This work examines the effect of recycling Ln(III) fission products together with An(III) TRU in existing PWRs without separating them as commonly assumed. TRU recycling in three different fuel forms was studied: U-MOX, Th-MOX, and Fertile Free Fuel. We analyzed the effect of Ln(III) separation on fuel cycle length, efficiency of TRU destruction, and the core reactivity feedback coefficients. T...

The ability of Pelobacter carbinolicus to oxidize electron donors with electron transfer to the anodes of microbial fuel cells was evaluated because microorganisms closely related to Pelobacter species are generally abundant on the anodes of microbial fuel cells harvesting electricity from aquatic sediments. P. carbinolicus could not produce current in a microbial fuel cell with electron donors...

Knowledge of forest fuels and their potential fire behavior across a landscape is essential in fire management. Four customized fire behavior fuel models that differed significantly in fuels characteristics and environmental conditions were identified using hierarchical cluster analysis based on fuels data collected across a boreal forest landscape in northeastern China. Fuel model I represente...

Factors contributing to the proliferation resistance of CANDU reactors are examined, from the point of view of both intrinsic design features (related primarily to fuel cycle details and operational requirements), and extrinsic measures (primarily IAEA safeguards). It is shown how the technical features of CANDU reactors and fuel cycle, in most cases derived from the fundamental physics of heav...

We demonstrate an oxide-stabilized III–V photoelectrode architecture for solar fuel production from water in neutral pH. For this tunable architecture we demonstrate 100% Faradaic efficiency for hydrogen evolution, and incident photon-to-current efficiencies (IPCE) exceeding 50%. High IPCE for hydrogen evolution is a consequence of the low-loss interface achieved via epitaxial growth of a thin ...
