UNITEDSTATES NUCLEAR REGULATORY COMMISSION WASHINGTON, O. C. 20555 SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION SUPPORTING AMENDMENT NO.
TO FACILITY OPERATING LICENSE NO. NPF-Pl WASHINGTON PUBLIC POWER SUPPLY SYSTEM WPPSS NUCLEAR PROJECT NO.
2 DOCKET NO. 50-397
1.0 INTRODUCTION
By letter da'ted August 12, 1985, the Washinoton Public Power Supply System requested revisions to the WNP-2 Technical Specifications, Sections 3/4.3.7.12 (Radioactive Gaseous Effluents Monitoring Instrumentation}
and 3/4.11.2.7 (Radioactive Effluents, Main Condenser).
The revisions are intended to clarify the operating condition for which radioactive effluent monitorina is required.
2.0 EVALUATION The staff review of the WNP-2 Technical Specifications relates specifically to changes that:
(1I specify that the offgas system*'radiation monitors.need to,function only during operation of the offgas system (and not'uring shutdown/refueling modes);
and (2) allow one of the two post treatment offgas radiation monitors to function as a backup pretreatment radiation monitor.
The staff finds the Technical Specification changes acceptable because they can only apply and should apply when noncondensable gas is flowing through the offgas system.
The changes will provide the licensee with additional operational flexibilitythat does not reduce the safety functions of the system.
- 3. 0 ENVIRONMENTAL CONSIDERATION This amendment involves a change in the installation and use of a facility component located within the restricted area as defined in 10 CFR Part 20 and changes in surveillance requirements.
The staff has determined that this amendment involves no significant increase in the amounts, and no significant change in the types, of any effluents that may be released offsite, and that there is no significant increase in individual or cumula-tive occupational radiation exposure.
The Commission has previously issued a proposed finding that this amendment involves no significant hazards consideration and there has been no public comment on such finding.
Accord-ingly, this amendment meets the eligibility criteria for categorical 8b11 1801 OSOOO397 Bb11Qb pDR

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.
4.0 CONCLUSION
The Commission made a proposed determination that the amendment involves no significant hazards consideration which was published in the Federal Register,(50 FR 41257) on October 9, 1985, and consulted with the state of Washington.
No public comments were received, and the state of Washington did not have any comments.
We have concluded, based on the considerations discussed above, that:
(1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed
- manner, and (2) such activities will be conducted in compliance with the Comnission s regula-tions and the issuance of this amendment will not be inimical to the common defense and security or to the health and safety of the public.
