SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION SUPPORTING AMENDMENT NO. 86 TO FACILITY OPERATING LICENSE NO. DPR-59 POWEP, AUTHORITY OF THE STATE OF NEW YORK JAMES A. FITZPATRICK MUCLEAR POWER PLANT DOCKET NO. 50-333 1.0 Introduction By letter dated October 9, 1984, the Power Authority of the State of New York (the licensee) proposed certain changes to the Technical Specifications (TS) to cor. rect a typographical error found in Table 3.2 7 of Appendix A.
As the existing table is written, instruments used to detect high reactor pressure for the purpose of initiating a recirculation pump trip are required to have a setpoint " greater than or equal to 1120 osia" rather than a setpo, int "less than or equal to 1120 psig." This incorrectly establishes a lower limit instead of an upper limit for'this setpoint.
2.0 Evaluation The intent of a recirculation pump trip is to provide a means of reducing reactor power in the event of a failure-to-scram. Table 3.2-7 should correctly establish an upper limit for the reactor pressure trip setpoint; exceeding this setpoint should trip the recirculation pumps, thereby reducing reactor power and, consequently, reactor pressure.
In the Final Safety Analysis Report, Appendix E, Section E.32, the licensee, with reference to General Electric topical report NED0-10349,
" Analysis of Anticipated Transients Without Scram," committed to making design changes which would provide for tripping the recirculation pumps on a high reactor pressure event. The NED0-10349 report concluded that tripping the recirculation pumps when reactor pressure was preater than or equal to 1150 psig was effective in keeping reactor power, pressures, and temperatures below safety limits and for allowing time for appropriate operator action. The licensee had historically used a setpoint valua of 1135 psig until discovery of the error in August 19P4 Shortly after.
discovery, the setpoint was readjusted to a value below 1120 psig.
Although the licensee failed to recognize the error in the TS until Aucust 19P4 we find that no significant safety hazard existed prior to its discovery and subsequent readjustment of the setpoint because plant procedures assured that at no time was the 1150 psig setpoint upper limit referenced in NED0-10349 exceeded.

We conclude that the licensee's proposed amendment provides a necessary
~
correction. to the TS and is,.therefore, 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 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 issued a proposed finding that this amendment involves no significant hazards consideration and there has been no public comment 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 connec' tion 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 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 be inimical to the common defense and security or to the health and safety of the public.
