I was reading this earlier today

, and some of the companies interactions seemed a little out of whack

by my memory. However, I did not want to trust my memory alone

with such vaunted posters as have already written here. So, I consulted with "a reliable source" as the person wishes to remain.
General Physics started a new division called General Technical Services (GTS) for HP and QA staff augmentation. GTS developed its own division for HP support called HP Technical Services and bought Fauth Associates which was a QA Services provider.
Some of the management of RAD Services left RAD when the other side of the business came under legal problems and joined HPTS. RAD Services went out of business and the Rad Services contracts were taken over by NSS including as well all the employee records.
GTS folded the HP and QA Group together becoming just General Technical Services without the divisions
GTS bought Duratek which was a publically held business doing power plant water cleanup and had a line of excellent resin for water cleanup. This became GTS Duratek, a publicly held company, and was soon separated from General Physics.
GTS Duratek bought SEG from Westinghouse.
GTS Duratek took over running of Barnwell for the State of South Carolina
The HP staff augmentation group of GTS Duratek was shut down when they lost the Duke Power contract. Soon after the QA group dissolved.
Energy Solutions bought GTS Duratek.
No idea about how the 1-800-number got to Bartlett, but it may have been through the buy out of NSS etc.
Now this is more the way I remember things

. Of course, one of my favorite memories of the days when Rad was running under many different banners, was the nicknaming of HPTS as Happy People Techs and Services.
