Terra Innovatum - SOLO
Project Overivew
The U.S. Nuclear Regulatory Commission (NRC) is currently engaged in pre-application activities with Terra Innovatum as of January 2025. Terra Innovatum is developing its SOLO micro modular reactor design, intended to form the basis for a scalable modular energy platform from MWe to GWe-class. A SOLO unit is designed to deliver approximately 1MWe. The design features a solid heterogeneous composite moderator and is intended to accommodate both traditional zircaloy-clad low-enriched uranium (LEU) fuel or, when available, LEU+ and high-assay low-enriched uranium (HALEU) fuels. Heat removal is accomplished by helium gas which eliminates the need for water from the reactor coolant system. The reactor is intended to feature autonomous operation, on-line safeguards-by-design, and a defense-in-depth structure of radiological barriers with the intent to minimize or eliminate emergency planning zone (EPZ) requirements beyond the operational boundary.
