Company Says Microreactor Factory Near Bar Nunn Could Bring High‑paying Jobs; Commissioners, Residents Seek More Details

Representatives for Radiant told the Natrona County Board of County Commissioners and members of the public that the company plans to site a microreactor manufacturing facility just north of Bar Nunn and that prototype testing is scheduled at Idaho National Laboratory in the first half of next year.

The company’s representative, Matt Wilson, said the site plan calls for an approximately $200 million facility built primarily with local contractors that would take about 18 months to construct. He said the company expects the factory to employ about 75 people on day one and to peak at roughly 250 jobs after four to five years.

Wilson told commissioners the company aims to have a working prototype tested and fueled at Idaho National Laboratory in the first half of 2026, and to begin commercial manufacturing by about 2028 if licensing and approvals proceed as planned. He said each microreactor produces about 1 megawatt of power and would run for roughly five years before returning to the factory for refueling.

Why it matters: county officials and residents said the proposal could mean local jobs and new industry for Natrona County, but they repeatedly asked for clear, public answers about safety, spent‑fuel handling, regulatory authority and what a proposed $25 million state or local infrastructure grant would actually pay for.
