Overview
- Radiant purchased portions of the former K-27 and K-29 parcels from the Oak Ridge Industrial Development Board for a factory it will call R-50.
- Construction is slated to begin in early 2026, with reactor testing planned in 2026 and initial customer deployments targeted for 2028.
- The company says output will start with the first factory-built Kaleidos generator in 2028, with plans to scale from multiple units per year to as many as 50 annually in later years.
- Radiant will invest about $280 million and create 175 jobs in Roane County, supported by Tennessee’s Nuclear Energy Fund.
- Designed as a 1‑megawatt portable power source for remote and mission-critical sites, the Kaleidos microreactor still requires federal regulatory approval.
