S6W Advanced Fleet Reactor
The S6W Advanced Fleet Reactor that powers the SEAWOLF Class is revolutionary in the military sense -- quietness and more efficient performance. It is not a radical design from a safety standpoint. The reactor is a typical Naval pressurized water reactor. The advanced fleet reactor has been installed in the S8G prototype plant for testing, and the S8G prototype plant with the Advanced Fleet Reactor will operate exactly as it has for the past 12 years. That reactor went critical in March 1994 and operated well. Putting the new reactor in a prototype affords the opportunity to operate it before introduction into the fleet, run it harder than in the fleet to determine its peak performance, and test its long-term properties. For the shipboard plant, the reactor core was loaded March 1995 and the ship's pre-commissioning crew began operating reactor plant systems.
