Dear Mr. Eisenhut:
Re:
Turkey Point Unit 4 Docket No. 50-251 Steam Generator Ins ections The results of the Turkey Point Unit 4 steam generator inspections conducted during the current outage are attached.
The inspections which were performed in accordance with Turkey Point Unit 4 operating license DPR-41 showed no new phenomena and verified that the general pattern of denting in Unit 4 is within predictable limits and consistent with previous inspections of the Turkey Point Units.
The general criteria applied for steam generator inspections and preventive plugging are the same as previously applied to Turkey Point Units 3 and 4.
This approach provides reasonable assurance of steam generator tube integrity such that safe operation of the unit during normal full power operation and during hypothetical accident conditions is assured for an operating period in excess of six equivalent full power months.
Therefore, the implementation of thi s program with the resulting preventive plugging, enables continued safe full power operation of Turkey Point Unit 4.
Total steam generator tube plugging at the conclusion of the current outage will be approximately 23.8X.
This is conservatively bounded by the 25K tube plugging ECCS analysis.
The results of this inspection and the preventive tube plugging program have been reviewed by the Turkey Point Plant Nuclear Safety Committee and the Florida Power 8 Light Company Nuclear Review Board.
They have concluded that based on the inspection results, the implemented plugging pattern, and previously submitted
- analyses, that the return of Turkey Point Unit 4 to full power operation for at least six equivalent months does not involve an unreviewed safety question.
In accordance with condition D.l of operating license DPR-41, Florida Power 8
Light Company requests permission to return Unit 4 to power operation for a period of six equivalent full power months.

Based on our current schedule, we could be ready to resume power operation by January 11, 1981.
l<e will keep you advised of any significant changes.
Me have determined that this is a Class III request in accordance with 10 CfR 170.
Accordingly, a check for $4,000 is enclosed.
