Radiological and Health Physics Analysis Support

The contract seeks technical support for radiological and health physics analysis with a focus on source term characterization, environmental dispersion modeling, and validation of radiological dose assessments. This subcontract is issued under the NAICS code 541620 for scientific and technical consulting services and is designated as an SBA set-aside, indicating it is reserved for small business concerns. The work is intended to support the U.S. Nuclear Regulatory Commission’s headquarters in enhancing the accuracy and reliability of radiological consequence analyses, particularly in scenarios involving potential environmental releases. Performance of the required tasks will be conducted without a specified physical location, allowing flexibility for the contractor to carry out the work remotely or as needed to meet deliverables. The solicitation was posted on June 30, 2026, with a response deadline of August 14, 2026, providing interested parties approximately six weeks to submit proposals. The nature of the support is analytical and technical, requiring expertise in nuclear science, environmental modeling, and dose assessment methodologies. The contractor will be expected to deliver validated models and analyses that contribute to the NRC's regulatory and safety evaluation capabilities. While no point of contact or physical place of performance is listed, the contract is tied directly to federal radiological safety oversight activities and must comply with all applicable NRC standards and procedures.
