Subject:

Reactor Internals Upflow Modification Indian Point Nuclear Generating Unit No. 3 Docket No. 50-286 License No. DPR-64

Dear Sir or Madam:

The purpose of this letter is to inform you of the status of the reactor internals upflow modification for Indian Point Unit No. 3 (IP3). Indian Point Unit No. 2 (IP2) Licensee Event Report (LER) 2016-004 reported the discovery during a scheduled refueling outage that commenced in March 2016 of degraded baffle-former bolts in the IP2 reactor vessel. Implementation of a project in the IP2 2018 refueling outage to convert reactor flow configuration from downflow to upflow to improve margin for the baffle-former assembly was reported as a corrective action in the LER. In Inspection Report 05000247/2016 and 05000286/2016002, it was stated that "Entergy also planned a long-term corrective action to convert Units 2 and 3 from a "down-flow" baffle configuration to an "up-flow" configuration ... " This is to inform you that an upflow modification for IP3 will not be installed in the upcoming IP3 refueling outage that begins in March 2017.

There are no new commitments made by Entergy contained in this letter. If you have any questions, please contact Mr. Robert Walpole, Manager, Regulatory Assurance at (914) 254-6710.

Sincerely, AJV/gd
