Westinghouse and Mirion Technologies Inc. are collaborating to supply advanced digital Excore Nuclear Instrumentation Systems (NIS), leveraging the state-of-the-art Mirion proTK™ product line to upgrade the aging NIS which exist today in operating nuclear power plants.
NIS, which measure neutron flux outside the reactor core, are among the most labor-intensive and costly systems to maintain in a nuclear power plant due to frequent calibration requirements and the reliance on outdated analog hardware-based technology. In fact, many operating reactors still use NIS equipment designed in the 1960s, leading to higher maintenance costs compared to modern digital software-based systems, like Mirion proTK™.
The new system will be installed in the same locations as the legacy systems, utilizing existing hardware and cabling. System indications will also be positioned in similar locations as the legacy system. This approach will support rapid and easy installation, as well as minimize disruptions to operations, procedures and training.
The proTK™ NIS drawers utilize modern manufacturing techniques with high-quality components and software-based signal processing to enhance reliability and performance. The digital proTK™ NIS drawers support long-term operation of the legacy fleet through lower operating costs and enhanced performance. The drop-in approach of the new drawers will enable legacy plant operators to leverage digital technology for their NIS with minimal impacts to the overall system and plant operations.
