On August 25, 2025, a historic step was taken in Covert Township, Michigan: The previously decommissioned Palisade nuclear power plant officially transitioned from decommissioning to operational status. The U.S. Nuclear Regulatory Commission (NRC) approved Holtec’s license package on July 24. Palisade thus made history, as it was the first time in the United States that a decommissioned nuclear power plant was successfully brought back into operation. This achievement is considered a milestone for the American energy supply and simultaneously strengthens stability in Michigan. (holtecinternational: 26.08.25)
Focus on safety and energy supply
With the renewed approval, Palisade is permitted to store fuel and start up the plant as soon as all technical specifications are met. The emergency response plan is fully activated. A trained response team recently successfully completed an exercise evaluated by FEMA and the National Renewable Energy Corporation (NRC). In close cooperation with state and regional authorities, this has created resilient structures for crisis situations.
The restart is in its final phase. Inspections, testing, and maintenance are under strict federal supervision. Once reconnected to the grid, the nuclear power plant will generate more than 800 megawatts of baseload electricity. This output is sufficient for over 800,000 homes and businesses. In addition to the immediate benefits for Michigan, this step also signals a strong commitment to nuclear energy as an essential pillar of America’s energy supply.
Progress on the Palisade Turbine and Generator
Numerous projects still need to be completed before the start-up. This includes work on the steam generators. The primary-side repairs involving tube sleeves and plugs have been completed. A thorough cleaning of the secondary systems is currently underway. These measures ensure reliable and long-term stable performance.
The restart of the main generator and turbine is particularly complex. After comprehensive tests on the rotor and stator, the 183-ton rotor was assembled. The work required precise preparation and the utmost care. Strict controls for foreign matter prevented any risks. These steps were complemented by maintenance and test runs of the emergency diesel generators and the installation of a modernized motor for the primary coolant pump. Palisade is thus setting standards for technical quality and safety in nuclear power.
Teamwork at the highest level
Over 600 permanent nuclear engineering specialists and approximately 1,000 external specialists are working on site. All operating personnel are fully licensed. This enormous team strength underscores the scale of the project and reflects the determination to successfully implement this historic restart. This project also sets a precedent for the future of energy supply, with an impact far beyond Michigan.
Paving the Way for SMR Reactors
The restart of Palisade has a second dimension. It paves the way for the construction of innovative SMR reactors at the site. The plan is to build two compact units, each with a capacity of 300 megawatts. Commissioning is scheduled for the beginning of the next decade and is intended to permanently strengthen Michigan’s energy supply.
So far, preparations have been limited to geotechnical investigations and initial work on the construction site. The actual construction will be carried out in partnership with Hyundai Engineering & Construction, which recently completed the four reactors at the Barakah plant in the United Arab Emirates. With this combination of experience and technical innovation, the nuclear power plant is positioning itself as a symbol of change in global nuclear energy and a pioneer for the introduction of modern SMR reactors.
