NRC Preparing to Oversee First of a Kind Effort to Restart a Shuttered Plant
The Palisades Nuclear Plant (PNP) permanently ceased operations on May 20, 2022, after more than 40 years of commercial operation. In early 2023, Holtec, the licensee for PNP expressed an interest in returning the plant to an operational status.
To restart PNP, Holtec would need to (1) gain NRC approval to restore the licensing basis of the plant to an operational status; (2) return plant components to a status that supports safe operation; and (3) make any upgrades necessary to meet the proposed operational licensing basis.
NRC staff will carefully review the regulatory and licensing documents for the plant, inspect new and restored components necessary to operate safely, and continue ongoing oversight to ensure sufficiency of all plant systems and programs.
To provide oversight of this effort, the NRC has established the Palisades Nuclear Plant Restart Panel, which will guide the staff efforts to review, inspect, and confirm that PNP is ready to be returned to an operating facility. The Restart Panel will help coordinate licensing, inspection, and oversight activities across the agency to ensure that all aspects of the PNP restart project are meeting the NRC’s safety, security, and environmental requirements.
Licensing Actions Under Review
The licensee for the Palisades Nuclear Plant, Holtec Decommissioning International (HDI), is pursuing several licensing actions to restore the operational licensing basis for the plant.

The NRC recently issued a letter to Holtec informing the licensee of the new estimated NRC staff hours and completion dates necessary for the various licensing actions outlined above due to the additional effort and time required by the NRC staff to complete its review of the environmental impacts from the proposed licensing actions related to reauthorization of power operations at Palisades. The NRC staff now expects to issue its final decisions on the licensing actions by July 31, 2025. The schedule change letter is available for public review at ADAMS Accession No. ML24219A420.
Inspection Activities
Numerous NRC inspections and other oversight activities are planned to assess Holtec’s readiness to restart the Palisades plant. In support of this effort the NRC established Inspection Manual Chapter (IMC) 2562, “Light-Water Reactor Inspection Program for Restart of Reactor Facilities Following Permanent Cessation of Power Operations.” The purpose of IMC 2562 is to:
- Establish oversight policies, requirements, and guidance for transitioning from a decommissioning reactor facility to an operational power reactor facility subject to the Reactor Oversight Process (ROP).
- Detail the requirements for the inspection activities and operational plant readiness to provide reasonable assurance for safe operations following reactivation of an operating license.
- Ensure other federal agencies, state and local governments, tribal governments, the public, and other applicable stakeholders are engaged and informed.
The NRC has assembled a site-specific inspection plan related to the oversight activities necessary to assess the effectiveness of Holtec’s actions related to the potential restart of Palisades in accordance with the NRC’s health, safety, and environmental standards. The series of inspections will provide input for developing an objective and documented basis for any NRC decision to transition Palisades back to the operating reactor inspection program and resume commercial power operations. The inspection plan is available for public review at ADAMS Accession No. ML24228A195.
Publicly available inspection reports from the activities completed to date related to the efforts to resume power operations at Palisades are listed below:
March 20, 2024 – Palisades Plant Reference Simulator Inspection Report
July 15, 2024 – Palisades Nuclear Plant – Restart Inspection Report 05000255/2024011

Public Meetings
The NRC has engaged in several pre-submittal interactions with the Palisades staff on various topics related to the potential for restart, and will continue to host public meetings related to the potential for Palisades to resume power operations throughout the project.
On Wednesday, April 17, 2024, the Palisades Restart Panel hosted a public meeting in the vicinity of the Palisades site to discuss the NRC’s efforts related to regulation and oversight of the potential restart activities. The summary of that meeting is publicly available in ADAMS at ML24141A063.
On Thursday, August 1, 2024, an additional meeting was held between members of the NRC and Holtec Decommissioning International staff to discuss the status and progress of the potential restart project. The summary of that meeting is publicly available in ADAMS at ML24257A058.
On Thursday, October 3, 2024, members of the HDI and NRC staff presented to the Advisory Committee on Reactor Safeguards to discuss various aspects of the project related to potential reauthorization of power operations at Palisades. The transcript and presentations from that meeting are publicly available in ADAMS at ML24319A182.
