A federal review has commenced on a $400 million proposal to build small nuclear reactors at Palisades nuclear plant. The U.S. Nuclear Regulatory Commission has already commenced the review on the proposed Pioneer 1 and Pioneer 2 units. Moreover, they would be among the first small modular reactors in the country. The planned SMR-300 models were designed to rely on natural forces like gravity and thermal circulation to cool their reactor cores.

This is based on remarks from Nick Culp, senior manager of government affairs and communications at Holtec Palisades. “Holtec’s small modular reactor is, we call it, ‘walk‑away safe,” Culp said. “That’s an industry expression to say that it is using the most advanced technologies in safety developed within the industry over decades. It has a very passive and simplified safety system.” The firm has already secured up to $400 million in federal funding and plans to have the Pioneer reactors in place in the early 2030s. Other nuclear restart projects include the Iowa nuclear power plant. Google agreed to reopen the Iowa nuclear plant with the largest renewable energy company in the US, NextEra. The aim is to primarily provide power to Google as the tech giant races to secure clean energy.

Outlook on the Small Nuclear Reactors at Palisades Nuclear Plant

The small nuclear reactors at Palisades nuclear plant is just a snip of the long nuclear history at the site. Its main reactor was shut down and began the decommissioning process in 2022. However, Holtec committed to restart the older reactor, receiving $1.52 billion in federal loan guarantees. It also received $1.3 billion from the U.S. Department of Agriculture, and $150 million from the state of Michigan to support the project.

The company plans for the older reactor to be live again by the end of this year. Culp said Holtec chose the Palisades location because of the state of Michigan’s support for nuclear energy. Moreover, he noted it is because co-locating the new reactors on the same complex as the existing plant will help streamline operations and workforce needs. Nonetheless, the plan has drawn sharp opposition from anti-nuclear advocates. Kevin Kamps, who calls the Palisades site “a grand nuclear experiment,” warns that any reactor could carry unacceptable risks.
