20555 Re: Operating License DPR-54 Docket No. 50-312 Annual Operating Report 1975
Dear Sir:
Please find enclosed forty (40) copies of Change No.1 to the Rancho Seco Nuclear Station Annual Operating Report for the period ending December 31, 1975.
Submittal of this change fulfills the request made by the Region V Regulatory Office concerning the submittal of corrected data.
This change corrects values in Section II, Page 2-49, reported for the fourth quarter radiological analysis of algae.
These data were j
found to be in error during an Internal Quality Assurance Audit subse-j quent to the submission of the Annual Report.
The second quarter data on algae was incorrectly repeated as the fourth quarter results.
The new algae data provides completely new values for all isotopes and adds a value for CoS8, Please insert these changes in the copies of the Annual Report previously forwarded to you to bring the report up to date.
Respectfully,
. '. h)LL J. J. Mattimoe Assistant General Manager and Chief Enginee:
