Description

The Los Alamos Large Scale Demonstration and Deployment Project (LSDDP) in support of the US Department of Energy (DOE) Deactivation and Decommissioning Focus Area (DDFA) is identifying and demonstrating technologies to reduce the cost and risk of management of transuranic element contaminated large metal objects, i.e. gloveboxes. DOE must dispose of hundreds of gloveboxes from Rocky Flats, Los Alamos and other DOE sites. Current practices for removal, decontamination and size reduction of large metal objects translates to a DOE system-wide cost in excess of $800 million, without disposal costs. In FY99 and FY00 the Los Alamos LSDDP performed several demonstrations ... continued below

Description

The Los Alamos Large Scale Demonstration and Deployment Project (LSDDP) in support of the US Department of Energy (DOE) Deactivation and Decommissioning Focus Area (DDFA) is identifying and demonstrating technologies to reduce the cost and risk of management of transuranic element contaminated large metal objects, i.e. gloveboxes. DOE must dispose of hundreds of gloveboxes from Rocky Flats, Los Alamos and other DOE sites. Current practices for removal, decontamination and size reduction of large metal objects translates to a DOE system-wide cost in excess of $800 million, without disposal costs. In FY99 and FY00 the Los Alamos LSDDP performed several demonstrations on cost/risk savings technologies. Commercial air pallets were demonstrated for movement and positioning of the oversized crates in neutron counting equipment. The air pallets are able to cost effectively address the complete waste management inventory, whereas the baseline wheeled carts could address only 25% of the inventory with higher manpower costs. A gamma interrogation radiography technology was demonstrated to support characterization of the crates. The technology was developed for radiography of trucks for identification of contraband. The radiographs were extremely useful in guiding the selection and method for opening very large crated metal objects. The cost of the radiography was small and the operating benefit is high. Another demonstration compared a Blade Cutting Plunger and reciprocating saw for removal of glovebox legs and appurtenances. The cost comparison showed that the Blade Cutting Plunger costs were comparable, and a significant safety advantage was reported. A second radiography demonstration was conducted evaluation of a technology based on WIPP-type x-ray characterization of large boxes. This technology provides considerable detail of the contents of the crates. The technology identified details as small as the fasteners in the crates, an unpunctured aerosol can, and a vessel containing liquids. The cost of this technology is higher than the gamma interrogation technique, but the detail provided is much greater.
