ENCLOSURE 5 RESPONSE TO REQUEST FOR ADDITIONAL INFORMATION (RAI) 1 .d (MOV Performance Indicator Report for Cycle 20) to ULNRC-06410 Page 1 of 45 NET 20150022 July 16. 2015 To: Matt Hall Victor Thomas From: Mike Brenner Re: MOV Testing Program The attached 18 Month MOV Performance Indicator Report for Cycle 20 was prepared in accordance with the provisions of EDP-ZZ-0l 114, Motor Operated Valve Program Guide.

Key Accomplishments:

All of Callaways safety-related Motor Operated Valves (MOV) are properly set up and are in good working condition. There are no signs of adverse trends. Nominal operating parameters for Cycle 20 are documented in Attachment 1.

a) All rising stem MOVs with active safety related functions using a torque switch in their closing stroke are setup to exceed the 25% target margin with the exception of EGHVOI3O which has a closing stroke margin of 19%. Job 14511998 has been written to restore the margin to 25%. Having 25% margin allows a 4-cycle/6 year static testing (rather than DP testing) interval for periodic verification of operability.

5) All rising stem MOVs with active safety function using a limit switch to open and or close have positive margin.

c) All butterfly MOVs have had their torque switches jumpered or removed. These MOVs must have positive margin for opening and closing stroke with an active safety-related function. All butterfly MOVs meet the parameters required to: 1) eliminate the need for periodic differential pressure testing, and 2) utilize the 4 cycle/6 year interval for periodic verification of operability.

  • The results of testing performed on rising stem valves during cycle 20 confirms that there is no lubrication degradation of the stem-to-stem nut interface over the 18-month interval between maintenance.

1. Summary of Diagnostic Testing Performed to Date and a Recap of Testing Performed during Cycle 20
  • There are currently 144 valves in the MOV program. All 144 have been static baseline tested and 99 have been differential pressure tested.
  • During Cycle 20, a total of 31 Periodic Verification Tests were performed. This included 1 Baseline Test on EGHVOO1 1 following an actuator grease change-out, 1 Baseline Test on ALHV0005 following an actuator grease change-out and 1 baseline test on ALHV0009 following a valve inspection. All MOV diagnostic tests are now being documented as Periodic Verification Tests with the exception of partial tests to verify packing loads.

These are called Packing Force Tests.

  • During Cycle 20, a total of 18 Service and Inspect PMs were performed on GL 89-10 Program MOVs. 203 Actuator Gearbox and Motor Pinion Gearbox grease inspections were performed on safety-related; Program, MOVs and non-safety-related; Production MOVs.
2. Description of the Current Setup of all Safety-Related MOVs, in the Generic Letter 89-10 Program.
  • Attachment 1 provides a synopsis of the current setup of GL 80-10 Program MOVs.

At the end of Refuel 20:

  • All rising stem torque-controlled MOVs with a safety function to close as setup to meet the 25% margin requirement except EGHVO13O which has 19% closing stroke margin. Job 14511998 is scheduled for Refuel 21 to restore the margin to greater that 25%.
  • All rising stem limit-closed MOVs are setup with the required positive margin.
  • All quarter-turn/butterfly valves are setup with positive margin to close.
  • All MOVs use limit switch control for their opening stroke. All MOVs are setup with positive opening stroke margin.

This CAR is In-Process.

Significance Level 3: 5 o CAR 201303697; FCHVO3I2 motor running at approximately twice normal speed.

Problem Statement: During as-found motor-operated valve FCHVO312 testing under job 11513700 (obj) the motor was found to be operating at approximately twice the normal speed (dev) resulting in a failed post maintenance test, extended out of service time, and additional outage critical path duration (imp).

