In-core detectors used in the instrumentation channels of nuclear power plants
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
Electronics
Out-of-core radiation sensors for all types of reactors
OUT-OF-CORE SYSTEMS
The Sensing Systems Division supplies a full line of out-of-core radiation sensors for all types of reactors. Sensors include proportional counters, compensated and uncompensated ionization chambers, power range assemblies, fission counters and chambers along with cables, connectors and assemblies.
Sensing Systems Out-of-Core Sensors have a worldwide reputation for outstanding reliability, accuracy and durability.
To withstand the extreme radiation and temperature environments encountered in a nuclear power plant, Out-of-Core Sensors are constructed entirely of inorganic materials. Whenever possible, materials are selected to minimize activation and, thus, to facilitate handling of radioactive sensors.
Out-of-Core Sensors by are produced in a carefully controlled manufacturing facility. Each sensor is followed through its assembly process step by step to verify that production and design specifications are being met. All welds are non-destructively tested, and the specified limits of each sensor's radiation sensitivity are verified by our calibrated neutron and gamma testing facilities.
Detectors to provide full reactor Neutron and Gamma flux measurements
A full range of safety related signal processing and cabling components that interface with our In-core and Ex-core detectors to provide full reactor Neutron and Gamma flux measurements.
Instrumentation systems include Incore flux and Temperature measurements, Excore start up, Intermediate, Power and wide range measurements, Boron concentration (Boron meter) measurements.
Systems include Detectors, In-containment cables, In-containment preamplifiers, Penetration modules , signal amplifiers and interface to safety shutdown systems.
Nuclear containment penetration equipment
Canister and Modular designs are available with a variety of electrical and fiber optic feedthroughs. All electrical feedthroughs contain solid copper conductors in a swaged construction. Designed for 60 year, normal service temperature of 150 °F (65 °C) – higher temperatures can be accommodated with an adjustment in ampacity. All EPA are qualified to plant-specific temperature, pressure and chemical spray, with the requirements of IEEE-317, for 60 year service life. All EPA are ASME Boiler and Vessel Code (NPT Stamp) for manufacture to Section III, Subsection NE, Class MC and are qualified by test to the current standards of IEEE-317, IEEE-323, IEEE-344 and IEC Publication 772. All parts are manufactured to ANSI/ASME NQA-1 and 10 CFR 50 Appendix B.
EPA design with epoxy seal is also available.
