June 2025 collaboration with Ameresco (NYSE: AMRC). Site identification + project development + design + licensing + construction + operation. KEY structural feature: natural gas-fired energy bridge enables early electricity delivery during the 7-year nuclear construction window — IMSR-400's remote/isolated thermal-steam-electric systems uniquely support gas hybridization unlike LWR-based SMRs. Solves the "bridge to nuclear" problem for AI/data center customers needing power immediately.
December 2024 MOU to evaluate siting IMSR plants at decommissioned nuclear sites owned by EnergySolutions. Brownfield strategy: existing nuclear sites have grid connections, regulatory familiarity, community acceptance, and licensed nuclear infrastructure footprints.
Schneider Electric MOU: integration of IMSR plants into industrial power systems (signed 2024). Zachry Group MOU: IMSR site evaluations and engineering services (signed 2024). Together support the IMSR-400's positioning as the molten salt option for high-temperature industrial heat applications including chemical synthesis and process steam.
UK joint venture with Viaro Energy to develop IMSR plants for data centers and industrial applications. FID (final investment decision) target: 2030. Builds on UK Generic Design Assessment (GDA) progress for IMSR.
Selected as one of four SMR firms for Texas A&M's "Energy Proving Ground" SMR siting program at the RELLIS Campus. Provides a research-friendly first commercial deployment site adjacent to A&M's nuclear engineering programs.
Generation IV molten salt reactor. 442 MWt / ~195 MWe per Core-unit. Standard plant configuration: 2 Core-units = 390 MWe. Sealed factory-built Core-unit replaced completely every 7 years (factory production quality control; never opened on-site). Walk-away safe — no operator intervention, no powered mechanical components, no coolant injection required for upset conditions. Operates at high temperature for industrial relevance. Critical structural advantage vs Natrium/most advanced reactors: uses STANDARD low-enriched uranium, not HALEU — eliminates HALEU supply bottleneck.
Pre-SPAC Series B funding round. Specific terms not publicly disclosed at full detail. Brought Terrestrial through development phase ahead of October 2025 SPAC merger.
Selected for DOE Office of Nuclear Energy Fuel Line Pilot Program — supports comprehensive nuclear supply chain strategy. Builds on existing Advanced Reactor Pilot Program participation.
