Facility Solutions Group contributed electrical, instrumentation, controls, and verification work to one of the first advanced reactor projects in the nation.

LOCKHART, Texas, Aug. 25, 2026 /PRNewswire/ -- Facility Solutions Group (FSG) today announced its role supporting Oklo Inc. on the Groves Isotope Test Reactor, which achieved first criticality on August 5, 2026. Groves became the fifth reactor authorized under the U.S. Department of Energy's Reactor Pilot Program to reach a controlled, self-sustaining nuclear chain reaction, and the first under the program to do so on private land.

The low-power test reactor establishes a foundation for domestic commercial isotope production and demonstrates how nuclear projects can be deployed on accelerated timelines in the United States.

FSG joined the project in April 2026, with Century Construction serving as general contractor. Tasked with electrical work, instrumentation, controls, testing, and verifying the systems that make a reactor function, much of the work was performed without decades of industry precedent to draw from.

"I'm proud of this team. Century and Oklo trusted FSG with work that was critical to the success of the project. On a first-of-a-kind effort like this, that trust isn't given lightly. Our team embraced that responsibility from day one," said Kris Price, Construction Manager at FSG.

Throughout construction and commissioning, FSG, Century Construction, Oklo, and the project engineers worked as a single integrated team.

The project reflects FSG's ability to deliver skilled electrical and systems work on complex, high-stakes facilities.
