On-the-fly nuclear data processing methods for Monte Carlo simulations of intermediate and fast spectrum systems
… transport simulations of intermediate and fast spectrum systems are developed and implemented in a continuous-energy Monte Carlo code. First, a capability to compute temperature-dependent unresolved resonance region (URR) cross sections directly from zero-temperature average resonance …

Feasibility Study of Minor Actinide Transmutation In Light-Water Reactors With Various Am/Cm Separation Efficiencies
… fission to capture cross section ratio in a fast neutron spectrum, the transmutation of MA is most effective in fast spectrum systems. However, MA transmutation can be carried out, albeit less effectively, in a thermal spectrum. This work examines MA transmutation in a thermal spectrum …

Impact of alternative nuclear fuel cycle options on infrastructure and fuel requirements, actinide and waste inventories, and economics
… single-pass plutonium recycling in thermal spectrum LWRs using Mixed OXide (MOX) fuel; 2) Multi-recycling of TRU in sodium-cooled fast spectrum burner cores, characterized by a fissile conversion ratio lower than 1 (FBu); 3) Multi-recycling of TRU in sodium-cooled fast breeders with a …

A variable threshold for an energy detector using GNU radio
Spectrum is a natural resource and should be treated as such. Spectrum has dual use applications that range from short distance communication links such as Bluetooth to health, power systems, transport, smart city applications and space communications and exploration. Next Generation Networks …

MULTI-PHYSICS DESIGN AND ANALYSES OF LONG LIFE REACTORS FOR LUNAR OUTPOSTS
… the operational life of this compact, fast spectrum reactor is increased by reconfiguring the core geometry to reduce neutron leakage and parasitic absorption, for the same amount of HEU in the core, and meeting launch safety requirements. The multi-physics analyses determine the …
