Donald C. Cook Nuclear Plant Commitment Change Summary October 25, 2014 through April 28, 2016 1

NOTIFICATION OF COMMITMENT TO IMPLEMENT ALL THREE PHASES OF THE JOINT OWNERS GROUP PROGRAM Commitment No: 7945 Classification: Revision Source Document: C0601-18 Original Commitment Statement:

Indiana Michigan Power (I&M) commits to the Motor Operated Valve (MOV) Joint Owners Group (JOG) Program with a one-time exception of 2-ICM-251 static diagnostic testing to exceed the periodic verification (PV) frequency interval to extend through the completion of the scheduled U2C21 refueling outage in 2013.

Revised Commitment Statement:

I&M commits to the MOV JOG Program with a one-time exception for 2-ICM-251 static diagnostic testing to exceed the PV frequency to extend through the completion of the U2C21 refueling outage and a one-time exception for 1-IMO-310 extension to October 31, 2015.

Change Description Summary:

The MOV JOG program dictates that static diagnostic test frequencies be set based on Table 7-14 in MPR-2524-A. Using the frequency criteria from MPR-2524-A, 1-IMO-310 has a PV frequency of 6 years.

As a result of an unplanned forced outage for diesel generator repairs, system conditions do not support performing the PV diagnostic test by the current due date of July 21, 2015. The affected work week window has been rescheduled for October 2015.

Current margins for 1-IMO-310 is 112% on the OPEN stroke and 258% for the CLOSE stroke.

1-IMO-310 is considered to have high margin. The PV diagnostic test validates the MOV has not degraded in performance since the last diagnostic test.

FINAL RESPONSE TO REQUEST FOR ADDITIONAL INFORMATION CONCERNING THE REACTOR VESSEL INTERNAL AGING MANAGEMENT PROGRAM Commitment No: 8607 Classification: Due Date Change Source Document: AEP-NRC-2014-60 Original Commitment Statement:

I&M will continue to participate in the Pressurized Water Reactor Owners Group (PWROG) project for lower support columns. I&M will provide a supplemental response to the Nuclear Regulatory Commission on this request for additional information when an acceptable methodology is developed by the PWROG project.

Revised Commitment Statement:

I&M will continue to participate in the PWROG project for lower support columns. I&M will provide a supplemental response to the NRC on this request for additional information when an acceptable methodology is developed by the PWROG project.

Change Description Summary:

The solution path for lower support columns is to create a generically applicable evaluation and/or plant specific work to show applicability of PWROG evaluations. Current projected completion date of project is May 31, 2017. Commitment due date will be changed to 3 months after completion of the PWROG project to allow time for I&M to generate a plant specific NRC submittal. The original due date for this commitment was March, 31 2015 changed to August 31, 2017.
