Not sure about Georgia - must be a fairly common problem though as I found a
case at Browns Ferry Alabama (1975) where it all went tits up - no radiation
danger on that one, but they had to manually scram as all the automated
systems were lost - including the emergency cooling system that they had to
jury-rig. Can't find a record of the one I remember on the web anyplace - I
can find an unrelated note that TMI operators had to go adjust valves and
take readings in a "hot" environment, but their exposure badges only showed
1 REM at worst (with a note that this was approximately three weeks maximum
allowable intake). Fairly sure it wasn't american though :(
My references were on paper, not the web, and I *should* still have them. I
will look about and if I can find them, scan them in for you to take a look
at :)
