Essential to Safety: Imaging & Sensing Technology (IST)

Mirion was formed in 2005, unifying a set of nuclear operations under a single mission. One key player is IST — Imaging and Sensing Technology Corporation — a leading designer and assembler of equipment for nuclear power plants.

IST Logo Line

When the combination took place, IST was comprised of several product lines. The Industrial product lines were divested, and the following two nuclear product lines were retained:

  • Sensing Systems Group: a top producer of in-core and ex-core radiation detectors and electrical penetrations.
  • Imaging Systems Group: a global market leader in radiation tolerant and high temperature cameras for remote inspection.

IST France™ & IST Conax Nuclear™

Mirion's IST product lines of in-core and ex-core detectors, and electrical penetrations, including the IST France™ (the former nuclear division of Auxitrol) and IST Conax Nuclear™ lines, steadfastly serve crucial roles in ensuring safety and precision in nuclear power plants across the globe. They provide cutting-edge in-core and ex-core detectors and electrical penetration assemblies for nuclear reactor instrumentation and containment, as well as connectors and cables designed to withstand severe accident conditions.
