Palisades Restart: Regulators Cite Operator Failures and Chilled Culture

Workers at the Palisades nuclear plant in Michigan now operate under a formal regulatory directive to fix internal safety protocols. The Nuclear Regulatory Commission issued a warning letter to Holtec International, the company managing the site's restart, citing a work environment that discourages employees from reporting safety issues.

The NRC described the site atmosphere as a chilled work environment. According to the regulator, staff members have shown reluctance to voice safety concerns due to a fear of retaliation. This finding emerged from an inspection conducted in July, which was triggered by prior questions regarding safety awareness at the facility.

The regulatory action follows two distinct safety events at the plant. Last year, a contractor fell into the reactor cavity and swallowed water. Radiation protection staff decontaminated the worker, yet an incident report noted that 300 counts per minute were still detected in their hair. The individual was sent off-site for medical care following the exposure.

A second incident occurred in August when a bundle of nuclear fuel rods tilted over during a refueling operation. This mechanical failure delayed the timeline for what was expected to be the first restart of a closed nuclear reactor in the United States. The delay impacts the project's schedule, which has been a centerpiece of the administration's strategy to revive domestic nuclear production.

The NRC also flagged a high failure rate among trainee reactor operators. Nine of the 15 individuals who took the initial licensing examination administered in July and August failed the test. Only six people received operator licenses from that group. The regulator views this performance as a sign of deeper operational issues that Holtec must correct.

Holtec International has never operated a nuclear power plant before this assignment. The company has secured approximately $2.2 billion in government support for the Palisades effort. Critics of the project argue that the financial and political pressure to revitalize the industry, particularly in response to energy demand from artificial intelligence, increases the likelihood of accidents.

The Palisades project is part of a wider trend in the nuclear sector. Owners of two other plants, Three Mile Island in Pennsylvania and Duane Arnold in Iowa, announced restart plans soon after work began at the Michigan site. These facilities were previously slated for decommissioning.