On Thursday, October 24, 2024, a public meeting took place between the NRC staff and HDI to discuss the licensee’s plans to resume work at Palisades on NRC Generic Letter (GL) 2004-02 (ML042360586), "Potential Impact of Debris Blockage on Emergency Recirculation during Design Basis Accidents [DBAs] at Pressurized-water Reactors [PWRs]," which is associated with Generic Safety Issue (GSI)-191, “Assessment of Debris Accumulation on Pressurized Water Reactor Sump Performance.” Additional goals for the meeting were for Holtec to provide a summary of the Palisades GL 2004-02/GSI-191 activities completed prior to cessation of power operations and give an update on the closure plan if power operations are reauthorized. The summary of that meeting is publicly available in ADAMS at ML24311A165. In addition, on December 11, 2024, the licensee provided a Milestone Schedule for Generic Letter 2004-02 Remaining Actions.
On Wednesday, November 20, 2024, an additional meeting was held in the vicinity of the Palisades site to discuss the NRC's efforts related to inspection and oversight of the potential restart activities. The summary of that meeting is publicly available in ADAMS at ML24358A243.
On Tuesday, January 14, 2025, members of the HDI and NRC met to discuss HDI's plans to submit separate license amendment requests related to primary coolant system leak-before-break and steam generator sleeving for Palisades. A portion of the meeting was closed to the public as the material discussed contained proprietary information. The summary of that meeting will be made publicly available in ADAMS as soon as it is complete.
Continue to check the NRC Public Meeting Page for information on any additional meetings on the Palisades Restart Project and associated actions.
Additional Activities
- On April 9, 2024, HDI provided notice of a significant change to the Palisades decommissioning schedule outlined in the Post-Shutdown Decommissioning Activities Report (PSDAR). This change will defer removal of spent nuclear fuel and special nuclear material from the spent fuel pool to the Independent Spent Fuel Storage Installation (ISFSI). This change is being made to support the Palisades restart project but does not impact the current status of Palisades as a decommissioning facility.
- On April 18, 2024, HDI provided notice to the NRC of its intent to pursue subsequent license renewal as governed by 10 CFR 54, “Requirements for Renewal of Operating Licenses for Nuclear Power Plants.” According to the notice, HDI plans to submit an application for a second renewed operating license for Palisades during the first quarter of 2026 and no later than March 24, 2026. The first license renewal period for Palisades expires on March 24, 2031. Additional information regarding the NRC’s subsequent license renewal process can be found on the NRC’s public website under the Reactor License Renewal heading.
- On August 15, 2024, HDI provided notice regarding the transition of the payroll for site employees from HDI to its affiliate Palisades Energy, LLC. This transition was made effective August 14, 2024, to support the need to track PNP personnel costs separately from other employees to comply with the U.S. Department of Energy loan guarantee program requirements that govern the PNP restart project.
- On October 9, 2024, HDI requested recission of two previous exemptions related to the amount of onsite and offsite insurance coverage for PNP. The approved exemptions reduced the amount of coverage required for the facility considering its decommissioning status; therefore, rescinding the exemptions will increase the coverage levels to their previously required amounts.
- On December 4, 2024, HDI requested recission of three previous exemptions related to (1) allowing either a certified fuel handler or a licensed senior operator to approve the temporary suspension of security measures for Palisades during certain emergency conditions or during severe weather; (2) recordkeeping requirements during decommissioning; and (3) withdrawals from the Palisades nuclear decommissioning trust fund for spent fuel management and site restoration activities without prior notice to the NRC in the same manner that withdrawals are made for decommissioning activities. Rescinding the exemptions will reinstate the requirements in place during operation of Palisades.
-
Holtec International has stated its intention to request NRC approval to build small modular reactors (SMRs) at Palisades. The NRC is engaged in preapplication activities with SMR, LLC (A Holtec International Company) to construct and operate a dual unit facility of the SMR-300 design at the Palisades site. Details on the SMR-300 design, status of preapplication activities, and planned engagements may be found on the NRC’s
SMR-300 Pre‑Application Activities public webpage. Information on the SMR (Holtec) initial design, the SMR-160, may be found on the
SMR (Holtec) Designs public webpage.
