In Reference 1, the Nuclear Energy Institute (NEI) provided the U. S. Nuclear Regulatory Commission a resolution plan for the U. S. Nuclear Industry to address the known Anchor Darling Double Disc 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 inform ation , 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 Indiana Michigan Power Company (l&M), the licensee for Donald C. Cook Nuclear Plant Units 1 and 2.
The Enclosure to this letter contains the following information for each ADDDGV.
- Plant Name, Unit, and Valve ID
- System I* "
J
U. S. Nuclear Regulatory Commission AEP-NRC-2017-59 Page 2
- Valve Functional Description
- Valve Size
- Active Safety Function (open , close, both)
- Are multiple design basis post-accident strokes 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 112, Revision 4 (Reference 3)?
- Does the susceptibility evaluation rely on thread friction? If yes , was the coefficient of friction greater than 0.1 O? For cases where thread-friction was relied upon, information is provided whether the coefficient of friction was above or below 0.10.
- Was an initial stem-rotation check performed? If yes , include rotation criteria (i.e. :s; 1Q degrees or ::;;5 degrees).
- Was the diagnostic test data reviewed for failure precursors described in TP16-1 -112, Revision 4 (Reference 3)?
- The valve 's repair status (i.e. repaired or not repaired)
- A repair schedule for each susceptible valve There are no new regu latory commitments made in this letter. Should you have any questions or require additional information , please contact Mr. Michael K. Scarpello, Regulatory Affairs Manager, at (269) 466-2649.
