D & D - More Information
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.
