Dear Sir or Madam:

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 Entergy Operation, Inc.

and Entergy Nuclear Operations, Inc.

_4,0 D (

rJf<{(_

CNR0-2017-00025 Page 2 of 3 The Attachment 1 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).

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 TP 16-1-112R4 (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 0.1.

Was an initial stem-rotation check performed? If yes, include rotation criteria (i.e. s1 O degrees or S5 degrees).

Was the diagnostic test data reviewed for failure precursors described in TP16-1-112R4 (Reference 3)?

The valve's repair status (i.e. repaired or not repaired).

A repair schedule for each susceptible valve.

The Attachment 2 to this letter contains footnotes associated with each valve and commitments for repair of the applicable valves.

This letter also serves to confirm that Palisades Nuclear Plant does not use ADDDGVs to support any active safety function.

Should you have any questions or require additional information, please contact Mr. John Giddens, Senior Manager, Regulatory Assurance, at (601) 368-5756.

One-Time Action Programmatic Repair or Outage Yes/No Yes/No Yes/No 7, 8 Yes - Note (7l Jan/Feb 2019 Yes No 7, 8 Yes - Note (7l Jan/Feb 2019 Yes No Applied Wedge Pin Torque based on maximum value from diagnostic test data Applied Wedge Pin Torque based on maximum actuator output torque (locked rotor)

Applied Wedge Pin Torque based on the limiting value of the spring pack capability or the valve/actuator weak link torque.

M0-1001-29B is a priority 1 based on being subject to flow induced vibration in which the disc pack is in a turbulent flow stream.

Recirculation suction valves are classified as safety related - pressure boundary only.

Anomaly noted in diagnostic test Repair of valve is based on availability of replacement parts Wedge pin analysis is based on valve being properly torqued during assembly.

Flowserve provided a letter confirming the torque value because their process had changed when valves were purchased in 2002, however no work documents could be provided by Flowserve.

Susceptible based on review of diagnostic trace. Not susceptible based on pin shear analysis and stem rotation Wedge pin shear analysis is in progress. Corrective action will be based on the results of this analysis.

Stem rotation was greater than 5 degrees Non GL96-0S MOV Valves are under review to potentially change their safety function and/or risk signifucance.
