Denton, Director Of fice of Nuclear Reactor Regulation U.S. Nuclear Regulatory Commission Washington, D.C. 20555 Perry Nuclear Power Plant Docket No. 50-440 Additional Change to Technical Specifications for Full Power Licensing

Dear Mr. Denton:

This letter supplements our letters dated June 18, 1986 and July 18, 1986 and provides one additional change that the Cleveland Electric illuminating Company requests be included in the Technical Specifications which will accompany the full power operating license for the Perry Nuclear Power Plant -

Unit 1. This item represents enhancements to the Technical Specifications.

The justification and the proposed markup pages are attached.

This change does not affect CEl's ability to safely operate the Perry Nuclear Power Plant-Unit I under its current license. Thus, no amendment of the present low power license is being requested. If you have any questions, please call me.

Very truly yours '

Justification Technical Specification 3.8.4.2 Reactor Protection System Electric Power Monitoring Technical Specification 3.8.4.2 is presently applicable at all times. This change request would change the applicability of Specification 3.8.4.2 to Operational Conditions 1, 2, 3, 4 , and 5.

The RPS Electric Power Monitoring Assemblies maintain the voltage and frequency of the output of the RPS MG sets to acceptable values. If the voltage and f requency of the power to the RPS and the containment isolation instruments is

! maintained within the limits of Surveillance Requirement 4.8.4.2, the assumptions used in the setpoint calculation will remain valid. Thus, confidence in the RPS instrumentation and the isolation actuation instrumentation to actuate at their respective setpoints is assured.

The RPS instrumentation and the isolation actuation instrumentation is only required during specified operational conditions, not at all times. The purpose of the RPS is to:

a. Preserve the integrity of the fuel cladding.

f

b. Preserve the integrity of the reactor coolant system.
c. Minimize the energy which must be adsorbed following a loss-of-coolant accident, and
d. Prevent inadvertant criticality.

4 The purpose of the isolation actuation instrumentation is to mitigate the consequences of accidents by prescribing trip setpoints and response times for the isolation of the reactor systems.

1 Changing the applicability of Specification 3.8.4.2 will not reduce the effectiveness of either the RFS instrumentation or the isolation actuation instrumentation. This change will only make the applicability of the power supply for this instrumentation consistent with the applicability for the instrumentation itself.
