C. 20555 Perry Nuclear Power Plant Docke t No. 50-440 Technical Specification Change Request Ge ntleme n :

The Cleveland Electric Illuminating Company (CEI) hereby requests Amendment of Facility Operating License NPF-58 f or the Perry Nuclear Power Plant, Unit 1.

In accordance with the requirements of '10 CFR 170.12 a check in the amount of

$150.00 will follow under separate letter. In accordance with requirements of 10 CFR 50.91(b)(1), a copy of this request for amendment has been sent to the State of Ohio as indicated below.

This amendment requests revision of Technical Specification Section 3.3.2 Table 3.3.2-2. Numerous Trip Setpoints and Allowable Values are footnoted with a statemnt that these were initial values, and that the final values would be determined during the startup test program. The footnote also states that any required setpoint change would be submitted to the Commission within 90 days of s tartup te st comple tion. The purpose of this revision is to provide the final values for the RHR/RCIC Steam Line Flow-liigh Trip Setpoint and Allowable Value based on the results of the startup testing program, and to delete the f ootnote f rom all Trip Setpoints and Allowable Values since the s tartup test program has been completed. A copy of the proposed Technical Specification pages is enclosed.

Should you have any questions, please feel f ree to call me.

• PT-CEI/NRR-0765 L Page 1 of 3 Summary This proposed amendment to the Perry Nuclear Power Plant Technical Specifications requests a change to one Isolation Actuation Instrumentation Trip Setpoint and Allovable Value based on startup test results, and deletes a footnote throughout the Isolation Actuatien Instrumentation Setpoint Table (Table 3.3.2-2) referring to setpoint adjustments found during the Startup Test Program. Only one Setpoint/ Allowable Value (RHR/RCIC Steam Line Flow-High) needs adjustment based on startup test results. The deletion of the footnote is purely an administrative change resulting from the completion of the Startup Test Program, thereby making the footnote not applicable.

Safety Analysis Technical Specification Table 3.3.2-2 was written recognizing that several of the Trip Setpoint and Allovable Values were best approximations based on the design of the plant, but vould need to be verified as part of the startup test program. Where values needed to be verified, a footnote was added to the table indicating this was an initial setpoint, and any changes vould be submitted to the NRC within 90 days of completion of the startup testing.

Eleven (11) different isolation actuation instrumentation trip functions contained this footnote. Ten of these were verified to be acceptable during startup testing, and consequently no changes need to be made. One trip function, RHR/RCIC Steam Line Flow-High Trip Setpoint and Allovable Value, was determined to require revised setpoint values. The existing and new Trip Setpoints and Allovable Values are the following:

Existing Value Proposed Value Trip Setpoint f 105" H 2O f 52.1" H 2O l Allovable Value f 114" H 2O f 53.6" H 2O The purpose of this trip function is to isolate the combined RHR/RCIC steamline, if a high steam flov (indicative of steamline break) condition exists in this line. These new values are more conservative than the existing values, and the Startup Test Program has shovn that the proposed setpoints vill conservatively indicate an abnormal high steam flow condition without causing inadvertent trips during normal steam flow conditions. Therefore, the change poses no safety concern.

This change also proposes to delete the footnote from all eleven (11) isolation actuation instrument trip functions, since this footnote is no longer applicable. This is purely an administrative change and poses no safety concern.

- PY-CEI/NRR-0765 L Page 2 of 3 Significant Hazards Analysis The standards used to arrive at a determination tnat a request for amendment requires no significant 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 vould not (1) involve a significant increase in the probability or consequences of an accident previously 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. CRI has reviewed the proposed change with respect to these three factors.

This proposed change does not involve a significant increase in the probability or consequences of an accident previously evaluated.  ;

The accident basis for establishing the Trip Setpoint and Allovable Value has not changed (125% total maximum RCIC and RHR Steam Condensing Steam Flov).

The Trip Set Point and Allovable Values are being changed based on Startup Test Program results of normal RCIC and RHR steam condensing steam flow rather than being based solely on calculations. As such there is no change to the probability of previously evaluated accidents. Furthermore the consequences of an accident would not change. Thus, there is no increr.se in the probability or consequences of any accident previously evaluated. Deletion of the footnote is strictly administrative in nature and can not increase the probability or consequences of an accident.

The proposed change does not create the possibility of a new or different kind of accident from any accident previously evaluated.

The revision to the RHR/RCIC Steam Flov-High Trip Setpoint and Allovable Value, also does not create a new or different kind of accident from any previously evaluated. The purpose of this instrumentation is to isolate the RHR/RCIC steamline in the case of a steamline break. The proposed change lovers the trip setpoint. This proposed trip setpoint has been established to prevent normal system steam flov from causing a system isolation. Therefore, no new or different accident has been created. As stated above the deletion of the footnote is administrative in nature and cannot create the possibility of a new or different kind of accident.

The proposed change does not involve a significant reduction in the margin of safety.

As discussed above the Trip Setpoint and Allovable Value are being adjusted based on the results of steam flow measurements taken during the Startup Test Program. The bases for the setpoints have not changed. Thus the change does not involve a significant reduction to the margin of safety. Deletion of the footnote is administrative and does not affect the margin of safety.

'3 PY-CEI/NRR-0765 L Page 3 of 3 Environmental Impact

-The Cleveland Electric Illuminating Company has revieved the proposed Technical Specification change against the criteria of 10 CFR 51.22 for the environmental considerations. As shown above, the proposed change does not involve a significant hazards consideration, nor increase the types and 1 amounts of effluents that may be released offsite, nor significantly increase I individual or cumulative occupational radjation exposures. Based on the foregoing, CEI concludes that the proposed Technical Specification change, meets the criteria given in 10 CFR 51.22(c)(9) for a categorical exclusion from the requirement for an Environmental Impact Statement.
