Positive talking points for Nuclear Electricity Generation, page-9

Ultra Safe Nuclear Corporation (USNC) announced that a technology breakthrough in its patented Fully Ceramic Microencapsulated (FCM) fuel allows a fuel geometry that results in both higher power and increased safety, enabling its Micro-Modular Reactor (MMR) to produce three times more power.

The MMR has previously been touted as a 15 MW thermal, 5 MW electrical high-temperature gas-cooled reactor, using TRISO (tristructural isotropic) fuel in prismatic graphite blocks and with a sealed, transportable core. The graphite blocks contain stacks of FCM fuel pellets. The helium-cooled reactor is fuelled once for its 20-year lifetime.

The company has now said the MMR can flexibly work with either high-assay low-enriched uranium (HALEU) fuel (with 19.75% enrichment) or low-enriched uranium (LEU) fuel (with 9.9% enrichment) and operate at various power levels from 10 MWt (3.3 MWe) to 45 MWt (15 MWe). This, USNC said, enables it to serve a range of customers with a single standardised design.

"To accomplish this update, USNC is successfully demonstrating breakthrough technologies in 3-D printing and advanced manufacturing of its patented FCM fuel," the company said. "These technologies allow the flexibility to produce unique geometry FCM fuel pellets. FCM further encases TRISO particles in silicon carbide, ensuring that the helium coolant remains free from contamination. This advancement reduces thermal stresses on the fuel and enables increases in the output temperature and power of the MMR."
