LAWRENCE LIVERMORE NATIONAL LABORATORY Executive tUnder the direction of the Office of Civilian Radioactive Waste Management, the Department of Energy's (DOE) Nevada Nuclear Waste Storage Investigations (NNWSI) project is evaluating a candidate repository site at Yucca Mountain, Ne vada, for permanent disposal of high level nuclear waste. The Lawrence Livermore National Labora tory (LLNL), a participant in the NNWSI project, is developing waste package designs to meet NRC requirements. Included are designs for the refer ence waste form configurations of: (1) spent fuel (SF), which consists of both consolidated and un consolidated spent fuel rods from pressurizedwater-reactor (PWR) and boiling-water-reactor (BWR) assemblies, (2) commercial high level waste (CHLW), as a borosilicate glass containing commercial spent fuel reprocessing wastes, and (3) West Valley/defense high level waste (WV/ DHIW) immobilized in borosilicate glass. Refer ence and alternative package designs have been developed for each waste form for both vertical and horizontal emplacement configurations. All designs are for emplacement in a tuff repository located above the water table (in the vadose zone).Conceptual designs and analyses for waste packages in tuff below the water table were devel oped for the Office of Nuclear Waste Isolation Summary (ONWI) by Westinghouse Electric Corporation in 1981 -82 (Westinghouse, 1983. The candidate hori zon was changed by NNWSI to the vadose zone in late 1982 (Vieth, 1982;Dudley and Erdal, 1982). LLNL has made changes in and additions to the conceptual designs to reflect this change in the re pository location. Analyses have been performed to determine conformance of the selected design ensemble to NRC design requirements in the cur rently understood repository environment. Fig ure 1 shows the reference conceptual designs. The selected designs (Gregg and O'Neal, 1983) include reference and alternative designs that vary in com plexity, performance, and cost.From this ensemble, one set of designs (for SF, CHLW, and WV/DHIW) will be chosen which is expected to meet Nuclear Regulatory Commission (NRC)/Environmental Protection Agency (EPA) requirements when analyzed with accura...

UCRL-LR-134107The Scrounge-atron AbstractThe Scrounge-atron is a concept that could provide a demonstration accelerator for proton radiography. As discussed here, the Scrounge-atron would be capable of providing a 20 GeV beam of ten pulses, 10 11 protons each, spaced 250 ns apart. This beam could be delivered once every minute to a single-axis radiographic station centered at the BEEF facility of the Nevada Test Site. These parameters would be sufficient to demonstrate, in five years, the capabilities of a proton-based Advanced Hydrotest Facility, and could return valuable information to the stockpile program, information that could not be obtained in any other way. The Scrounge-atron could be built in two to three years for $50-100 million. To meet this schedule and cost, the Scrounge-atron would rely heavily on the availability of components from the decommissioned Fermilab Main Ring.
