Anchor Darling Double Disc Gate Valve Information and Status

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.

Should you have any questions or require additional information, please contact Mr.

Justin Wearne at 856-339-1351.
