Editing D1G reactor

{{More citations needed|date=February 2022}}
The '''D1G reactor''' was a [[prototype]] [[United States Naval reactor|naval reactor]] designed for the [[United States Navy]] to provide [[electricity generation]] and [[Nuclear marine propulsion|propulsion]] on [[warships]].  The D1G designation stands for:

* D = [[Destroyer]] platform
* 1 = First generation [[Nuclear reactor core|core]] designed by the contractor
* G = [[General Electric]] was the contracted designer

This prototype [[nuclear reactor]] was constructed for the [[United States Department of Energy]]'s Office of Naval Reactors as part of the Naval Nuclear Propulsion Program.  The reactor was built by General Electric and operated by the [[Knolls Atomic Power Laboratory]] at the Kesselring Site Operation in [[Milton (town), New York|West Milton, New York]].  It was used for testing components and as a training tool for the Nuclear Power Training Unit.  The reactor operated from 1962 to 1996, when it was shut down in March of that year.  It was later defuelled, with the [[pressure vessel]] eventually removed in 2002.

The containment structure — which housed both the primary (nuclear reactor) and secondary (steam plant) systems — is referred to as the "DIG-ball" due to its unique shape: a [[Horton sphere]]. The [[sphere]] was originally constructed by Chicago Bridge and Iron Works to house the [[liquid metal cooled reactor]] of {{USS|Seawolf|SSN-575|6}}, with the [[dome]] designed to contain a liquid sodium explosion.

In January 2022, a radioactive tank that was used to support the D1G reactor was transported from West Milton, New York to Wampum, Pennsylvania for disassembly.  The load was 213 feet long and weighed 294 tons.<ref>{{cite news | first=Michael | last=Levenson | title='Superload' Lumbers Across Pennsylvania, Two Lanes Wide and as Big as Two Whales | date=14 January 2022 | newspaper=The New York Times | url=https://www.nytimes.com/2022/01/14/us/superload-truck.html | access-date=15 January 2022}}</ref>
