Docket No.: 50-321 4 SEP 1987 Mr. James P. O'Reilly Senior Vice President - Nuclear Operations i Georgia Power Company I P.O. Box 4545 Atlanta, Georgia 30302

Subject:

IGSCC Inspections - Hatch Unit 1 1987 Maintenance / Refueling Outage (TAC 64777)

By letter dated July 1,1987, you were informed that the staff had reviewed the information provided by GPC regarding the intergranular stress corrosion ,i cracking (IGSCC) inspections and repairs performed on the Hatch Unit I reactor coolant piping systems during the 1987 maintenance / refueling outage., Based upon that review, the staff had concluded that Hatch Unit 1 can be safely operated for the next 18-month fuel cycle. However, the Safety Evaluation which provided the basis for that conclusion had not been completed. This letter transmits that Safety Evaluation and confirms our earlier conclusion that Unit 1 may be safely operated for the remainder of the current 18-month fuel cycle.

Because of the uncertainties about the long term behavior of the piping, we require that the plan for inspection and/or modification to the recirculation and other austenitic stainless steel piping systems operating over 200 F during the next operating cycle be submitted for our review and comment at least three months before the start of the next outage.

Please contact me if you have any questions regarding this matter.

Sincerely, W\

lawrence P. Crocker, Project Manager Project Directorate 11-3 Division of Reactor Projects I/II
