WASHINGTON, D. C. 20565 e
+m..... ok SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION SUPPORTING AMENDMENT NO.17 TO FACILITY OPERATING LICENSE NO. DPR-54 SACRAMENTO MUNICIPAL UTILITY DISTRICT RANCHO SECO NUCLEAR GENERATING STATION DOCKET NO. 50-312 Introduction Regulatory Guide 1.16, " Reporting of Operating Information A p r:e n d i r A Technical Specificatione', is the basis for reporting requirements four.d in Technical Specifications today.
When these Technical Specifications were issued, we requested that licensees use the formats in the guide for the Licensee Event Report (LER) and Monthly Operating Report.
In some cases licensees' us; of these formats was required by a reference to Regulatory Guide 1.16 in the Technical Specifications. After two years of experience with the reporting requirements identified in this guide, we reviewed the scope of information licensees are required to submit in the LER, Annual Operating Re, port, Monthly Ooerating Report and Startup Repcet.
Based on our review of LER's we developed a modified format for the LER to make this document more useful for evaluation purposes.
By letters sent in July and August 1977, we informed licensees of the n(w LER format and requested that they use it.
For those licensees who reference Regulatory Guide 1.16 in their Technical Specifications, we also requested that they propose a change which would replace this reference with appropriate words from the guide and which would delete mandatory use of the reporting forms contained in the guide.
From our review of all licensee reports, we determined that much of the information found in the Annual Operating Report either is addressed in the LER's or Monthly Operating Reports, which are submitted in a more timely manner, or could be included in these reports with Jr.ly a slight augmentation of the information already supelied.
Therefore, we ',oncluded that the Annual Operating Report could be deleted as a Technical Specification requirement if certain acd1tional information were provided in the Monthly Operating Reports.
As a result, we sent 010
[
k.
. letters during September 1977 to licensees informing them that a revised and improved format for Monthly Operating Reports was available and requested that they use it.
For those licensees with the Techt ical Specification reference to Regulatory Guide 1.16, the change deleting this reference, discussed above, would be necessary.
In addition, licensees were informed that if they agreed to use the revised format, they shculd submit a change request to delete the requirement for an Annual Operating Report except that occupational exposure data must still be submitted.
By letter dated November 10, 1977, the Sacramento Municipal Utility District (licensee) proposed an amendment to the Rancho Seco Nuclear Generating Station (facility) operating license.
This amendment would modify the Technical Specifications to permit use of LER and Monthly Operating Report formats different than those contained in Regulatory Guide 1.16 and delete the requirement for an Annual Operating Report.
Eva'uation The proposed change which would repl' ace the reference to RG 1.16 with appropriate wording from that guide is administrative in nature and does not cheige the operation of the reactor.
This charge provides wording in the Technical Specifications which identifies the required reports, states the circumstances under which they should be submitted and details the timing of such submittals.
The text does not specify in great detail the format and content of the reports as was previously done by reference to the guide.
The proposed change provides greater flexibility to accommodate changes to the reporting system and allows the licensee to use the recently revised LER and Monthly Operating Report formats and is therefore acceptable.
The licensee has also proposed to delete all but one of the four specified items in the Annual Operating Report.
The report which tabulates occupatior.al exposyre on an annual basis is needed and therefore, the requirement.to submit this information has been retained.
We have determined that the failed fuel examination informatidn does not need to be supplied routinely by licensees because this type of historical data can be obtained in a compiled form from fuel vendors when needed.
The information concerning forced reductions in power and outages will be supplied in the revised Monthly Operating Reports and the narrative summary of operating experience will be provided on a mo..hly basis in the Monthly Operating Report rather than annually.
The licensee
\\
. has committed to use the revised Monthly Operating Report format beginning with their report for January 1978 as requested. We nase concluded that all needed information will be provided and d-letion of the Arnual Operating Report is acceptable.
Environmental Consideration We have determined that this amendment does not authorize a charige in effluent types or total amourit s nor an inc rease in power lesel and will not result in any significant environmental impart.
Having made this determination, we have further concluded that th* anendment involves an action whic h is insignificant from the standpoint of ervironmental impact, and pursuant to 10 CFR 551.5(d)(4) that an environmental impact statement, or negetive declarattun ard environmental impact arreaital naed
- r. o t be prepared in conrection with tnt issuance of this amandment.
Conclusion We have concluded, ba s ett on the consider ations dise ussed above, that: (1) because the amendment does not involve a significant increase in the probability or consequences of accidents previously considered and does not involva a significant decrease in a safety margin, the amendment does not involve a significant hazards consideration, (2) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, and (3) such activities will be conducted in compliance with the Ccmmission's regulations and the issuance of this amendment will rot be inimical to the common defense and security or to the health ar'd safety of the public.
