If you are a pre-1998 NUKE, you more than likely walked RICKOVER CIRCLE between the Control Rod Shaped building of Nuclear Power School and the Nuclear Field A School Building.
 
1993 saw the commandes combined to form Naval Nuclear power training Command. 
 
This is a unique 3.25" rectanguilar coin featuring the command logos for NFAS and NPS and a combined NNPTC logo. The back is a 3D representation of the command buildings and Rickover Circle. I've added the Glow in the DarkTri-Foil and Atomic Electrons symbols as well as the statement "Spread out and salute" because we all did that to make the officers salute more than once.
 
After I got commissioned and went back to NPS (9805), I laughed constantly as I watched the enlisted guys spread out. It was an awesome full circle.
