Dear Sir or Madam:

Entergy Nuclear Operations, Inc, (Entergy) requested a License Amendment, Reference 1, to Operating 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 the Refueling Water Storage Tanks (RWST) seismic piping by manual operation of a RWST seismically qualified boundary valve under administrative controls for a limited period of time. On October 2, 2012 the NRC staff identified the need for additional information to complete their review (Reference 2). Entergy is providing additional information in response to this request (see Attachment).

There are no new commitments being made in this submittal. If you have any questions or require additional 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 in accordance with 10 CFR 50.91.

NL-12-143 Docket 50-286 Page 2 of 2 I declare under penalty of perjury that the foregoing is true and correct. Executed on October 25, 2012.

Sincerely, JAV/sp

INDIAN POINT NUCLEAR GENERATING UNIT NO. 3 DOCKET NO. 50-286

NL-12-143 Docket No. 50-286 Attachment Page 1 of 1 The NRC reviewed Letter NL-12-090, dated August 14, 2012 proposing a License Amendment and requested additional information as follows:

Request For Information The valves that are mentioned in Attachment 1 of the Reference, Section 4.0, "Technical Evaluation," are credited with closure to isolate the non-seismic portion of the RWST Purification System. Are these valves within the scope of the Indian Point 3 American Society of Mechanical Engineers (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 these valves? If not, what is the justification for exempting them from the IST Program?

Response

When 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 likely due to their limited use. After reviewing the function of these valves, it was determined that they should be added to the U3 IST Program. Condition Report IP3-2012-03339 was generated to correct this. Per the ASME OM Code (ISTC-3540), manual valves are required to be tested every 5 years. The Unit 3 ASME OM Code (IST) Program will be updated prior to their usage. Since these valves are full-stroke exercised every two years during system usage, the intent of the IST Program has been met and will be credited. Therefore, there is no IST Program requirement to stroke 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 to past usage.
