FY00 RESULTS FOR THE LOS ALAMOS LARGE SCALE DEMONSTRATIONAND DEPLOYMENT PROJECT (LANL RELEASE NO: LA-UR/LA-CP 00-5558)

摘要

Los Alamos Large Scale Demonstration and Deployment Project (LSDDP) in support ofrnthe United States Department of Energy (DOE) Deactivation and DecommissioningrnFocus Area (DDFA) is identifying and demonstrating technologies to reduce the cost andrnrisk of management of transuranic element contaminated large metal objects, i.e.rngloveboxes. DOE must dispose of hundreds of gloveboxes from Rocky Flats, LosrnAlamos and other DOE sites. Current practices for removal, decontamination and sizernreduction of large metal objects translates to a DOE system-wide cost in excess of $800rnmillion, without disposal costs.rnIn FY99 and FY00 the Los Alamos LSDDP performed several demonstrations onrncost/risk savings technologies. Commercial air pallets were demonstrated for movementrnand positioning of oversized crates in neutron counting equipment. Air pallets are able tornreduce annual operating costs by $200,000 and address the complete waste managementrninventory, whereas the baseline wheeled carts could address only 25% of the inventory.rnA gamma interrogation radiography technology was demonstrated to supportrncharacterization of the crates. The radiographs were extremely useful in guidingrnselection of crates for opening and the best locations for opening very large crated metalrnobjects. The cost of radiography was $400 to $630 per crate, but the operating benefit isrnhigh. A second radiography demonstration evaluated a technology based on WIPP-typernx-ray characterization of drums. This technology identified details as small as fastenersrnin the crates, an unpunctured aerosol can, and a vessel containing liquids. The cost ofrnthis technology is approximately $1100 per crate, but it provides greater detail than therngamma interrogation system.rnAnother demonstration compared a Blade Cutting Plunger and reciprocating saw forrnremoval of glovebox legs and appurtenances. The Blade Cutting Plunger costs wererncomparable to the baseline, and a significant safety advantage was reported. Late inrnFY00 a demonstratio n was conducted to evaluate a security camera as an option forrndocumentation of the contents of waste packages. Qualitatively, the NTVision systemrnshowed potential for reduced record keeping and improved data quality control.
