Entergy Letter NL-12-090 to NRC Regarding Proposed LicenseAmendment Regarding Connection of Non Seismic Purification Line toRefuel Water Storage Tank, dated August 14, 20122. NRC Letter to Entergy Request for Additional Information RegardingProposal to Align the Refueling Water Storage Tank and The Spent FuelPool Purification System (TAC No. ME9263), Dated October 2, 2012Dear Sir or Madam:Entergy Nuclear Operations, Inc, (Entergy) requested a License Amendment, Reference 1, toOperating License DPR-64, Docket No. 50-286 for Indian Point Nuclear Generating Unit No. 3(IP3). The proposed amendment would revise Technical Specification 3.5.4, to allow the non-seismically qualified piping of the Spent Fuel Pool (SFP) purification system to be connected to theRefueling Water Storage Tanks (RWST) seismic piping by manual operation of a RWSTseismically qualified boundary valve under administrative controls for a limited period of time. OnOctober 2, 2012 the NRC staff identified the need for additional information to complete theirreview (Reference 2). Entergy is providing additional information in response to this request (seeAttachment).There are no new commitments being made in this submittal. If you have any questions or requireadditional information, please contact Mr. Robert Walpole, IPEC Licensing Manager at (914) 254-6710. A copy of this response is being submitted to the designated New York State official inaccordance with 10 CFR 50.91.

Are these valves within the scope of the Indian Point 3 American Society of MechanicalEngineers (ASME) Code for Operation and Maintenance of Nuclear Power Plants (OM Code)Inservice Testing (IST) Program? If so, what are the owner-specified test requirements for thesevalves? If not, what is the justification for exempting them from the IST Program?ResponseWhen preparing this response, it was discovered that valves AC-725, AC-727A, AC-726B, AC-727B, and SI-841 had not been included in the last IST Program (4th Interval) update most likelydue to their limited use. After reviewing the function of these valves, it was determined that theyshould be added to the U3 IST Program. Condition Report IP3-2012-03339 was generated tocorrect this. Per the ASME OM Code (ISTC-3540), manual valves are required to be tested every5 years. The Unit 3 ASME OM Code (IST) Program will be updated prior to their usage. Sincethese valves are full-stroke exercised every two years during system usage, the intent of the ISTProgram has been met and will be credited. Therefore, there is no IST Program requirement tostroke these valves prior to their usage. Prior to its use this upcoming outage the check valve (AC-726B) will be closure tested as required by the IST Program prior to its use, as it has been prior topast usage.
