The issue of waste management has been studied simultaneously along with the development of the ARIES heavy ion driven inertial fusion energy (IFE) concept. Options for waste management include disposal in repositories, recycling, or clearance from regulatory control, following a reasonable cooling period. Here, we are concerned with the feasibility of(More)
Wilson, P.: On inferring hybridity from morphological intermediacy. The type of intermediacy that separates hybridity from divergence is not multivariate intermediacy; it is the coincidence of intermediate character states. For the purpose of showing hybridity, analyses should distinguish between the two types of intermediacy. (1) Hybrid indices fail to do(More)

• In most cases, candidate liquids generate multi-thousand tonnes of high-level waste. • Tangential injection scheme results in highest WDR. • Pb and LiPb are more radioactive than Sn and Flibe. • Online removal of transmutation products could allow tonnes of liquid materials to be disposed as low-level waste or preferably, released for use in similar(More)
As nuclear power expands, technical, economic, political, and environmental analyses of nuclear fuel cycles by simulators increase in importance. To date, however, current tools are often fleet-based rather than discrete and restrictively licensed rather than open source. Each of these choices presents a challenge to modeling fidelity, generality,(More)
Solid modeling engines are capable of faceting CAD models but may facet each face independent of adjacent faces. Regions of the resulting model have gaps between faces of their boundaries. An algorithm is described to seal faceted CAD models such that the boundary of neighboring faces has the same discretization along their shared edges. The algorithm works(More)
Introduction Module 7 location with vertical gaps Summary of Module 7 Vacuum Vessel Results • A stepped gap reduces local peaking but not the relative average parameters • Doubling the width of a straight gap or stepped gap with small offset doubles VV peak parameters • For a stepped gap with large offset, doubling gap width increases VV peak parameters(More)
