RFI: Area Radiation Monitor Procurement for APS

Argonne National Laboratory (ANL) is issuing a Request for Information (RFI) for vendors to provide a complete Area Radiation Monitor (ARM) system solution for its Advanced Photon Source (APS) facility. The RFI seeks information on the design, manufacturing, and long-term support for approximately 50 replacement ARMs, which are critical safety components. Key requirements include detection of neutron and photon radiation within specific energy ranges, capability to detect pulsed radiation, compact mechanical and electrical specifications, NEMA 12 / IP54 rated enclosure, Ethernet communication with EPICS driver support, local displays, and visual/audible alarms. ANL is also requesting information on vendor technical capabilities, support models (warranty, calibration, updates, on-site support), repair turnaround, recommended spares, project timelines for delivery of initial and subsequent units, production capacity, and a proposed delivery schedule. Budgetary estimates are requested for per-unit cost, non-recurring engineering, annual support/maintenance, training, shipping, and commissioning. The anticipated procurement schedule includes an RFP issuance in Q2 2026 and a contract award in FY27.

The APS U Radiation Monitor Specifications document outlines the detailed requirements for a radiation monitoring system capable of detecting neutrons and photons. Key mechanical specifications include a compact, NEMA 12 or better enclosure with physical security features like a built-in key lock, and a total weight under 100 pounds. Electrical requirements specify 120 VAC or DC input, UL listing, and safety guarding for voltages above 50 volts. Detection capabilities must cover thermal to 1 GeV for neutrons and 100 keV to 100 MeV for photons, with dose ranges from 0.1 to 1000 mrem/h for both. The system requires two rate meter channels, integrated dose measurement, and

Addendum No. 001 to Request for Information (RFI) No. 6-S176-I--05497-00, issued by the U.S. Department of Energy laboratory managed by UChicago Argonne, LLC (Argonne National Laboratory), addresses several questions from offerors. The RFI concerns the replacement of aged-out units and requires seamless integration into the current system, specifically regarding communication and alarm relay protocols. It clarifies that the existing network will be used for alarm status communication. The addendum also specifies detection capabilities, requiring an energy range for neutrons from thermal to 100 MeV and for photons from 100 keV to 10 MeV, focusing on accelerator-produced radiation rather than specific radionuclides. Finally, it details the electrical equipment inspection procedure, which involves checking connections, grounding, and general compliance with the NEC (National Electrical Code) – NFPA 70, 2017 ed., without a specific testing procedure.
