Quick Summary
The U.S. Geological Survey (USGS) is conducting market research through a Sources Sought notice to identify qualified Total Small Business firms capable of providing Neutron Irradiation Geochronology services. This effort aims to support USGS 40Ar/39Ar geochronology laboratories and is intended to lead to an Indefinite Delivery Indefinite Quantity (IDIQ) contract. Responses are due by February 16, 2026.
Purpose & Scope
This notice serves solely for market research and acquisition planning. The USGS requires neutron irradiation of mineral and rock samples in a nuclear reactor to convert stable 39K to radioactive 39Ar, essential for potassium content assessment in 40Ar/39Ar geochronology. These services are critical for research in economic and regional geology, geologic mapping, and natural hazard assessments.
Key Requirements
Contractors must demonstrate:
- Experience in irradiating samples for 40Ar/39Ar geochronology.
- Capability to irradiate samples in a cadmium liner within the reactor core.
- Access to a reactor with published neutron interference correction values.
- Ability to return irradiated samples in sealed quartz glass ampules, accompanied by appropriate radioactive materials and irradiation parameter documentation, with ampules clearly labeled.
- Performance standards require noble gas mass spectrometer measurements to show sufficient 39Ar production for precise, accurate geochronology on laboratory standards.
Contract Details
- Contract Type: Indefinite Delivery Indefinite Quantity (IDIQ)
- Period of Performance: Base year plus four option years (ordering period dates adjustable)
- Place of Performance: The nuclear reactor facility of the selected contractor.
- Set-Aside: Total Small Business Set-Aside (FAR 19.5)
Submission Requirements
Interested Total Small Business firms should submit a capability statement, limited to five (5) pages. The statement should include:
- Company details, Point of Contact (POC), Unique Entity Identifier (UEI), SAM status, business size, and socioeconomic status.
- A description of capabilities, experience, and facility availability relevant to the required neutron irradiation services. Submissions must be sent electronically via email to Joel Berberena at jberberena@usgs.gov.
Important Notes
This is a market research notice only and does not constitute a solicitation or commitment to award a contract. The Government will not reimburse respondents for costs incurred. Timing is critical due to the short half-lives of isotopes and the need for timely analysis.
