Notice of Intent to Sole Source Commercial Supply Contract Type: Firm Fixed Price Title: Portable Tritium Air Monitor Notice ID Number: NB610010-26-02238

PURPOSE

This is a notice of intent the Acquisition Management Division (AMD) at the National Institute of Standards and Technology Material Measurements Lab, Center for Neutron Research (NCNR) intends to procure a quantity of two (2) tritium air monitors on a sole source basis with Mirion Technologies using FAR Part 12.102-1(a), Restricting Competition.

This notice shall not be construed as a Request for Quote. Respondents are advised that the U.S. Government will not pay for information or administrative costs incurred in the response to this notice. All costs associated with responding to the notice will be solely at the interested party’s expense. Not responding to this notice does not preclude participation in any future RFQ or other solicitation (if any are issued). This is a notice of intent to sole source, not a pre-solicitation notice. There is no formal solicitation available at this time. No award will be made as a result of this notice. Respondents will not be notified of the results of this notice, or results of information submitted.

BACKGROUND

NCNR Technical Specifications require that tritium concentrations be maintained within established limits and that releases be kept As Low As Is Practicable (ALAP). While fixed building and stack monitoring systems provide continuous effluent surveillance, the SAR requires enhanced monitoring during non-routine operations and activities with the potential to increase tritium releases. To support implementation of the radiation safety program, portable tritium monitors are required to enable monitoring in areas where airborne tritium may be present. Particularly during activities with the potential for release. The monitors shall provide continuous data logging, audible and visual alarms, and be easily portable to support flexible deployment.

The portable tritium monitor will supplement installed systems by enabling localized, real-time assessment in areas not continuously monitored, including during maintenance, system evolutions, and leak investigations. This capability supports early detection of tritium migration, timely corrective actions, and verification of containment integrity. It will also be used to corroborate fixed monitor performance and grab sample analyses, ensuring reliable and defensible monitoring data.

SCOPE

The Contractor shall deliver a quantity of two (2) Portable tritium monitor with manual compensation 600 cc ionization chamber inclusive of the following:

1. External alarm beacon Quantity four (4)

2. Transport case, Quantity two (2)
