10 CFR Part 21 Reporting of Defects for lntrol Positioner 890265-010 To whom it may concern:

This is a follow up letter related to Curtiss-Wright SAS (CW SAS} Report no. 48 submitted on June 6, 2019 regarding the lntrol positionerfailure discovered at the Shearon Harris Nuclear Plant on January 18, 2019.

As reported in the initial report, the failure has been isolated to internal corrosion discovered inside TL084N Operational Amplifier chips on the SL3EX Controller Board. The cause of the failure has yet to be determined; however CW SAS and Paragon Energy Solutions (PES} continue to investigate potential causes.

CW SAS will continue working with affected sites to provide guidance on additional testing, along with developing solutions that include replacement of suspect chips on the lntrol positioner control boards. To allow CW SAS to coordinate efforts on a site by site basis, this will be the final correspondence sent directly to the NRC on this matter. *

. Sincerely, Todd Johnson
