Terrestrial Energy Inc's Comment on Competition and Industry Peers

The IMSR Plant competes with other Generation IV nuclear technologies, including molten salt reactors (MSRs) that typically use high-assay low-enriched uranium (HALEU) fuel, whereas the IMSR Plant uses standard-assay low-enriched uranium (SALEU) fuel. Competitors had anticipated sourcing HALEU from Russian suppliers prior to geopolitical changes that limited this supply. The IMSR Plant's use of SALEU aligns with existing fuel supply frameworks, which may facilitate earlier commercialization and reduce supply chain risks. Other competing nuclear technologies include high-temperature gas reactors (HTRs) and sodium fast reactors (SFRs). The IMSR Plant employs patented technology that distinguishes it from public domain MSR technologies used by other developers, who face operational challenges addressed by the IMSR design. The broader competitive landscape also includes traditional baseload electricity and thermal generation technologies such as fossil fuels, renewables (hydroelectric, wind, solar with storage), and other nuclear technologies.
