The US Nuclear Regulatory Commission has issued a warning to Holtec International regarding its handling of safety concerns at the Palisades nuclear power plant in Michigan. The regulatory action follows a period of operational difficulties at the site, which includes an incident where a contractor fell into a reactor cavity and a bundle of fuel rods nearly tipped over during refuelling.

The NRC specifically cited a “chilled work environment” at Palisades, stating that staff have become hesitant to raise safety concerns for fear of retaliation. Holtec is currently working to reopen the shuttered reactor, a project that aligns with President Donald Trump’s broader efforts to revitalize the nuclear industry.

Critics have linked the NRC’s warning to the intense financial and political pressures surrounding the push to use nuclear power to meet growing energy demands driven by artificial intelligence. These observers argue that the drive to restart reactors like Palisades may be increasing the risk of accidents. The NRC’s intervention highlights the regulatory scrutiny Holtec faces as it attempts to return the facility to service.
