [[cruiser]]s. 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)|USS ''Long Beach'' (CGN-9)]], which used two [[C1W reactor]]s.<ref name="A">{{cite web|last1=Lobner|first1=Peter|title=60 Years of Marine Nuclear Power: 1955 – 2015, Part 2 - United States|url=http://www.lynceans.org/wp-content/uploads/2015/12/USA-60-yrs-of-marine-nuc-power-v2.pdf|website=Lyceans.org|date=December 2015}}</ref>

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

==Operation==
Each D2G reactor was rated for a maximum thermal output of {{convert|148|MW}}, with two steam turbines which drove two shafts, each generating between {{convert|30000|and|35000|shp}}.<ref name="B">{{cite web|title=US Nuclear Propulsion|url=https://www.forecastinternational.com/archive/disp_old_pdf.cfm?ARC_ID=1838|date=18 August 2000|url-access=registration}}</ref><ref name="A"/> Each reactor was {{convert|37|ft}} long, {{convert|31|ft}} wide, and weighed {{convert|1400|t}}. 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 {{convert|165|MW|adj=on}} D2W reactors{{Clarify|date=December 2022|reason=See talk page}} in the early 1990s.<ref name="A"/>
