NFS Thorium/Uranium Facilities D&D
NFS has decommissioned its Thorium/Uranium-233, Enriched Uranium Oxide and Uranium/Thorium Metal Production Facilities. The projects involved the D&D of process systems, laboratories and scrap recovery operations at its Tennessee plantsite under NRC jurisdiction. The facilities involved more than 45,000 square feet of buildings and 100,000 cubic feet of uncompacted radioactively contaminated waste (gloveboxes, equipment, ventilation, piping, etc.). The projects were completed per applicable requirements of NRC Title 10, Parts 30 and 70 and 40 CFR Part 761. NFS provided all project management, planning, engineering, permitting/compliance, health & safety, waste management, analytical and NQA-1 implementations.

Argonne Building 212 Glovebox (Pu) D&D
NFS was awarded a contract for on-site D&D of 61 gloveboxes for Argonne National Laboratory East. The project presented a unique problem since, the lab containing the gloveboxes was surrounded by occupied offices. NFS developed: a site-specific health and safety plan; in-situ glovebox characterization utilizing transportable, active-passive, neutron-flux assaying chamber capable of measuring plutonium contamination to a level of < 10 nCi per gram; equipment removal and internal decontamination of the gloveboxes, size reduction and packaging of the gloveboxes to meet DOE Hanford and WIPP Waste Acceptance Criteria and removal of residual contamination from the remaining piping and room air filtration systems.

DOE Accelerated Site Technology Deployment (ASTD)
NFS' advancements in high risk D&D are playing an important role in reducing the cost of clean up at DOE site, nationwide. The company's innovative DVRS technologies are now fully deployed at Los Alamos National Laboratory(LANL). At LANL, the DVRS will be used to first process more than 5,000 cubic meters of oversized metallic plutonium-contaminated waste currently in storage. The DVRS will later be redeployed to other DOE sites with similar waste issues. Some government estimates have stated that by sharing the DVRS among DOE sites, taxpayers could save up to $167 million when compared to conventional methods for storing or disposing of wastes destined for processing within the DVRS.

NFS has provided a variety of technical services for other public and private facilities, including: DOE Hanford, DOE Rocky Flats, DOE Mound and DOE Oak Ridge along with various commercial fuel cycle facilities. The company's research and development work in D&D-related technologies have involved: waste management, decommissioning techniques, radiological processing and control programs, and related software systems development.