5. Summary of Trends Identified from Predictive Performance Reports No trends were identified in the Predictive Performance Reports (PPR). A copy of each PPR is attached to this report.
6. Actions to Improve Margin and Reduced Voltage Performance
  • Job 1451998 was written to improve the close margin for EGHVO13O. The close margin is 19%. The Callaway standard for this MOV is 25%.
  • Job 14001995 was written to improve the stem/stem nut coefficient for BGLCVO1J2E. The COF is 0.179. Callaway action is initiated at a COF of 0.15 or greater.
  • Breakers continue to be replaced under Modification 91-1 035 and MCC Buckets under modification 01-1003 resulting in improved reduced voltage performance.
7. Operating Experience Evaluated During Cycle 20
  • CAR 201301468; Anchor Darling/Flowserve Part 21 Problem Statement: Flowserve contacted Callaway regarding a Part 21 notification for a potential defect in Anchor Darling double disc gate valves, size 2.5 or larger. The wedge pin that serves to lock the threaded stem to upper wedge joint can shear if the actuator applies a torque that exceeds the torque applied to the assembly before the pin was installed. A pin failure results in a loss of stem to upper wedge joint integrity.

Extent of Condition: CAR 201300135 identified the following Anchor Darling double disc gate valves installed at Callaway:

o EGHVOO58 o EGHVOO59 o EGHVOO6O o EGHVO127 o EGHVOI3O o EGHVOJ3J All are safety related.

This CAR is Complete. No actions or jobs are documented. CAR 201400704.was generated to readdress the Part 21. This CAR has been completed; however, further action is still required as determined by information obtained in January 2015 at the Motor Operated Valve Users Group (MUG) meeting.

  • Evaluation Statement: Evaluate the applicability of operating experience ICES 304752 on motor-operated valve limit switch failure due to over-burnishing and subsequent oxidation-induced contact failure.

Action to Resolve Issue: Action laddresses the applicability to Callaway as determined by the valve team supervisor. This OE was discussed with a senior electrical technician and it was suggested that training/retraining on the use of burnishing tools might be appropriate at this time. This training would be an enhancement. TRRQ 201400565 has been initiated to evaluate the need for this training.

This CAR is Complete.

  • CAR 201306796; NRC IN 2013014; Potential Design Deficiency in MOV Control Circuit Evaluation Statement: At Limerick Generation Station, Motor-operated valves (MOV) could remain partially open following the initiation of an automatic isolation signal in response to a 5

to ULNRC-06410 Page 8 of 45 18 MONTH MOTOR OPERATED VALVE PROGRAM PERFORMANCE INDICATOR REPORT FOR CYCLE 20 design-basis LOCA when power is interrupted to the actuator of certain MOVs. In addition, the valve position lights could indicate the valve is closed when the actual position could be as much as 15% open. This is reported in the Nuclear Regulatory Commission Information Notice 2013-14. The purpose of this evaluation is to determine if this Information Notice is applicable at Callaway.

Action to Resolve Issue: At Callaway, interlock/permissive functions ate not provided through the limit switches within the Limitorque actuator. Open and closed indications are provided through the Limitorque switches. When a LOCA trip signal is activated, Callaway MOVs are de-energized and then load sequenced and receive their power from their emergency diesel generator buss. With power, the MOVs will continue toward their design-basis position. Power could be lost, but the MOV will continue towards design basis position when power is restored. When power is removed and the MOV has stopped motion due to inertia, it will not reposition itself because all safety-related MOVs at Callaway have a locking gear-set through the Limitorque actuator except for GSHVOO2O and GSHVOO21. These MOVs have an HBC gear box. The gear box provides the locking gear-set condition. The condition discussed in NRC IN 2013-14 is not applicable as-built at Callaway.

This CAR is Complete.

8. Planned Actins to Enhance the Callaway MOV Program
  • CAR 201402649 Improve Motor Operated Valve PM Basis Condition Descrittion: The Motor-Operated Valve PM Basis is wrong for numerous tasks and references.

The MOV PM Basis is being reviewed for errors and to improve the clarity of the document.

Following the PM Basis update, PM frequency will be optimized based on operating experience.

  • Improve Test Criteria Worksheets for MOV testing. Potentially combine the Test Criteria Worksheet and the Signature Analysis Report into one datasheet.
  • Easy Thrust Torque (EU) Sensors will be utilized on quarter-turn, butterfly MOVs to improve test results.
  • Enter Test Criteria Worksheets, UDS Test Records and Predictive Performance Reports into Document Room for revision control and Planner access without engineering support.
