Dear Sir or Madam:

In Reference 1, Entergy Nuclear Operations, Inc. (ENO) notified the NRC that, for resolution of Generic Safety Issue -191 (GSI-191) at Palisades Nuclear Plant (PNP), it had selected for the risk-informed version of Option 2 in Commission Paper SECY-12-0093, "Closure Options for Generic Safety Issue - 191, Assessment of Debris Accumulation on Pressurized-Water Reactor Sump Performance," dated September 13, 2004.

In Reference 2, ENO submitted a schedule for GSI-191 resolution. In Reference 3, a public meeting notice was issued to summarize a meeting ENO held with NRC to discuss the status of the PNP GSI-191 project.

. In Reference 4, ENO submitted a certification of permanent cessation of power operations with a shutdown date of October 1, 2018. In Reference 5, NRC issued a closure letter for GSI-191 citing the planned shutdown date of October 1, 2018 for PNP. In Reference 6, ENO notified the NRC that PNP would continue operation and changed the date that PNP will permanently cease power operation from October 1, 2018 to the spring of 2022. This notification was supplemented in Reference 7, which notified the NRC that PNP will permanently cease power operation no later than May 31,2022.

Due to the postponed shutdown date for PNP, ENO is providing a revised schedule for GSI-191 risk-informed resolution at PNP in Attachment 1.

Summary of Commitments This letter contains no new commitments and no revisions to existing commitments.
