Editing S6G reactor (section)

== Design ==
The S6G reactor was designed by [[Knolls Atomic Power Laboratory]] under a contract with General Electric for use on the {{sclass|Los Angeles|submarine|0}} [[attack submarine]]s. The S6G reactor plant consists of the reactor [[coolant]], [[Steam generator (nuclear power)|steam generation]], and other support systems that supply steam to the engine room. The S6G is a 165 [[megawatt]] (MW) reactor driving two 26 MW [[steam turbine]]s.<ref>[http://www.world-nuclear.org/information-library/non-power-nuclear-applications/transport/nuclear-powered-ships.aspx World-nuclear.org]- Retrieved 2018-05-13</ref>

The ''Los Angeles''-class engine room also contains the steam turbines that generate electricity and drive the [[propeller]] shaft.<ref>[http://www.fas.org/man/dod-101/sys/ship/eng/reactor.html Nuclear Propulsion]</ref>  While exact specifications are classified, the S6G reactor can propel a ''Los Angeles''-class submarine at over {{convert|15|kn|km/h|lk=in}} when surfaced and over {{convert|25|kn|km/h}} while submerged.

The S6G reactor plant was originally designed to use the [[D1G reactor|D1G-2 core]], similar to the [[D2G reactor]] used on the {{sclass|Bainbridge|cruiser|0}} [[guided missile cruiser]].  All ''Los Angeles''-class submarines from {{USS|Providence|SSN-719}} on were built with a [[D2W]] core. The D1G-2 cores are being replaced with D2W cores when the boats are refueled.
