SUMMARY

OF MEETING HELD ON FEBRUARY 25, 1981 WITH INDIANA AND MICHIGAN ELECTRIC COMPANY AND AMERICAN ELECTRIC POWER SUPPLY COMPANY TO DISCUSS THE POWER DISTRIBUTION LIMITS FOLLOWING RELOAD FOR DONALD C.

COOK, UNIT NO.

2 A meeting was held on February 25, 1981 with Indiana and Michigan Electric Company

( I8MEC), American El.ectric Power Supply Company (AEP) and Westinghouse Electric Company.

The purpose of the meeting was to provide AEP the oooor-tunity of discussing a peaking factor (Fq) Technical Specification change request they expect to submit in the near future.

The attendance list is enclosed (Enclosure 1).'he current Fq peaking factor Technical Specification for Unit ¹2 requires the continual usage of the Axial Power Distribution Monitoring System (APDMS).

In addition, the Unit ¹2 Technical Specifications for Fq are different from those in Unit ¹1.

Since Unit ¹2 is primarily a base loaded plant, IQ1EC intends to propose Technical Specification changes which will allow credit for the low Fg which exists when the plant is base loaded and reformating the Technical Spec-ifications.

In this way, the Unit ¹2 Tech Specs will be brought more in line with Unit ¹1 Tech Specs and the usage of the APDMS will be reduced.

The basic changes that the licensee proposes to make to the Technical Specifications are shown in Enclosure 2.

Enclosure 3 is a summary of the benefits expected to be derived from the Tech Spec change.

We made the following comments on the presentation:

1) the peaking factor report should be submitted 60 days prior to startup.

The report should include a statement on methodology and xenon function values, and 2) reference to previously submitted reports can be used to provide technical justification for the proposed change.

COOK, UNIT NO.

2 A meeting was held on February 25, 1981 with Indiana and Michigan Electric Company (IMEC), American El,ectric Power Supply Company (AEP) and Westinghouse Electric Company.

The purpose of the meeting was to provide AEP the oppor-tunity of discussing a peaking factor (Fq) Technical Specification change request they expect to submit in the near future.

The attendance list is enclosed (Enclosure 1).

The current Fq peaking factor Technical Specification for Unit 82 requires the continual usage of the Axial Power Distribution Monitoring System (APDMS).=

In addition, the Unit 82 Technical Specifications for Fq are different from those in Unit 81.

Since Unit 82 is primarily a base loaded plant, I8MEC intends to propose Technical'Specification changes which will allow credit for the low Fg which exists when the plant is base loaded and reformating the Technical Spec-ifications.

In this way, the Unit ~2 Tech Specs will be brought more in line with Unit 81 Tech Specs and the usage of the APDMS will be reduced.

The basic changes that the licensee proposes to make to the Technical Specifications are shown in Enclosure 2.

Enclosure 3 is a summary of the benefits expected to be derived from the Tech Spec change.

We made the following comments on the presentation:

~ECH SPEC CHANGES Enclosure 2

BASIC CHANGES TO THE COOK UNIT 2 TECH SPEC FOR OPERATOR CONVENIENCE THE PROPOSED TECH SPEC IS SIMILAR IN FORMAT TO UNIT 1 Fg(Z)

EXPECTED DURING PLANT OPERATION IS REDUCED BY RESTRICTING PLANT MANEUVERS IN BASE LOAD OPERATION, SURVEILLANCE TO VERIFY SAFE PLANT OPERATION BELOW THE Fg (Z) LIMITS IS ACCOMPLISHED BY PERIODICALLY MEASURING Fg(Z)

WITH A FULL CORE FLUX MAP TAKEN UNDER EQUILIBRIUM CONDITIONS, A M(Z) FUNCTION TO ACCOUNT FOR TRANSIENTS IS INTRODUCED TO INCREASE THE MEASURED FQ(Z)>>

THE PRODUCT OF THE MEASURED Fg(Z) MULTIPLIED BY THE 'N(Z)

FUNCTION IS THEN COMPARED, TO SAFETY LIMITS.

Fg(Z)

SURVEILLANCE REPLACES EXPLICIT FXY(Z) SURVEILLANCE WHILE RETAINING THE INTENT OF USING A MEASURED PARAMETER TO VERIFY TECH SPEC LIMITS CYCLE DEPENDENT FACTORS ARE REMOVED BY ADOPTING A PEAKING FACTOR REPORT>>

THE PROPOSED TECH SPEC PROVIDES A MORE CONVENIENT FORM OF MONITORING Fg TO ASSURE SAFETY LIMITS ARE NOT VIOLAiEDi FXY(Z) SURVEILLANCE IS IMPLICITLY INCLUDED IN THE EQUILIBRIUM MEASURED Fg(Z)

THE OPERATING Fg(Z)

VALUE IS DECREASED BY EMPLOYING BASE LOAD OPERATION TO RESTRICT OPERATING MANEUVERS'UTY ON THE APDNS.SYSTEM IS RELIEVED FUTURE T'ECHNICAL SPECIFICATION CHANGES ARE MINIMIZED BY REMOVING CYCLE DEPENDENT VALUES FROM THE TECH SPECS THESE CYCLE DEPENDENT VALUES ARE REPORTED TO THE NRC IN A PEAKING FACTOR REPORT

-- OPERATOR CONVENIENCE IS ENHANCED BY MAINTAINING A FORMAT SIMILAR TO THE UNIT 1 Fg TECH SPEC,
