The U.S. Department of Agriculture seeks a sole-source contractor to perform a turnkey reload of approximately 20,000 curies of cobalt-60 in a Foss Therapy Model 484F-C cobalt-60 irradiator.

The scope also includes preventive maintenance and testing of the irradiator's mechanical, electrical, interlock, and safety systems; incidental repairs; written reporting; and refresher training for USDA personnel. Performance is scheduled between November 2026 and February 2027, with the work plan due within three weeks after award and RSO concurrence required before work begins. The notice is a sole-source presolicitation, although responsible sources may submit capability statements for consideration of a competitive procurement.
