CLARIFICATION TELECONFERENCE CALL RELATED TO ENTERGYS RESPONSE TO ISG-2016-01 LICENSE RENEWAL APPLICATION JUNE 8, 2017 The U.S. Nuclear Regulatory Commission (NRC or the staff) and representatives of Entergy held a telephone conference call on June 8, 2017, to discuss and clarify information concerning the license renewal application (LRA).

By letter dated May 19, 2017 (ADAMS Accession No. ML17145A288), Entergy Nuclear Operations, Inc. (Entergy) provided responses to NRC staff requests for additional Information (ADAMS Accession No. ML17088A327). Upon review of Entergys responses, the NRC staff determined that additional clarification was necessary. On June 8, 2017, the staff held a teleconference with Entergy to discuss the needed clarifications.

Entergy clarified that the visual inspections under the Steam Generator Integrity Program on channel head interior areas are consistent with LR-ISG-2016-01, Changes to Aging Management Guidance for Various Steam Generator Components. These inspections are intended to identify signs indicating cracking or loss of material is occurring (e.g., rust stains, gross cracking, distortion of divider plates, and cladding breach). The inspections also confirm the structural integrity of reactor coolant pressure boundary components such as channel heads and tubesheets. In addition, Entergy discussed the recent general visual inspection activities for the channel head interior areas and plans for future inspections.

The staff agreed that these inspections under Entergys program are consistent with the guidance in LR-ISG-2016-01 and can identify signs indicating cracking in divider plate assembles and tube-to-tubesheet welds and loss of material in channel heads and tubesheets (such as loss of material due to boric acid corrosion). The staff has no further concerns with adherence to LR- ISG-2016-01.
