20555 NRC 00CKETS 50-321, 50-366 OPERATING LICENSES DPR-57, NPF-5 EDWIN I. HATCH NUCLEAR PLANT UNITS 1, 2 STATUS OF CONTAINMENT PURGE AND VENT Gentlemen:
On October 1,
1982, we responded to your rennest for additional information on the status of containment purge and vent.
On November 5, 1982 in a telephone conversation between Mr. M. Fairtile of your staff and Mr. R. D. Baker of this staff, it became apparent that the above-referenced letter was never received by NRC.
Because the original copy of the letter was apparently lost, the attached copy is provided in lieu of an original.
If you have any further questions, please contact this office.
Very truly.yours, fN &
