IN-CORE SYSTEMS

Mirion Technologies Sensing Systems Division offers a variety of in-core sensors, including fixed and movable detectors, self-powered detectors and local power range monitors for all types of nuclear reactors. In addition we also supply radiation-resistant cables and a wide range of accessories.

Nuclear facilities around the world specify our In-Core Sensors for safety and reliability. All of the Sensing Systems Division In-Core Sensors are constructed of inorganic materials throughout to withstand the extreme environments of the power reactor core. Typical construction materials for the sensor and integral cable include stainless or inconel metallic sheaths with alumina or magnesia insulation.

All self-powered detectors employ the most durable single-sheath construction design. Other in-core detector types by the Sensing Systems Division are joined using the latest laser beam welding and brazing technology. Critical welds and brazes are non-destructively tested with state-of-the-art equipment. All fixed and movable detectors are calibrated for radiation sensitivity to ensure that they meet or exceed acceptance criteria demanded by our customers.

Our in-house, quality assurance and control program is a continuous, all-encompassing effort. From a computerized tracking system rating our materials' vendors, to our rigorous inspection and testing procedures, insures that adherence to our total quality system is well-documented.

The Sensing Systems Division supplies a full-line of In-Core Systems, including:

  • In-Core Sensors
  • Cabling
