(1) Letter, L. Hill (Boiling Water Reactor Owners Group) to US NRC, Submittal of TP16-1-112r4, Recommendations to Resolve Flowserve 10CFR Part 21 Notification Affecting Anchor Darling Double Disc Gate Valve Wedge Pin Failures, dated August 29, 2017 (Accession number ML17243A137)

Dear Mr. Holian:

On behalf of the nuclear energy industry, the Nuclear Energy Institute (NEI) 1 is providing confirmation that the NEI Nuclear Strategic Issues Advisory Committee (NSIAC) concurs with the submittal of active safety function Anchor Darling Double Disc Gate Valve (DDGV) information to the NRC by December 31, 2017.

Specifically, the industry will evaluate the population of active safety function Anchor Darling DDGVs for each site against the revised industry guidance (Ref 1) and provide information as delineated below.

Each utility or site will provide, via letter to the NRC, a listing of their active safety function Anchor Darling DDGV valve population with relevant valve information, including the results of the above evaluation to the industry guidance. Identification of valves considered susceptible will include the repair status. A repair schedule for each susceptible valve not yet repaired will be provided. In addition, utilities or sites with no active safety function Anchor Darling DDGVs will also provide a response stating such.

1 The Nuclear Energy Institute (NEI) is the organization responsible for establishing unified industry policy on matters affecting the nuclear energy industry, including the regulatory aspects of generic operational and technical issues. NEI's members include all entities licensed to operate commercial nuclear power plants in the United States, nuclear plant designers, major architect/engineering firms, fuel cycle facilities, nuclear materials licensees, and other organizations and entities involved in the nuclear energy industry.

Mr. Brian Holian October 26, 2017 Page 2 Guidance regarding the recommended priority and repair schedule is provided in the reference industry guidance. A template is being developed to facilitate consistent reporting of the above information.

NEI continues to coordinate with industry organizations to assure effective communications and completion of the NSIAC supported actions. We will also continue our interactions with the NRC to provide updates on the status of industry progress and address any identified concerns or information needs.

If you have any questions, please contact me or Greg Krueger, 202.739.8099; gak@nei.org.

Sincerely, Joseph E Pollock Vice President and Acting Chief Nuclear Officer Nuclear Energy Institute 1201 F Street NW, Suite 1100 Washington, DC 20004 www.nei.org P: 202.739.8114 M: 202.436.1556 F: 202.293.3451 E: jep@nei.org
