SAFETY EVALL't.TIOh B) THE OFFICE OF NUCLEAR REACTOR REGULATION SUPPORTING AMENDMENT NO. 7 TO OPERATING LICENSE NO. NPF-42 KANSAS GAS & ELECTRIC COMPANY LANSAS CITY POWER AND LIGHT COMPANY KANSAS ELECTRIC POWER COOPERATIVE, INC.
WOLF CREEK GENLrgINGSTATION DOCKET NO. 50-482 INTRODUCTION By letter dated May 31, 1985, Kansas Gas and Electric Company (the licensee) requested various changes to the Technical Specifications for the Wolf Creek Generating Station. The staff's evaluation of the charges is as-follows:
EVALUATION CHANGE 1 - Change the entries for the Total Allowance and Sensor Error for Functional Unit 7, Overtemperature AT, in Table 2.2-1 from "7.6" and "1.73 + 0.67" to "7.2" and "1.55 + 0.9" respectively.
CHANGE 2 - Change the entry for Sensor Error for Functional Unit 8, Overpower AT, in Table 2.2-1 from "0.16" to "0.15".
CHANGE 3 - Change the entries from Z and Sensor Error for Functional-Unit 12, Reactor Coolant Flow-low, in Table 2.2-1 f rom "2.27" and "0.6" to "2.19" and "0.8" respectively.
CHANGE 4 - Change the allowable value (for Overterrperature AT) in Note 2 to Table 2.2-1 from "3.3%" to "2.9%."
l CHANGE 5 - Change the allowable value-(for Overpower aT) in hote 4 to Table 2.2-1 from "4.1%" to "4.0%."
The above changes for Overtemperature AT, Overpower AT, and Reactor Coolant l
Flow-Low reactor trip instrurent channels are being requested to encompass larger RdF RTD calibration errors than cri Since the revised values are based on actual (not estimated)ginally estimated.

O ENVIRONMENTAL CONSIDERATION The atenonent involves a change in use of facility components located within the restricted area as defined in 10 CFR Part 20 and changes in surveillance requirements.
The staff has deternined that the amendment involves no significant increase in the amounts, and no significant change in the types, of any effluents that nay be released offsite and that there is no sifnificant increase in irdividual or cumulative occupational exposures. The Commission has previously
. issued a proposed finding that the acendment involves no significant te7ards consideration, and there have been no public comments on such finding. Accordingly, the amendnent neets the eligibility criteria fcr cetecorical exclusion set forth in 10 CFR Section 51.22(c)f91 Pursuant to 10 CFR 51.22(b) no environn. ental impact statement or environrental assessment need be prepared in connection with the issuance of this amendment.
CONCLUSION The Commission made a proposed determination that the amendment involves no significant hazards consideration which was published in the Federal Register (51 FR 3d169) on September 25, 1986 and consulted with the state of Kansas.
No public comments were received, and the state of Kansas did not have cry 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 twill 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.
