Sample irratiation AR/AR geochronology

The US Geological Survey (USGS) Office of Acquisitions and Grants is seeking neutron irradiation services to support 40Ar/39Ar geochronology research across multiple USGS laboratories. The solicitation requires a contractor with a nuclear reactor capability to irradiate geological samples using a cadmium liner, with specific requirements including published neutron interference correction values. Vendors will be evaluated using a confidence rating system that assesses past performance, technical performance, and technical approach, with overall technical merit weighted more heavily than price. The Request for Quotation (RFQ) indicates that quotations must be submitted electronically via email by 2:30 p.m. Mountain Daylight Time on 04/16/2025. Evaluation will involve rating vendor capabilities as High, Some, or Low Confidence based on their understanding of requirements and proposed technical approach.

The solicitation has no specific set-aside designation and covers a base contract period from 04/21/2025 to 04/20/2026, with four potential option years extending through 04/20/2030. The contract includes multiple line items for different irradiation durations, with quantities ranging from 1 to 9 units per period and irradiation time increments spanning 4 to 100 hours. The procurement falls under NAICS category 541380 for Testing Laboratories and Services and PSC category B529 for Special Studies/Analysis-Scientific Data. While specific award values are not disclosed, the contract structure suggests a multi-year engagement for specialized scientific research services. The place of performance will be at the contractor's nuclear reactor facility, capable of meeting the precise scientific irradiation specifications outlined in the solicitation.
