Dear Mr. Michaels:
This is to confirm the informatica on the NTR graphite I gave you during our telephone conversation of June 24, 1987. The graphite moderator / reflector was dismantled in 1976. The graphite interior to the core can was discarded and replaced. The exterior graphite was annealed to 300 C.
The graphite has l
received an exposure of approximately 43.3 mwd since the annealing.
Sincerely, h, $, D G. E. Cunningham Senior Licensing Engineer (415) 862-4330
