Barcode Automation (BCAuto) for Los Alamos Material Control and Accountability System

The plutonium facility is actively processing material on a daily basis at LANL (4000-5000 transactions/month): (1) Physical operations, material transformations, material mixing, splitting, etc.; and (2) Electronic manipulations resulting primarily from updated NDA measurements. Improvements in efficiency and effectiveness are essential due to impacts of recent Voluntary Separation Program and the need to meet mission requirements with fewer personnel. New storage requirements (DOE M 441.1-1, Nuclear Material Packaging Manual) to protect worker safety require tracking of material and its corresponding container over long periods of time. Material at Risk tracking is essential to protect public safety and to ensure continuous operations to meet national security mission needs.

US/UK Loan Account Project Status PMOD477

The viewgraphs describe the status of PMOD477 for LANL. The meeting will occur at DOE-HQ with NA-11 and Military Applications personnel in attendance. Serves to repatriate material with a balance to zero by December 2012. Phase 1 -- Establish formality of operations for War Reserve (WR): Complete surrogate taskings to A90 through a Materials Channel and perform US/UK lessons learned; Complete the US/UK agreed Quality Acceptance Plan, Materials Plan, Shipping procedure, and establish the formal UK/US point of contacts. Phase 2 -- Metal Manufacture (WR): Process material and store material as electrorefined metal (ER) rings, with initial assay and isotopic analysis, prior to manufacturing. Material is cast into accepted configuration and appropriate acceptance document for each aliquot will be generated. Phase 3 -- Intermediate Material Manufacture, Packaging and Shipping (WR): Continue processing of the material in accepted configuration with appropriate acceptance documentation for each aliquot. Provide an initial tasking of the material owed to UK including appropriate quality acceptance documentation. Phase 4 -- Complete Tasking (WR). Phase 5 -- Residue Processing (Non-WR): Complete processing of residue material and waste into accepted configuration with appropriate acceptance document for disposal.

Zero source insertion technique to account for undersampling in GPR imaging

A method and system for detecting the presence of subsurface objects within a medium is provided. In some embodiments, the imaging and detection system operates in a multistatic mode to collect radar return signals generated by an array of transceiver antenna pairs that is positioned across the surface and that travels down the surface. The imaging and detection system pre-processes the return signal to suppress certain undesirable effects. The imaging and detection system then generates synthetic aperture radar images from real aperture radar images generated from the pre-processed return signal. The imaging and detection system then post-processes the synthetic aperture radar images to improve detection of subsurface objects. The imaging and detection system identifies peaks in the energy levels of the post-processed image frame, which indicates the presence of a subsurface object.
