Project TETRA / TETRA-1 pilot at Texas A&M RELLIS

DOE names TETRA-1 at Texas A&M RELLIS; Terrestrial’s January 2026 agreement connects the pilot to IMSR technology. This announced demonstration is separate from the commercial RELLIS IMSR proposal. Pilot output is unknown. The worker-safety variance and OTA pathway do not establish reactor construction or operating permission.
