Anchor Darling Double Disc Gate Valve Information and Status

==References:==
: 1) Letter from Greg Krueger (NEI) to John Lubinski (U.S. Nuclear Regulatory Commission), Anchor Darling Double Disc Gate Valve Industry Resolution Plan Update (Project 689), dated August 4, 2017
: 2) Letter from Joe Pollock (NEI) to Brian Holian (U.S. Nuclear Regulatory Commission), NSIAC Concurrence on Anchor Darling Double Disc                      i Gate Valve Industry Response Actions (Project 689), dated October                i-26,2017
: 3) BWROG Topical Report TP-16-1-112, Revision 4, Recommendations to Resolve Flowserve 1OCFR Part 21 Notification Affecting Anchor Darling Double Disc Gate Valve Wedge Pin Failure In Reference 1, the Nuclear Energy Institute (NEI) provided the NRC a resolution plan for the U.S. Nuclear Industry to address the known Anchor Darling Double Disk Gate Valve (ADDDGV) issues. Reference 2 indicated each utility will provide a listing of their Anchor Darling valve population with active safety functions along with relevant valve information, including the results of susceptibility evaluations, repair status, and a repair schedule for each susceptible valve not yet repaired. This letter serves to provide this information for Salem Generating Station, Units 1and 2.
The Attachment to this letter contains the following information for each ADDDGV:
* Plant Name, Unit, and Valve ID.
* System.
* Valve Functional Description.
* Valve Size.
* Active Safety Function (open, close, both).

LR-N17-0192 Page 2
* Are multiple design basis post-accident strokes are required (yes/no).
* Expert Panel Risk Ranking (high, medium, low).
* Result of susceptibility evaluation (susceptible or not susceptible).
* Is the susceptibility evaluation in general conformance with TP16-1-112R4 (Reference 3)?
* Does the susceptibility evaluation rely on thread friction? If yes, was the COF greater than 0.1 0? For cases where thread-friction was relied upon, information is provided whether the coefficient of friction was above or below 0.1.
* Was an initial stem-rotation check performed? If yes, include rotation criteria (i.e.
:510 degrees or :55 degrees).
* Was the diagnostic test data reviewed for failure precursors described in TP16        112R4 (Reference 3)?
* The valve's repair status (i.e. repaired or not repaired).
* A repair schedule for each susceptible valve.
There are no regulatory commitments in this letter.

NOTES:
: 1. The Repair method for the MOV's includes replacing the stem with a new stem with a Integral collar, torquelng the stem/wedge connection to 120 percent of the maximum anticipated design basis operating torque (assuming a 0.20 COF), and pinning the connection with new lnconel718 pins.
: 2. For all MOVs which required thread friction to validate the current operational capability, PSEG plans to repair all18 valves lAW the schedule above (within the next two refuel outages at each unit)
: 3. For the remaining 14 MOVs which screened out as acceptable based on PIN shear capability alone, PSEG plans to monitor using normally scheduled diagnostic testing and stem rotation checks per the MOV program requirements lAW NRC GL 96-05.}}
