Dear Mr. Eisenhut:
Re:
Turkey Point Unit 3 Docket No. 50-250 Steam Generator Ins ection On January 11, 1980 (L-80-10), Florida Power 5 Light Company submitted the results of the recent Turkey Point steam generator inspection and preventive tube plugging.
This letter supplements the information submitted in that report.
As discussed with Messrs.
Grotenhuis, Liau, and Murphy of your Staff, two tubes were inadvertently omitted from the recent inspection program -- tube R 22 C 13 in 3A steam generator, and tube R 12 C 80 in 3B steam generator.
These tubes, which are in areas that have not exhibited generalized denting to date, should have been inspected because they failed to pass an 0.650" probe during the previous inspection.
The tubes surrounding the R 22 C
13 tube in 3A steam generator all were inspected and all passed a 0.650" probe.
The R 12 C 80 tube in 3A steam generator and surrounding tubes were mistakenly inspected also with acceptable results (in lieu of the R 12 C 80 tube in 3B steam generator as required).
By the time that this oversight had been determined, the steam generators had been closed up and the inspection and plugging equipment had been removed from the site.
Florida Power 5 Light Company along with its NSSS vendor evaluated these omissions.
We concluded, based on the locations of the tubes and the inspection results from tubes in the general vicinity of the omitted tubes, that these restricted tubes were isolated occurrences and not part of an area experiencing general
- denting, and that the probability of these tubes develop-ing a leak in the anticipated operating period prior to the next steam generator inspection was remote.
We also concluded that existing license conditions regarding steam generator operations assure the protection of the health and safety of the public in the unlikely event that a tube leak should develop.
Based on the foregoing, and the additional 10-15 man-rem required to open the steam generators and inspect the omitted tubes, along with schedular ao i 800122p ~~

SERVING PEOPLE
Office of Nuc1 ear Reactor Regul ati on Page'wo considerations, we concluded that inspection of the omitted tubes is not warranted at this time.
These tubes will be inspected during the next scheduled inspection.
We understand that your Staff concurs with our evaluation.
Please feel free to contact me if you should have any question in this matter.
Very trul
- yours, Robert E. Uhrig Vice President Advanced Systems 8 Technology REU/GDW/ah cc:
