UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 July 29, 2016 CHAIRMAN Mr. Paul Gallay Mr. James Bacon Riverkeeper 20 Secor Road Ossining, NY 10562
Dear Messrs. Gallay and Bacon:
On behalf of the Commission, I am responding to your letter of May 17, 2016, in which you express concerns regarding recent briefings that the Commissioners and their staffs received on the status of inspections at Indian Point Unit 2 regarding baffle-former bolts. You note that two briefings were conducted by the NRC staff on April 19, 2016, but that Riverkeeper, as a party to the ongoing license renewal proceeding, did not learn of the briefings until the NRC staff's counsel informed the Atomic Safety and licensing Board and the parties of the briefings on April 26, 2016. You state that the Commission should have provided the parties to the adjudication with notice of the briefings and an opportunity to attend or participate. You also request that the Commission provide any relevant Commission-generated documents that may not have been provided to Staff counsel. Finally, you request reasonable advance notice of, and opportunity to attend or participate in, any future Commissioner briefings relevant to the resolution of the issues in the proceeding, including future briefings related to baffle-former bolts at Indian Point.
The Commission performs dual roles, in that it has general supervisory authority over the staff's activities and also sits in a quasi-judicial capacity in adjudications. Those two roles are kept separate. The separation of functions rule, set forth in 10 C.F.R. § 2.348, protects the fairness and transparency of the agency's adjudicatory process by placing certain restrictions on communications between the Commission and the NRC staff who are involved in the technical review of an issue that is being adjudicated within a contested proceeding-in this case, the Indian Point license renewal adjudication. The separation of functions rule is designed to prevent off the record communications on the merits of contested issues; however, the rule is not intended to prevent the NRC staff from communicating to the Commission or individual Commissioners matters unrelated to the specific issue that is the subject of a contested proceeding. The staff's April 19 briefings on the baffle-former bolt inspections were limited to a description of the baffle plates and bolts, applicable regulatory requirements, and current status of the inspection results at Indian Point Units 2 and 3. No prohibited communications took place, as the matters at issue in the adjudication were not discussed.
Requests for agency documents such as the one you made in your letter are appropriately directed to the agency's Freedom of Information Act (FOIA) process. However, in response to a recent FOIA request the NRC has made public documents that are also responsive to your request; courtesy copies of those documents are provided here.
Finally . you request notice and an opportunity to attend future briefings of the Commission . The April 19 briefings were not "meetings" subject to the Sunshine Act because a quorum of Commissioners was not present for either briefing . As such, public notice was not required. The NRC will provide public notice of Commission meetings when required by law.
but the Commissioners may receive additional non-public briefings as part of their obligation to supervise the NRC staff. Because the Commission continues to sit in a quasi-judicial capacity in the Indian Point license renewal proceeding , any such briefing will not address disputed issues in the license renewal proceeding.
A copy of your letter and this response will be served on the parties to the Indian Point license renewal adjudication.

Updated Info on Indian Point Good morning all, Region I held a call with Indian Point management yesterday to discuss the current status of the baffle bolts. Because there were some related questions during the briefings earlier this week, I'm passing along the latest information.
Unit 2
- The specialized tool is onsite and being used to replace the baits
- Entergy plans to replace all 227 bolts that failed UT
- Current rate of replacement is 7-9 bolts per day
- The site will have access to the specialized tool for as long as needed Unit 3
- Site senior management (Site VP) indicated their intent to move up inspection of U3 to the 2017 outage (from 2019) o No formal public announcements or notifications about these plans have been made o Entergy needs to still line up resources to ensure the plan can be accomplished as desired I'll keep you informed as things progress. Please let me know if you have any questions.
- Thanks, Jeremy 1

Dear Commissioners:
We support and applaud your interest in the safety issues raised by recent inspections at Indian Point Unit 2, which showed that over one-quarter of the baftle-former bolts within the plant's reactor core are degraded or missing. The continued supervisory engagement of the Commissioners on this important issue - which is unprecedented in the history of foreign and domestic nuclear plant operations - is vital for ensuring the safe operation of both Indian Point nuclear facilities, which are located 24 miles north of New York City and in the most densely populated area surrounding any nuclear facility in the nation.
While we are heartened to know of the Commissioners' attention to these safety issues at Indian Point, we write to remind you that your supervisory activities must comply with NRC regulations for the fair conduct of NRC adjudicatory proceedin~ including the prohibition against ex pa11e conducts on relevant issues. See ~nerally 10 C.F.R. §§ 2.347, 2.348; 5 U.S.C. § 557. We are particularly concerned that on April 19, 2016, NRC Commissioners and/or their Senior Executive Staff received two briefings from NRC Staff about the recent inspections at Indian Point Unit 2 and the safety implications of these results for both Indian Point Unit 2 and Indian Point Unit 3. Although Riverkeeper is a party to the on-going relicensing proceeding for Indian Point and has relevant contentions pending before the agency, we did not learn of the briefinp until a week later via a letter &om NRC Staff counsel to the Atomic Safety and Licensing Board ("ASLB").
See Letter from NRC Staff Counsel Sherwin E. Turk to ASLB Judge Lawrence G.
McDade, et al. re: Entergy Nuclear Operations, Inc. (Apr. 26, 2016) (and two attachments thereto).
NRC Staff is a party and litigant in the Indian Point adjudicatory proceeding. S- NRC Stafrs Statement in Response to the Atomic Safety and Licensing Board's Order of February 3, 2012 (Feb. 8, 2012) (ML12039A298). Thus, contacts between NRC adjudicatory employees (including the Commission and its staff) and the NRC Staff are subject to the NRC's ex parte rules. See Philadelphia Electric Co.

NRC Commissioners May 17, 2016 Page2 Station, Units land 2), ALAB-785 20 NRC 848, 883 n.161 (1984). While certain communications solely between NRC adjudicatory employees and NRC Staff may be permissible (i.e., communications relating to generic issues or providing mere status updates), NRC Staff counsel's April 26 letter includes two attachments which suggest that NRC Staffs April 19 briefings covered more substantive issues that are directly relevant to Riverkeeper's pending contentions. See Memorandum from Jeremy S. Bowen to Houman Rasouli re: Summary of April 19, 2016 Briefings for the Commissioners on Indian Point Baftle Bolts (April 22, 2016); Briefing on Indian Point Baftle Bolt Inspections (April 19, 2016). Therefore, we respectfully submit that the Commission should have provided the parties to this proceeding with notice of the briefing and an opportunity to attend or participate.
We appreciate receiving from NRC Staff counsel the Staff-generated documents provided at the April 19 briefing. In order to ensure the full provision of available information regarding the briefings, we also request you to provide any relevant Commission-generated documents that may not have been provided to Staff counsel, including any transcripts, recordings, or summaries of the briefings.
Finally, we request you to provide reasonable advance notice of and opportunity to attend or participate in any future briefings of the Commissioners on important issues relevant to the resolution of the contentions at issue- including any assessments of the significance of the bolt failures at Indian Point Unit 2 and/or the implications for operational safety at both Unit 2 and Unit 3.
