S1W reactor

[1] The plant was the prototype for the power system of USS Nautilus (SSN-571), the world's first nuclear-powered submarine, which used the improved S2W reactor.

In May of that year, it began power operations, performing a 100-hour run that simulated a submerged voyage from the east coast of the United States to Ireland.

Large, exterior water spray ponds were used to dissipate the heat energy created in the facility into the air.

Trainees were graduates of the Naval Nuclear Power School in Bainbridge, MD, Mare Island, CA or Orlando, FL (all locations now closed).

The course of study lasted six months and consisted of a combination of classroom and closely supervised practical training.
