~1.0 1NTRODUCTION t
By letter dated February 6, 1989, as supplemented on October 25, 1989, Portlana General Electric Company (PGE) submitted proposed change (LCA-172) to the Trojan Technical Specifications (TTS). The proposed change would revise the surveillance requirements for containment leek
~ testing to make TTS 4.0.2 not applicable. The October 25, 1989 submittel submittal provided clarifying information which did not alter the action noticea or effect the staff 5 initial' determination published in the Federe,1, [egister on November 17, 1989, 2.0 FVALUATION TTS 3/4.6.1.2 requires that an " Integrated Leak Rote Test (ILRT)" be i
performed at 40110-month intervals. TTS 4.0.2 requires that each survetilante be performed with a total maximum time interval for any
+
three consecutive surveillance intervals not to exceed 3.25 times the surveillance interval. As discussed below, these two TTS can conflict L
with each other.
l-Three ILRT's could be performed at 49 month intervals, each which would clearly. satisfy the 40 10 month interval of TTS 3/4.6.1.2.
- However, this would not satisfy the TTS 4.0.2 requirement of performing three surveillances within 3.25 times the interval (40 months x 3.25 = 130 N
months allowed, whereas 49 months actual x 3 = 147 months). To resolve l
this conflict, TTS 3/4.6.1.2 is being revised to make TTS 4.0.2 not I
applicable.
The change tv TTS 3/4.6.1.2 will not affect test frequency, test methods, or acceptance criteria; therefore, the current procedure will not be changed. This change is also consistent with the Westinghouse Standard Technical Specifications.

- Since there will be no change to current procedure for " Integrated Leak Rate Testing", and the change provides consistency in the Technical i
l Specifications, the staff finds the proposed change to TTS 3/4.6.1.2 to.be acceptable.
h 3.0 CONTACT.WITH STATE OFFICIAL i
The NRC staff has notified the Oregon Department of Energy of the proposed issuance of this anendment along with the proposed determination of no significant hazards considetation. No comnents were received.
4.0 ENVIRONMENTAL. CONSIDERATION L
This amendment involves a change in a surveillance requirement. The st6ff has determined that the 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 cumulative occupational radiation exposure. The Commission has previously published a proposed finding-that the amendment involves no significant hazards consideration and there has been no public comment on such finding.
Accordingly, the anendnent 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 inpact statement or environnental assessment need be prepared in connection with the issuance of the amendment.
5.0 CONCLUSION
l We have concluded, based on the considerations discussed above, that (1) there r
is reasonable assur;nce th6t the health and safet of the public will not be endangered by operation in the proposed manner, (y) such activities will be 2
conducted in compliance with the Consnission's regulations, erd (3) the issuance of the amendment will not be inimical to the common defense and security or to the health and safety of the public.
