DPR-58 INDIANA AND MICHIGAN ELECTRIC COMPANY DONALD C.
COOK NUCLEAR PLANT, UNIT 1 DOCKET NO. 50-315 INTRODUCTION By letter dated December 5, 1986, the Indiana and Michigan Electric Company (the licensee) submitted a proposed license amendment to the facility operating license for the Donald C.
Cook Nuclear Plant, Unit No.
1.
The proposal was to limit the hourly verification of the quadrant Power Tilt Ratio to twelve hours.
EVALUATION The current technical specifications require the quadrant Power Tilt Ratio (gPTR) to be verified within its limit at least once per hour until verified acceptable at 95% or greater rated thermal power.
The Unit 2 technical specifications limit the hourly testing for 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />; this change would make the units alike without having to be at 955 power.
We have reviewed the licensee's submittal and agre'e that verifying the OPTR is within its limit once per hour for 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> is sufficient to ensure that an undesirable OPTR no longer exists and that the powe~ does not have to be greater than 95K to do this verification.
This change will bring D.
C.
