SANTA FE PROJECT

CESIUM SOURCE HIGH RANGE WELL REMOVAL

Project Description

USA Environment, LP was awarded the contract to remove a breeched cesium-137 source and corresponding High Range Well (HRW). The worked was performed in a constricted environment that required extreme detail and precision. The project included the removal of the well concrete pedestal, excavating surrounding soil to a depth of approximately eight feet below ground surface and removal of the breeched casing and cesium source. Due to the condition of the HRW, potential for soil contamination and its resistance for vertical removal, extreme care was taken to avoid further damage to the casing, thereby releasing the cesium source. Soil contamination levels were continuously monitored during excavation utilizing a Canberra Inspector 1000. A floor was fabricated after excavation for shielding purposes that surrounded the HRW during the well and source extrication. Once the HRW was removed, it was cut for placement in a 2R disposal container for shipment and disposal.

Project Highlights

  • USA returned to the site at a later date and performed the final soil removal and remediation of the well location in order for the owner to terminate the license and decommission the site. An additional 30 drums of Cs-137 impacted soil were removed and profiled for disposal.
