SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION SUPPORTING AMENDMENT N0.73 TO FACILITY OPERATING LICENSE NO. DPR-54 SACRAMENTO MUNICIPAL UTILITY DISTRICT RANCHO SECO NUCLEAR GENERATING STATION 4
DOCKET NO. 50-31' INTRODUCTION l
By application dated September 20, 1984, Sacramento Municipal Utility l
District (the licensee) requested changes to Facility Operating License No.
DPR-54 for Rancho Seco Nuclear Generating Station (the facility). The proposed changes would revise the facility Technical Specifications to (1) change the name of the Reactor Building Stack, Auxiliary Building Stack,
~
Reactor Building Service Area Vent and the Radwaste Service Area Vent Particulate Monitors to Particulate Samplers, (2) change the name of the Radwaste Service Area Iodine monitor to Iodine Sampler, and (3) delete the source check, instrument channel calibration and the channel check for these instruments.
DISCUSSION AND EVALUATION This amendment corrects an error in the Technical Specifications which states that the above listed monitoring instruments have sources or channels which can be calibrated. Since they have no such elements, source checks, channel calibration and channel check requirements are not applicable, and these functions should be deleted from the Technical Specifications.
The name changes requested by the amendment are appropriate since the name
" sampler" more correctly describes the function and surveillance requirements for these instruments employed to assay radioactive particles and iodine in various ventilation exhaust streams. These instruments do not continuously monitor the stream but collect a sample on filter paper and charcoal filter cartridges. After a specific quantity of air has been passed through the samplers, the cartridges are removed and counted.
These changes are consistent with the standard Radiological Effluent Technical Specifications (RETS) for Pressurized Water Reactors.
ENVIRONMENTAL CONSIDERATION This amendment changes a surveillance requirement. We have determined that the amendment involves no significant increase in the amounts, and no j
significant change in the types, of any effluents that may be released i
offsite, and that there is no significant increase in individual or cumulative occupational radiation exposure. The Comission has previously issued a I
proposed finding that this amendment involves no significant hazards consideration and there has been no public coment on such finding.

. Accordingly, this amendment meets the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9).
Pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the issuance of this amendment.
Conclusion We have concluded, based on the considerations discussed above, that:
(1) there is reasonable assurance that the health and safety of the will not be endangered by operation in the proposed manner, and (2) public such activities will be conducted in compliance with the Commission's regulations and the issuance of this amendment will not ce inimical to the common defense and security or to the health and safety of the public.
