- 2) Letter from Joe Pollock (NEI) to Brian Holian, U.S. Nuclear Regulatory Commission, NSIAC Concurrence on Anchor Darling Double Disc Gate Valve Industry Response Actions (Project 689), dated October 26, 2017 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. Reference 2 also stated that utilities or sites without active safety function Anchor Darling DDGVs would also provide a response.
This letter serves to confirm that South Texas Project Units 1 and 2 do not use Anchor Darling DDGVs to support any active safety function.
There are no commitments in this letter.
