QCNPS Regulatory Commitment Change Summary Report June 1, 2010- May31, 2011 Commitment Change Tracking Number: 10-01 Source Document: J. Hosmer letter to USNRC dated March 15, 1997 (GL 96-05)

Change Approved On: 9/22/2010 Original Commitment Description Per Quad Cities response to Generic Letter (GL) 96-05 and the resulting NRC Safety Evaluation Report (SER), the station committed to all phases of the Joint Owner's Group (JOG) Program on periodic verification of MOV performance (as documented in MPR 1807, "Joint BWR, Westinghouse and Combustion Engineering Owners' Group Program on Motor-Operated Valve (MOV)

Periodic Verification"). As a requirement of the JOG Program, periodic verification testing of MOVs shall not exceed 10 years.

Revised Commitment Description The periodic verification test for the 1-1402-24A, 1A Core Spray (CS) Pump Upstream Isolation Valve, can exceed 10 years on a one time bases to allow the test to be performed during QI R21 versus online.

Justification For Revision The 1-1402-24A valve is considered a Low Risk / High Margin valve. As such, the maximum 10 year periodic verification test interval was assigned to the valve. All other preventive maintenance (PM) activities have been performed as required. The actuator grease inspections and electrical checks have been routinely performed with satisfactory results. The valve packing checks and stem lube inspections have also been routinely performed with satisfactory results. In addition, all periodic stroke times for the valve have been consistent and the as-left LLRT from the previous outage was near zero (0.28 SCFH). Based on the results of the PMs and surveillance tests that are routinely performed on the valve, it can be concluded that the 1-1402-24A will remain capable of performing all of its design functions for the remaining five months between the current test interval end date and the proposed Q1R21 test date.
