I hope there's not a test on this. It was interesting reading.

From Wikipedia:

"Nuclear Power Training Unit
Nuclear Power Training Unit (NPTU), one of which is also located at Naval Weapons Station Charleston, has two decommissioned submarines, USS Daniel Webster (MTS-626) and USS Sam Rayburn (MTS-635). These moored training ships have their missile compartments removed, but have fully operational S5W reactor power plants.

Two land-based reactor prototypes are based at the Knolls Atomic Power Laboratory, Kenneth A. Kesselring Site Operation, in Ballston Spa, New York. These are the MARF/S7G and the S8G Trident prototypes. (The S8G core has now been replaced with the S6W reactor core). At one time, two additional prototypes were operational: D1G and S3G.

[edit] NPTU History
Knolls Atomic Power Laboratory in New York has the longest operational history of NPTUs. However, two other sites also provided operational training during the Cold War.

From the early 1950s to the mid-1990s, Naval Reactors Facility (NRF) in Idaho trained nearly 40,000 Navy personnel in surface and submarine nuclear power plant operations with three nuclear propulsion prototypes — A1W, S1W and S5G.[7]

Concurrently, from 1959 until 1993, over 14,000 Naval operators were trained at the S1C prototype at Windsor Locks, Connecticut."

And

"Daniel Webster was decommissioned on 30 August 1990 and stricken from the Naval Vessel Register the same day. She was converted to a moored training ship (S5W Prototype facility) by the Charleston Naval Shipyard at Charleston, South Carolina. Upon completion and designated MTS-626, she was towed up river to her permanent berth at the Naval Nuclear Power Training Unit Charleston."

The Rayburn originally had a S5W reactor.

More from Wikipedia:

"Reactor designations
Each nuclear reactor design is given a three-character designation consisting of a letter representing the type of ship the reactor is intended for, a consecutive generation number, and a letter indicating the reactor's designer.

Ship types:

"A" - aircraft carrier
"C" - cruiser
"D" - destroyer
"S" - submarine
Contracted designers:

"B" - Bechtel
"C" - Combustion Engineering
"G" - General Electric
"W" - Westinghouse

ahhh ha! Well that answers that question

Comment by Jeff B. on March 29, 2010 at 1:36pm

Good question - that I don't know....

Comment by David on March 29, 2010 at 1:18pm

Yes, I know that they are the only places now in use! But I guess I need to more specific in my question.
Today's Navy uses three or four different types of reactors!
Do both sites have all of the reactors or do have just certain types at both locations?

Comment by Jeff B. on March 29, 2010 at 11:09am

As far as I know - that is the only 2 locations

Comment by David on March 29, 2010 at 10:51am

Are all prototypes at GC and Ballston Spa?

Comment by Jeff B. on March 29, 2010 at 9:39am

Great idea - thanks for the info

Comment by GP on March 29, 2010 at 8:55am

Jeff, yes he is MM.
Also, I started a new group called "Ballston Spa" where we can list whatever info we come across. This way others who are not interested aren't subjected to weave through the messages on the Nuke group.

Comment by KS Dad on March 26, 2010 at 8:37pm

Chris B / Jeff B,
My son's a MM in power school due to graduate 09-Jul. He's interested in going to Ballston Spa. Keep posting info as you find it, as I'd be interested. Heard there might be a 3-7 month wait to go to Prototype.
