Omega has supported all aspects of commissioning, including planning & scheduling, design team support, transition to operations, work package closure, commissioning authority and quality assurance.
Omega’s Design Engineers, ANSI N42.6 Level II/III Test Engineers and support personnel have assisted with design, construction management, start-up testing, commissioning and operational readiness for the following projects:
Uranium Purification Facility (UPF)
Currently in design at the Y-12 National Security Complex, the UPF will be a state-of-the-art, consolidated facility for enriched uranium operations including assembly, disassembly, dismantlement, quality evaluation, and product certification.
Highly Enriched Uranium Materials Facility (HEUMF)
The HEUMF at the Y-12 National Security Complex is our nation’s central repository for highly enriched uranium, a vital national security asset. HEUMF’s design is consistent with the latest graded security protection guidance. The facility is constructed of reinforced concrete floors, walls, and roof; it sits on a 30-ft-thick mass concrete fill attached directly to bedrock. Advanced exterior and interior safeguards and security systems further ensure protection of the uranium materials inside HEUMF. Security doors are the latest in door system technology and meet all applicable protection requirements.
Oxide Conversion Facility (OCF)
Oxide conversion is an essential part of processes used to recycle highly enriched uranium and get it ready for return to use in nuclear warheads or put on the shelf for other projects. The OCF at the Y-12 National Security Complex converts uranium from an oxide form to uranium tetrafluoride (known as “green salt”), which then goes through a reduction process to form a purified uranium metal.
Prototype Purification Facility (PPtF)
The PPtF provides a purification process for manufacturing non-nuclear special materials needed to support the Stockpile Life Extension Program. Operations performed within the PPtF include: 1) dissolution, filtration, and recrystallization; 2) powder processing in a nitrogen atmosphere, and 3) drying, machining and inspection. The purification process will use flammable liquid acetonitrile (ACN) and will require special design features, including an adjoining tank farm to store ACN.
Spallation Neutron Source (SNS)
SNS is a one-of-a-kind research facility at the Oak Ridge National Laboratory that provides the most intense pulsed neutron beams in the world for scientific research and industrial development. SNS produces neutrons with an accelerator-based system that delivers short (microsecond) proton pulses to a target/moderator system, where neutrons are produced by a process called spallation. State-of-the-art experiment stations provide a variety of capabilities for researchers across a broad range of disciplines, such as physics, chemistry, materials science, and biology.
US ITER is an unprecedented international collaboration of scientists and engineers working to design, construct, and assemble a burning plasma experiment that can demonstrate the scientific and technological feasibility of fusion power for the commercial power grid.
Underground Test Facility
The U1a Complex is an underground laboratory at the Nevada National Security Site used for dynamic experiments with special nuclear material (SNM) and other weapon materials. The Complex provides an infrastructure of high-bandwidth diagnostics, data acquisition, timing and firing, control and monitor systems capable of supporting experiments designed to acquire information on fundamental materials properties, focused information to address specific weapon issues, and integral performance of weapon-like systems in a scaled geometry. U1a provides the unique capability of being the only facility authorized to conduct experiments with high explosives mated to weapon relevant quantities of Plutonium that are expended and later safely entombed in the underground environment.
Device Assembly Facility (DAF)
The DAF was designed and built to consolidate all nuclear explosive assembly functions, to provide safe structures for high explosive and nuclear explosive assembly operations, and to provide a state-of-the-art safeguards and security environment. The DAF is a collection of more than 30 individual steel-reinforced concrete buildings connected by a rectangular common corridor. The entire complex, covered by compacted earth, spans an area of 100,000 square feet.
Criticality Experiment Facility (CEF)
The operations of the CEF enable DOE personnel to gain knowledge and expertise in advanced nuclear technologies that support the following areas: Nuclear materials management and criticality safety; Emergency response in support of counter-terrorism activities; Nuclear Nonproliferation in support of domestic and international programs to control excess nuclear materials; Criticality experiments in support of Stockpile Stewardship and other programs; Training activities to develop and maintain capabilities and expertise within the national nuclear materials handling community.
Plutonium Stabilization and Packaging System (PuSPS)
The PuSPS processes feed material in two phases: stabilization and packaging. The stabilization phase includes calcination of the material in a furnace to remove water and organics. After stabilization, the material is automatically transferred to the tipping/dispensing/fill area that begins the packaging phase. The material is poured into the material container which is then put inside the inner can. The inner can resides outside of the glove box but is connected by a sphincter seal that allows the material container to be inserted while maintaining a contamination free exterior. The inner can is laser welded closed and placed into the final outer container which is also laser welded.
Isotope Fuels Impact Tester (IFIT)
The IFIT provides a method to impact 238-plutonium heat sources and sub-assemblies of radioisotope heat generators to determine the impact response and the effect of different target materials. The 7-inch bore diameter launcher utilizes compressed gas in the breech to propel a projectile at velocities up to 150 m/s. In early 2009, DOE NE-34 requested several impact tests using the IFIT to qualify the impact properties of a new generation of radioisotope power systems for space missions. The IFIT restart team has accomplished the daunting task of the restart of the IFIT to normal operating conditions after a period of approximately seven years of no activity.
Consolidated Incinerator Facility (CIF)
The CIF at the Savannah River Site (SRS) is a rotary kiln incinerator with a secondary combustion chamber and is designed to treat low-level radioactive, hazardous, and mixed wastes in both solid and liquid forms. Feed materials for the CIF include contaminated gloves and coveralls, spent solvent from the canyon facilities, and benzene from the Defense Waste Processing Facility (DWPF).
Defense Waste Processing Facility (DWPF)
The DWPF converts the liquid nuclear waste currently stored at the Savannah River Site (SRS) into a solid glass form suitable for long-term storage and disposal. DWPF vitrifyies sludge from the liquid nuclear waste currently in tank storage along with the cesium and strontium from the salt forms in the waste. A sand-like borosilicate glass (called “frit”) is mixed with the waste and sent to the plant’s 65-ton steel and ceramic melter. In the melter, electricity is used to heat the waste/frit mixture to nearly 2,100 degrees Fahrenheit until molten. This molten glass-waste mixture is poured, in a pencil-thin stream, into stainless steel canisters to cool and harden.
Integrated Waste Treatment Unit (IWTU)
The IWTU, a first-of-a-kind, 53,000-square-foot facility, will begin in 2014 treating 900,000 gallons of liquid radioactive and hazardous waste that has been stored in underground storage tanks – above the Snake River Plain Aquifer – for decades. iwtu, located east of the Idaho Nuclear Technology and Engineering Center, will use a steam-reforming technology to heat up the liquid waste, essentially drying it; consolidating the solid, granular material; packaging it in stainless steel canisters; and storing the containers in concrete vaults at the site. Ultimately, the treated material will be transported to a national geologic repository for permanent disposal.
