"NASA/JSC intends to purchase research and development services from the Electric Power Research Institute (EPRI) for a continuation of an aneutronic fusion research project currently being conducted at the Johnson Space Center."

"The proposed design is based on neutron-free nuclear fusion as the primary energy source. An innovative beam conditioning/nozzle concept enables useful propulsive thrust directly from the fusion products, while some fraction of the energy is extracted via direct conversion into electricity for use in the reactor and spacecraft systems."
"Instead of using deuterium and tritium as the fuel stocks, the new motor extracts energy from boron fuel. Using boron, an "aneutronic" fuel, yields several advantages over conventional nuclear fusion."
