Notice of Intent to Sole Source Cesium-137 with Installation and Irradiator Calibration

The Uniformed Services University of the Health Sciences intends to award a sole-source, firm-fixed-price commercial contract for a Cesium-137 source of approximately 1000 Ci (37 TBq), including its installation and calibration of the existing Hopewell GC-60 irradiator located in Bethesda, Maryland. This procurement is governed by strict regulatory requirements under the Nuclear Regulatory Commission, specifically NRC Material License 19-08330-02, Item 21, which mandates that all repair and installation activities must be performed exclusively by entities holding an NRC license. The procurement is being conducted under a Notice of Intent to Sole Source, posted on May 22, 2026, with responses due by June 6, 2026. Although the contract is proposed as sole-source, responsible sources are invited to submit capability statements, proposals, or quotations to demonstrate clear and convincing evidence that competition would be advantageous to the government, and that it would not be cost or time prohibitive. The NAICS code for this action is 334517, and the procuring agency is the Department of Defense through USUHS, with all performance required in Bethesda, Maryland. The government will not assume liability for any costs incurred by respondents, and no contract value has been disclosed as the notice is pre-solicitation. No formal contract clauses, evaluation factors, delivery schedules, or inspection criteria have been detailed, as this document serves solely to inform potential vendors and evaluate competitive feasibility.
