Dear Sir or Madam:

In Reference 1, Entergy Nuclear Operations, Inc. (ENO) requested Nuclear Regulatory Commission (NRC) approval of a proposed alternative described in relief request number RR 4-18 for the Palisades Nuclear Plant (PNP). The request was associated with the use of an alternative to the requirements of the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code, Code Case N-770-1, as conditioned by 10 CFR 50.55a(g)(6)(ii)(F)(1) and 10 CFR 50.55a(g)(6)(ii)(F)(3), dated June 21, 2011.KIR-~

PNP 2015-037 Page 2 In Reference 2, the NRC staff verbally authorized on March 12, 2014 the use of relief request RR 4-18 at PNP until the next scheduled refueling outage (1R24), currently scheduled to start in fall 2015.In Reference 3, a NRC safety evaluation detailing the technical basis for the verbal authorization was issued on September 4, 2014.Subsequent to Reference 3, a discrepancy was discovered in one of the calculations that supported relief request RR 4-18 (Reference 1).This submittal (1) requests approval of the proposed alternative described in the enclosed relief request number RR 4-21, which supersedes upon approval relief request number RR 4-18, and (2) dockets corrections of documentation that supported relief request RR 4-18.This submittal contains no proprietary information.

This letter contains no new commitments and no revised commitments.

Sincerely,ýr r7k k jah/jse
