The U.S. Nuclear Regulatory Commission has warned Holtec International, the company racing to reopen the shuttered Palisades nuclear plant in Michigan, that it needs to fix a "chilled work environment" that has left some staff hesitant to raise safety concerns — a rebuke landing on a project the Trump administration has held up as proof that America can revive its nuclear industry.
In an October 13 letter, the NRC said the chilling effect was confined to two departments, supply chain and quality assurance, and that the plant overall maintained a safety-conscious work environment in which most personnel felt free to raise nuclear safety concerns without fear of retaliation. The agency is requiring Holtec to brief employees on the findings, commission an independent evaluation and submit a corrective action plan within 30 days, but says existing safeguards adequately protect plant safety and that, based on current information, the findings are not expected to delay the planned restart.
The warning follows a rockier year at the plant than the measured NRC letter alone suggests. A worker fell into the reactor cavity last year, ingested some water and was sent off-site for medical attention; radiation protection staff later detected 300 counts per minute in the worker's hair during decontamination. In August, a bundle of nuclear fuel rods tilted over during a refueling operation, delaying what was meant to be the first reopening of a shuttered U.S. reactor; the NRC says no radiation was released and has since cleared Holtec to retrieve the potentially compromised assembly. The regulator also disclosed that nine of the plant's 15 reactor operators failed an initial licensing exam administered in July and August, leaving only six individuals licensed.
A Symbol Under Strain
Palisades first went into service in 1971 and was decommissioned in 2022, before Holtec — a company that has never previously operated a nuclear power plant — secured a $1.5 billion Department of Energy loan in 2024 to finance its restoration, part of roughly $2.2 billion in government support for the project. Two other shuttered plants, Three Mile Island in Pennsylvania and Duane Arnold in Iowa, announced their own restart plans soon after Palisades began work, making it something of a bellwether for the administration's broader bet that reviving retired reactors can help meet AI-driven electricity demand.
The Trump administration has promoted nuclear power as a competitive edge in the AI race against China, slashing regulatory requirements and pledging to reverse what officials have called a culture of "risk aversion" at the NRC in order to accelerate projects like Palisades. Critics argue the string of incidents shows exactly the opposite risk: that financial and political pressure to move fast can strain safety culture at a plant with no operating track record of its own, even when, as here, regulators say the core safety system is still functioning.
Investor Enthusiasm Is Already Fading
The warning lands as Wall Street's appetite for nuclear has cooled sharply. More than $30 billion has been erased from the market value of five of the largest U.S.-listed nuclear energy companies — Oklo, Centrus Energy, BWX Technologies, NuScale and NANO Nuclear — over the past year, as doubts grow about the pace of AI-driven power demand. Holtec itself was forced last month to postpone a planned initial public offering that had been expected to raise $900 million and value the company at up to $10 billion.
None of that changes the timeline pressure Holtec is under to prove a decommissioned reactor can be safely brought back online, nor the administration's political investment in Palisades succeeding as a model for the rest of the industry. The NRC's letter adds a formal, if contained, safety finding to what had largely been an argument about financing and regulatory speed — and sets a 30-day clock on Holtec showing its corrective plan holds up.
