Background===

On July 25, 2016, the NRC staff issued RAI SET 2016-01 in NRC Agencywide Documents Access and Management System (ADAMS Accession No. ML16138A194), requesting additional information pertaining to License Renewal Interim Staff Guidance, LR-ISG-2012-02, Aging Management of Internal Surfaces, Fire Water Systems, Atmospheric Storage Tanks, and Corrosion Under Insulation. By letter dated December 2, 2016, Entergy responded to RAI SET 2016-01 (ADAMS Accession No. ML16350A005). Based on its review of the information contained in Entergys letter, the NRC staff issued follow-up RAIs by letter dated March 8, 2017 (ADAMS Accession No. ML17046A231). On March 15, 2017, NRC and Entergy staff held a clarification call to ensure that Entergy clearly understood what the staff was requesting in the follow-up RAIs.

The follow-up RAIs are listed below and can be found in the ADAMS under Accession No. ML17046A231.

RAIs RAI 3.0.3-9a RAI 3.0.3-9b RAI 3.0.3-10-1a RAI 3.0.3-10-2a RAI 3.0.3-10-6a RAI 3.0.3-10-7a RAI Discussion RAIs 3.0.3-9a and 3.0.3-9b Subsequent to the applicant stating that they had no follow-up questions on RAI 3.0.3-9a and 3.0.3-9b, the staff emphasized the following points: (a) the basis of RAI 3.0.3-9a is that the staff believes that for the leak that had available wall thickness measurements, it would appear that structural integrity requirements could have been met on the day of the leak; (b) the thrust of request (1) is confirmation of this assumption or obtaining enough information to demonstrate that structural integrity would not have been met; (c) if structural integrity would have been met, then structural integrity should not be used as an acceptance criteria for wall thickness measurements; and (d) staff does not have a concern with the number of periodic inspections, periodicity, and the number of augmented inspections if adverse results are encountered.

The applicant indicated that the question is clear.

RAI 3.0.3-10-1a The applicant asked to discuss the level of detail that the staff expected for the requested changes to the service water integrity program. The applicant had limited its previous responses to those that required the program document itself to be modified. The staff discussed the circumstances surrounding the relief request cited in the RAI to provide context

for issues related to the potential need for improvements in nondestructive examination techniques or service life predictive methodology. The applicant stated that they had previously considered those types of changes as individual corrective actions as opposed to changes to the program, but with that clarification they understood the level of detail that the staff was expecting. The applicant did not ask the staff to make any changes to the RAI wording.

RAI 3.0.3-10-2a The applicant stated, with the clarification discussed for the previous RAI regarding the level of detail, that they did not need any further discussion. The applicant did not ask the staff to make any changes to the RAI wording.

RAI 3.0.3-10-6a The applicant stated that they did not need any further discussion for this RAI, and they did not ask the staff to make any changes to the RAI wording.

RAI 3.0.3-10-7a This RAI was not discussed during the call.

RAI Response Date The letter that contained these follow-up RAIs requested a response from Entergy no later than 30 days from the date of the letter (i.e., response by April 8, 2017). During the call, Entergy requested 60 days to respond to the follow-up RAIs. The basis for the request is due to the applicant having entered an outage at Indian Point 3 outage on 3/13/17. The Subject Matter Expert (SME) is focusing on outage tasks and is working night shift, focusing on service water piping inspections (Visual and non-destructive examination (NDE)), service water heat exchanger inspections, including Containment Fan Cooler Units (FCU), eddy current inspections of Balance of Plant systems, structures, and components (SSCs) & FCUs, Main Condenser inspections, and engineering field support. The SME is needed to participate in both the outage and RAI response preparation and review. He has the detailed knowledge of the involved systems and the data to ensure the response is of high quality and validated.

The Director of the Division of License Renewal reviewed and approved Entergys request for a 60-day response.

Commitment Table By letter dated January 17, 2017 (ADAMS Accession No. ML17023A209), Entergy submitted an update to the list of commitments associated with the Indian Point license renewal review. The staff discussed the list with Entergy to ensure that the implementation dates were still appropriate in light of the recent agreement to shorten the period of extended operation for the units. All agreed that no change to the implementation dates was needed at this time.
