Will the NRC approve early construction work for Holtec's Pioneer small reactors at Palisades by June 30, 2027?

Holtec plans two SMR-300 reactors, Pioneer 1 and 2, next to Palisades. It has asked the NRC for a limited work authorization to start site and foundation work before a full construction permit, and expects the NRC's draft safety evaluation in December 2026.

How this question entered the record and how it will be resolved.

Resolution criteria

Resolves Yes if, on or before June 30, 2027, the NRC issues a limited work authorization or a construction permit for Pioneer Units 1 and 2 at the Palisades site, as shown on nrc.gov or in the Federal Register. Resolves No otherwise. Exemptions for preparatory work, such as the August 2026 excavation exemption, do not count.

Expected resolution

Jun 30, 2027

• World Nuclear News, October 2, 2026: Holtec says the NRC draft safety evaluation for the limited work authorization is anticipated in December 2026
• NRC issued TVA's Clinch River SMR construction permit after a 14 month review (September 2026)

A draft safety evaluation is not a decision, and the NRC still needs an environmental review. Holtec's attention and money are also tied up in the troubled Palisades restart.
