Project Highlights: 

• Turnkey remediation of radiological-contaminated (highly enriched uranium) industrial site, residence and public street/utilities

• Partnered with client to plan and execute phased remediation on incrementally-funded project

• Secured regulatory approval for less restrictive DCGLs, accelerating schedule and reducing cost

• In situ screening during PDI and remediation enhanced accuracy of excavation design, expedited decision making, minimized waste T&D quantities and ensured compliance with disposal WAC

• Accomplished <1-day turnaround of characterization samples to quantify U-235 in all excavated soils and maintain nuclear criticality safety on-site

• Utilizing on-site laboratory and Nondestructive Assay (NDA) ensured Material Control and Accountability and compliance with disposal facility waste acceptance criteria, saving ~ $25,000 in additional off-site analytical costs for gamma spectroscopy on an expedited turnaround

• To ensure NRC license compliance, waste concentrations and container inventories were monitored/tracked to determine the ex situ SNM inventory above ground at any one-time and waste shipments were coordinated daily to remove SNM inventories expeditiously

• Project posed numerous complex issues, ranging from the presence of multiple buried utilities, asbestos-covered piping, and remediation work in public roadways and performing subfloor soil characterization/remediation inside existing buildings

• Brokered the waste shipment of 2,000 CY of highly enriched uranium contaminated soils and asbestos debris via intermodal containers on railcars
