Modular Energy for a Demanding Grid.

General Atomics Electromagnetic Systems’ (GA-EMS) Fast Modular Reactor (FMR) is a 44-megawatt electric (MWe) advanced high- temperature gas-cooled fast neutron reactor. Designed for flexibility and resilience, the FMR can be distributed and sited in remote or resource-constrained locations.

The FMR plant is scalable and deployable in configurations of four modules (176 MWe), or six modules (264 MWe), tailored to meet regional or centralized power demands. It delivers reliable baseload power, while supporting dynamic grid requirements.

FMR Advantages

• High Efficiency: Achieves 42% net thermal-to-electric conversion efficiency, compared to ~33% in conventional reactors
Proven Fuel: Uses conventional uranium dioxide (UO₂), the same fuel type used in most light water reactors (LWRs) today
Fast Load-Following Capability: Rapidly adjusts output to integrate seamlessly with other renewables
Helium Coolant: Ensures safe, efficient heat transfer by use of a non-radioactive, non-corrosive, non-toxic, and optically transparent coolant
Advanced Materials: Maintains high power conversion efficiency and efficient fuel performance with use of SiGA® silicon carbide cladding
Dry-Cooled Design: Requires no water for cooling, allowing siting in remote or arid locations
Extended Refueling Cycle: Reduces operational outages and lifecycle costs because of 15-year core life

The FMR Energy Reliability and Security Supports:

• Remote Communities: Provides dependable power to areas with limited or no grid infrastructure, such as rural Alaska, Puerto Rico, and remote desert regions
• Independent System Operators (ISOs): Offers distributed generation to help reduce grid congestion and prevent overloading
• Capacity Markets: Delivers 24/7 reliable baseload power to offset the retirement of conventional coal and nuclear plants
