About this IDV
The U.S. Geological Survey Office of Acquisitions and Grants awarded an indefinite-delivery contract to Oregon State University for neutron irradiation geochronology services, with a ceiling of $300,000.00 and an award date of July 20, 2026. This is a single-award contract with a performance completion date of July 20, 2031.
The originating solicitation was a Total Small Business set-aside issued under NAICS 541380 (Testing Laboratories and Services), though the award to Oregon State University—a state-controlled institution and not a small business—indicates the procurement structure shifted or the set-aside classification was superseded prior to award. The pre-solicitation Sources Sought Notice, posted February 9, 2026, sought contractors capable of irradiating mineral and rock samples in a nuclear reactor to convert stable potassium-39 to radioactive argon-39 for 40Ar/39Ar geochronology work. The requested capability included placement of samples within a cadmium liner in the reactor core to minimize neutron flux gradients, with the reactor required to have published neutron interference correction values in scientific literature for seven specified isotopic ratios. Acceptance was to be measured by noble gas mass spectrometer measurements confirming sufficient 39Ar production for precise geochronology on standards including Bodie Hills, Taylor Creek, Fish Canyon sanidine, and GA1550 biotite. The contract serves geochronology laboratories located in Denver, Moffett, and Reston.
