27780 Blue Star Highway, Covert, MI 49043 PNP 2025-087 10 CFR 26.9 December 31, 2025 ATTN: Document Control Desk U.S. Nuclear Regulatory Commission Washington, DC 20555-0001 Palisades Nuclear Plant NRC Docket No. 50-255 Renewed Facility Operating License No. DPR-20

Subject:

Supplement to Request for Additional Information Regarding Second Request for Exemption from Requirements of 10 CFR 26.205, "Fitness for Duty Programs -

Work Hours" By letter dated August 12, 2025 (Reference 1), in accordance with Title 10 of the Code of Federal Regulations (10 CFR), Part 26, Fitness for Duty Programs, Section 26.9, Specific exemptions, Palisades Energy, LLC (Palisades Energy) requested U.S. Nuclear Regulatory Commission (NRC) approval of a one-time exemption from the specific requirements of 10 CFR 26.205, Work hours. The proposed exemption, as supplemented by the letter dated October 15, 2025 (Reference 2), would allow the use of the less restrictive work hour limitations specified in 10 CFR 26.205(d)(4) and (d)(5) in lieu of the requirements of 10 CFR 26.205(d)(3) and (d)(7) for an additional 60-day period to support outage activities for restart of the Palisades Nuclear Plant (PNP).

On October 24, 2025 (Reference 3), the NRC granted the requested one-time exemption to use the less restrictive outage work hour controls in 10 CFR 26.205(d)(4) and (d)(5) for a period not to exceed 60 days to support restart activities during the period of the proposed exemption. The exemption period commenced on November 3, 2025 and will expire on January 1, 2026.

By letter dated December 12, 2025 (Reference 4), Palisades Energy requested a second request for a one-time exemption from the specific requirements of 10 CFR 26.205. This proposed exemption would allow use of the less restrictive outage work hour controls in 10 CFR 26.205(d)(4) for an additional period of 60 days, to commence on January 2, 2026, after a two week rest and reset period. The proposed exemption would apply to personnel performing duties specified in 10 CFR 26.4(a)(2) [Health Physics and Chemistry] and 10 CFR 26.4(a)(4) [Maintenance and Projects].

On December 22, 2025 (Reference 5), Palisades Energy received a Request for Additional Information (RAI) by electronic mail (email) regarding the second request for exemption from the requirement of 10 CFR 26.205. Palisades Energy provided the responses to the RAI on December 26, 2025 (Reference 6).

On December 30, 2025, the NRC staff and representatives of Palisades Energy held a clarification call to discuss the RAI response. The Enclosure to this letter supplements the previous RAI response as agreed during the call to provide additional descriptions and

PNP 2025-087 Page 2 of 3 provisions for managing and bounding cumulative fatigue. The attachment to the Enclosure provides three new commitments regarding the controls on work hours.

Palisades Energy requests approval of the exemption request no later than January 01, 2026 to support the ongoing activities that are critical for the successful completion of the current outage and restart of PNP.

Background===

By letter dated August 12, 2025 (Reference 1), Palisades Energy, LLC (Palisades Energy) requested U.S. Nuclear Regulatory Commission (NRC) approval of a one-time exemption from the specific requirements of Title 10 of the Code of Federal Regulations (10 CFR), 10 CFR 26.205, Work hours. The proposed exemption, as supplemented, would allow the use of the less restrictive work hour limitations specified in 10 CFR 26.205(d)(4) and (d)(5) in lieu of the requirements of 10 CFR 26.205(d)(3) and (d)(7) for an additional 60-day period to support outage activities for restart of the Palisades Nuclear Plant (PNP). The NRC granted the exemption on October 24, 2025 (Reference 2).

By letter dated December 12, 2025 (Reference 3), Palisades Energy requested a second request for a one-time exemption from the specific requirements of 10 CFR 26.205. This proposed exemption would allow use of the less restrictive outage work hour controls in 10 CFR 26.205(d)(4) for an additional period of 60 days. The proposed exemption would apply to personnel performing duties specified in 10 CFR 26.4(a)(2) [Health Physics and Chemistry]

and 10 CFR 26.4(a)(4) [Maintenance and Projects].

On December 22, 2025 (Reference 4), Palisades Energy received a Request for Additional Information (RAI) by electronic mail (email) regarding the second request for exemption from the requirement of 10 CFR 26.205. Palisades Energy provided the responses to the RAI on December 26, 2025 (Reference 5). Following submittal of the RAI responses, the NRC staff and representatives of Palisades Energy held a clarification call on December 30, 2025 to discuss the RAI response. As a result of the call, Palisades Energy agreed to supplement the RAI response. The supplemental information is provided in this Enclosure.

Supplement to Palisades Energy Response to RAI 1.a:

As understood in the clarification call conducted between the NRC and Palisades Energy on December 30, 2025, Palisades Energy hereby provides the following tables which include updated commitments for Tesco Projects, the Fuel Handling Equipment (FHE) project, and the Alloy 600 project. The tables also provide updated work schedules from November 3 to December 30, 2025, demonstrating cumulative average weekly hours for that period. Lastly, Palisades Energy has concluded that the covered individuals which were categorized under Framatome Projects have completed their scope of work and are not currently scheduled for future work. Therefore, the individuals categorized under Framatome Projects no longer apply to this exemption request.

Chemistry The majority of the individuals in the Chemistry department worked between 8 and 9-hour shifts for 5 consecutive days followed by 2 consecutive days off.

Additional days off were provided where practicable to support fatigue management.

This schedule was in compliance with 10 CFR 26.205(d)(1), (d)(2) and (d)(7),

and resulted in a cumulative average of 37.92 hours0.00106 days <br />0.0256 hours <br />1.521164e-4 weeks <br />3.5006e-5 months <br /> per week.

There are no current plans to increase work hours until primary system passivation activities commence. The date for the start of passivation is not yet determined.

The Chemistry department is currently observing a rest and reset period in which no individual will work more than 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> per week, averaged over the two-week span from 12/19/2025 to 01/01/2026.

Health Physics The majority of the individuals in the Health Physics department worked 12-hour shifts for 4 consecutive days followed by 1 day off.

Additional days off were provided where practicable to support fatigue management.

This schedule was in compliance with 10 CFR 26.205(d)(1), (d)(2) and (d)(4),

The Health Physics department does not plan to deviate from this work schedule during the proposed exemption period.

The Health Physics department is currently observing a rest and reset period in which no covered individual will work more than 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> per week, averaged over the two-week span from 12/19/2025 to 01/01/2026.

Summary As described in the Group 10 CFR 26.4(a)(2) table above, to support the ongoing PNP outage activities and subsequent plant restart, the covered individuals in Chemistry and Health Physics work different schedules. The schedules will remain in compliance with 10 CFR 26.205(d)(1), (d)(2), and (d)(4). To ensure an adequate reset before continuing outage activities, the individuals in this Group are currently observing a rest and reset period in which no covered individual will work more than 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> per week, averaged over the two-week span from December 19, 2025 through January 1, 2026.

The Group 10 CFR 26.4(a)(2) table includes the scheduled 30-minute shift turnover time as part of the work hour averaging calculation. This is conservative because shift turnover time may be excluded from the calculation of an individual's work hours (
