Dear Sir or Madam:
In the Palisades Nuclear Plant (PNP) license renewal application (Reference 1),
Nuclear Management Company (NMC), the former license holder for PNP, committed to submit an equivalent margins analysis (EMA) for Nuclear Regulatory Commission (NRC) approval at least three years before any reactor vessel beltline material Charpy upper-shelf energy (USE) decreases to less than 50 ft-lb, in accordance with 10 CFR 50 Appendix G, Section IV, Fracture Toughness Requirements.
In Reference 2, Entergy Nuclear Operations, Inc. (ENO) submitted the required EMA under 10 CFR 50.4, Written communications, as required by 10 CFR 50 Appendix G. In Reference 3, ENO received a request for additional information (RAI) concerning the EMA submittal. The ENO response to RAI questions 1, 3, 4, 5, and 6 was provided in in Reference 4. The ENO response to RAI question 2 was provided in Reference 5.
During a conference call with ENO on October21, 2014, the NRC requested that the EMA be submitted under 10 CFR 50.90, Application for amendment of license, construction permit, or early site permit, rather than under 10 CFR 50.4.
As requested, ENO submitted the EMA under 10 CFR 50.90 in Reference 6.
Therefore, by this letter ENO is withdrawing the EMA submitted under 10 CFR 50.4 in Reference 2.
This letter contains no new commitments and no revised commitments.
Sincerely,
