Powering Progress. Closing the Fuel Cycle.

The Energy Multiplier Module (EM²) is a next-generation, 265-megawatt electric (MWe) gas-cooled small modular reactor. Its fast neutron spectrum enables closure of the fuel cycle and transmutation of high-level waste. This patented design first established the key technologies now used in the company’s Fast Modular Reactor (FMR) and is configured to deliver significantly higher power output per module to efficiently meet baseload energy needs.

With over 60 years of safe reactor research and development experience, General Atomics has incorporated advanced technologies and engineering innovations into EM² to meet the three core objectives required of advanced reactors: significantly enhanced safety, efficient use of energy resources with reduced waste, and low-cost, clean electricity.

EM² is optimized to meet the higher, base-load power demands, configured in 1 to 4 units per plant, to replace fossil-fired and conventional nuclear plants well in the 2030s and beyond.

The company's ongoing work on EM² has been the subject of scientific papers and presentations. A current list of these can be found here.
