REFERENCE:

(a) Letter from Mr. G. C. Creel (BG&E) to Document Control Desk (NRC), dated April 30, 1991, Request for License Amendment; One-time Schedular Extension of a Periodic Report Gentlemen:

Technical Specification 6.9.1.8 requires that a semiannual radioactive effluent release report be sent within 60 days after January 1 and July 1 of each year, except for the Strontium 89 and Strontium 90 analysis results, which are due within 120 days of January 1 and July 1 of each year. On April 25, 1991, we identified the fact that the first strontium report for 1991, due by April 30,1991, would not be submitted on time due to a delay in transporting the samples to the offsite lah for analysis. We anticipate recciving the results of this analysis in time to submit the report by June 29,1991.

Because this invohes a Technical Specification requi:cment, we submitted a request for license amendment l Reference (a)] to extend the due date on a one-time basis. Our basis for this request considered the fact that in this case, the lateness of the report is not safety significant. Ilowever, we

, understand that our request for schedular extension was not made sufficiently in advance of the subject report's duc date to allow NRC consideration of the request in a timely fashion.

Consequently, we hereby withdraw our license amendment request.

As noted in out April 30, 1991 letter, the cause of the delay in shipping the sampics is being investigated. When the investigation is complete, we will take approptiate actions to prevent recurrence and document the resolution of the problem.

l- The semiannual radioactive effluent release report covers liquid and gaseous efnuents, which include i

fission product isotopes, among which are Strontium 89 and 90. The samples measured give an after-i the-fact confirmation that the reicases that occurred during the time period covered were within limits. Technical Specification 6.9.l.8 allows an additional 60 days to submit a supplemental report 3

, hiay 23,1991 Page 2 containing the Strontium 89 and 90 analyses re:,ults because these analyses take more time to complete than the other analyses and are best performed offsite.

Ilistorical results for Strontium 89 and 90 have been very low, with airborne results often less than the minimum detectable activity. The power history for both units during the time frame covered was

)

low, as were the results for th: other isotopes. Therefore, the strontium results for the period in question are expected to be low.

1 Based on the above, we have concluded that the delay in submitting the strontium analysis results for  ;

the l'ust half of 1991 will not have an adverse effect on safety. Similarly, our withdrawal of the amendment request in Reference (a) will have no negative impact on safety.

Should you have any further questions regarding this matter, we will be pleased to discuss them with you.

Very truly yours, m
