Dear Sir or Madam:

The purpose of this letter is to request the retraction of Entergy's "Request for Relaxation from NRC Order EA-12-049" (Reference 1).

On January 28, 2015, Entergy Nuclear Operations, Inc. (Entergy) submitted a request for relaxation (Reference 1) from the requirements of NRC Order EA-12-049 (Reference

2) for Indian Point Unit 3 (IP3).

As stated in Reference 1, the relaxation was requested due to the possibility that implementation of Order EA-12-049 could not be achieved, i.e., the Reactor Coolant Pump seal leak off line orifice might not be successfully installed during the Spring 2015 IP3 refueling outage (3R18).

The installation of the orifices on the seal leak off lines have gone as planned during the IP3 3R18 outage, and the seal leakage rate calculations developed by Westinghouse for the seal leakage model have been successfully completed and accepted by Entergy.

NL-15-036 Docket 50-286 Page 2 of 2 Final resolution of the leak off of RCP seals identified in Westinghouse Nuclear Safety Advisory Letter (NASL) 14-1 is still ongoing between the NRC and the Industry. Any new information that would require a revision to our strategies will be entered into our corrective action program.

This letter contains no new regulatory commitments. Should you have any questions regarding this submittal, please contact Mr. Robert Walpole, Manager, Regulatory Assurance at (914) 254-6710.
