Medical isotopes are a long-term possibility.
The Tesseract TGR is designed for industrial heat and firm power. Thorium fuel cycles produce small quantities of thorium-229, a parent of actinium-225, which is used in targeted cancer therapy. For Thorium Atomics, actinium-225 and other medical isotopes are at most a long-term possibility for the fuel cycle.

No isotope program.
Thorium Atomics has no design, program or agreement for isotope production. The engineering, licensing and commercial case for the reactor rests on industrial heat and firm power.
Accelerator production of actinium-225 is now routine, with NorthStar supplying it since January 2026.
