Butler, Director BWR Project Directorate No. 4 Division of BWR Licensing U.S. Nuclear Regulatory Commission Washington, D.C. 20555 Perry Nuclear Power Plant Docket No. 50-440 Amendment I to NPF-58

Dear Dr. Butler:

Pursuant to 10 CFR 50.59, the Cleveland Electric Illuminating Company hereby requests amendment of Appendix A to the Perry Nuclear Power Plant operating license (NPF-58).

This letter provides seven (7) changes which CEI proposes be incorporated into the current Technical Specifications for Perry Unit 1. These seven changes consist of technical, editorial, and administrative changes. Each item is addressed individually in separate attachments, and each change has been determined to involve no significant hazards considerations.

Pursuant to 10 CFR 170.12, we have attached an application fee of $150.00.

We request that this amendment be processed by January 30, 1987. Should you have any questions, please feel free to call me.

Very truly yours, Gk Murray R. Edelman Senior Vice President Nuclear Group MRE:nje Attachments cc: Jay Silberg, Esq.

' Attachment 1 PY-CEI/NRR-0549 L Summary

. Technical-Specification 3.6.2.6, Drywell Average Air Temperature, limits the maximum average drywell air temperature. The surveillance is performed by -

taking the arithmetical average of the' temperatures at the locations specified

. by Surveillance Requirement 4.6.2.6. _The Perry Technical Specifications-

~

- presently list. six (6) instruments. which are to be used for determining the drywell average air. temperature. CEI proposes to increase the number of instruments used to perform this surveillance f ron six (6) to seventeen (17).

y During the development of the Perry Technical Specifications, only the safety related, Class 1E instruments required by Reg. Guide 1.97 were included in this

- Surveillance Requirement.;_Since this specification ensures the drywell average

temperature is consistent with the safety analysis (pre-accident conditions),

- all available temperature instruments should be used in the determination of the average. . This change request would list the locations of all instruments presently available to measure air temperature in the drywell.

l~.. -.

Justification and Significant Hazards Analysis The standards used tu arrive at a determination that a request for amendment requires no signific.Mt hazards consideration are included in the Commission's regulations, 10 CFR 50.92, which state that the operation of the facility in accordance.with the proposed amendment would not (1)-involve a significant

, increase in the probability or consequences of an accident previously i ' evaluated, (2) create the possibility of a new or different kind of accident from any accident previously evaluated, or (3) involve a significant reduction

! in-a margin of safety.

4

CEI has reviewed the proposed change with respect to these three factors.

l The limitation on drywell average air temperature as stated in the Technical Specification Bases, is to ensure the peak drywell temperature does not exceed the design temperature of 330 F during LOCA conditions. This change request  ;

will not alter the basis for which the requirement exists, but will simply increase the number of instruments available in performing the surveillance, thereby providing a more representative average air temperature.

Because the basic surveillance requirement has not changed, and because the surveillance will still be conducted in the same manner and at the same frequency, we have concluded that the change will neither increase the probability or consequences of a previously evaluated accident nor create

. the possibility of .1 new or dif ferent kind of accident. In addition, a more t i representative average air temperature better meets the intent of this specification, as described by its Bases Section. Thus, this change will not result in a decrease in any margin of safety.

For these reasons, CEI has concluded that this proposed change involves no

' significant hazards conditions.
