Request for Additional Information Related to Palisades Relief Request Number RR 5-7 (EPID L-2018-LLR-0139)

Attachments: RAI.docx

Dear Mr. Erickson:

By letter dated November 26, 2018, Entergy Nuclear Operations, Inc. (ENO) requested an alternative to the ASME Code Section XI requirements for the repair of reactor pressure vessel head penetrations (Relief Request Number RR 5-7) for the Palisades Nuclear Plant.

The U.S. Nuclear Regulatory Commission (NRC) staff is reviewing your submittal and has identified an area where additional information is needed to complete its review. Attached, please find a request for additional information (RAI).

A draft RAI was previously transmitted to you by email dated November 29, 2018. At your request, the NRC held a clarification call with ENO on November 30, 2018, to clarify the NRC staffs request. As a result of the call, the NRC staff made a slight revision to Request #2. To support the requested date for verbal authorization by December 5, the NRC requests that ENO provide a response to the RAI by December 3.

If circumstances result in the need to revise the requested response date, please contact me at (301) 415-1627.

Respectfully, Kimberly Green (301) 415-1627 kimberly.green@nrc.gov 1

REQUEST FOR ADDITIONAL INFORMATION ENTERGY NUCLEAR OPERATIONS, INC.

PALISADES NUCLEAR PLANT DOCKET NUMBER 50-255 EPID L-2018-LLR-0139 By letter dated November 26, 2018, Entergy Nuclear Operations, Inc. (ENO) requested an alternative to the ASME Code Section XI requirements for the repair of the reactor pressure vessel head penetrations (Relief Request Number RR 5-7) for the Palisades Nuclear Plant (Agencywide Documents Access and Management System Accession No. ML18330A131).

1. Please provide justification or an evaluation that demonstrates that primary water stress corrosion cracking would not cause the J-groove welds to degrade and become loose parts.

2. Please discuss whether the calculation of the available years of service for half-nozzle repairs in the reactor pressure vessel closure head is based on available reinforcement area due to crack growth into the reactor pressure vessel head. Provide a summary of this portion of the calculation, or alternatively, provide the calculation.
