4 UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D. C. 20555 SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION SUPPORTING AMENDMENT NO. 91 TO FACILITY OPERATING LICENSE NO. DPR-59 POWER AUTHORITY OF THE STATE OF NEW YORK JAMES A. FITZPATRICK NUCLEAR POWER PLANT I
DOCKET N0. 50-333 j
1.0 Introduction By letter dated January 30, 1985, the Power Authority of the State of New York (PASNY), licensee for the James A. FitzPatrick Nuclear Power Plant, submitted proposed changes to the Technical Specifications (TSI to

correct an error in Table 3.7-1, " Process Pipeline Penetrating Primary Containment," that was inadvertently introduced at the initial issuance of the TS. The proposed amendment changes isolation signals for two reactor water sample system (RWS) valves (drywell penetration X-41) from "B, C, D, E & P" to "B & C" to reflect the original design basis of the plant.
2.0 Evaluation f
The isolation valves for the process lines communicating directly with the reactor vessel form isolation valve group A.
Each of these lines has two isolation valves in series, one inside and one outside the primary containment. The two RWS isolation valves located on a 3/4" sample line are among this group.
Isolation s.ignals B, C, D, E and P are part of an isolation function that effects closure of various group A isolation valves.
For certain trip conditions, only certain isolation functions are initiated. Group A isolation functions include generation of isolation signals for the following components:
1.
Main steam line isolation valves 2.
Main steam line drain isolation valves 3.
RWS isolation valves 4.
Condenser vacuum pump The condenser vacuum pump is tripped only for a main steam line high radiation trip. RWS isolation valves are designed to receive an is.olation i
signal only for the following two signals:
"B"
" Reactor vessel low low water level" l
"C"
" Main steam line high radiation" i

The remaining group A valves are designed to isolate on any of the following signals:
"B"
" Reactor vessel low low water level" "C"
" Main steam line high radiation'*
"0"
" Steam line high flow" "E"
" Steam tunnel high temperature" "P"
" Main steam line low pressure" Based on a review of the above information, the staff finds that the inclusion of signals D, E and P in Table 3.7-1 for drywell penetration X al does not reflect the actual design basis of the plant and represents an error.
The staf.f concludes that the proposed TS revision corrects an error to make the TS conform to the design basis of the plant and is, therefore, g
_ -acceptable.
3.0 Environmental Consideration This amendment involves a change in the installation or use of a facility component located within the restricted area as defined in 10 CFR Part 20.
The staff has determined that the amendment involves no significant increase in the e ounts, 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 Comission has previously issued a 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 elioibility criteria forcategoricalexclusionsetforthin10CFR51.??fc)(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 Conclusions 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 Consnission's regulations 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.
