Repair of Associated Particle Imaging Neutron Generator (Model DT108-API)

The United States Department of Agriculture Agricultural Research Service is issuing Request for Quotation (RFQ) 1232SAQ0023 for the repair of an Associated Particle Imaging Neutron Generator (Model DT108-API). The repair services involve replacing the API window, YAP scintillator, viewport, and scintillator holder due to a slow leak caused by a cracked weld, along with safe disposal of tritium-contaminated parts, potential foil replacement, helium leak checking, and functional testing to verify plasma and neutron generation. The contractor must provide calibration documentation and leak testing certifications per Nuclear Regulatory Commission guidelines, and must furnish a 3-month warranty on all provided parts. Quotations will be evaluated using a lowest price technically acceptable method, and vendors must submit detailed quotes including pricing, minimum specifications, authorized vendor verification, and key personnel resumes with active Unique Entity Identification (UEI) SAM registration. Questions must be submitted by December 23, 2025, at 5:00 PM Eastern Time, and quotations are due by January 5, 2026.

This procurement is designated as a Total Small Business Set-Aside under NAICS code 334516 (Analytical Laboratory Instrument Manufacturing) with a small business size standard of 1,000 employees. The justification documents indicate that Adelphi Technology Inc. possesses unique proprietary technologies, exclusive engineering drawings, firmware, and calibration algorithms necessary for this specialized repair, though the solicitation is technically open to all responsible small business sources. The required delivery date is March 25, 2026, to the Sea Soil Dynamics Research Unit in Auburn, Alabama. While no specific award value is disclosed in the solicitation documents, the repair scope and specialized nature of the work involving tritium-containing sealed tubes and radiation certification requirements indicate a moderately complex undertaking requiring vendor expertise in nuclear equipment remediation and NRC compliance.
