Case Study: Idaho National Laboratory achieves safer, more efficient nuclear pump monitoring with Benchmark Electronics' custom multi-sensor solution

Idaho National Laboratory reduces manual RHR pump surveillance with Benchmark Electronics and 2-year wireless sensing

Idaho National Laboratory, a leading center for nuclear energy research, faced a significant challenge in monitoring its residual heat removal pumps. The conventional process was a labor-intensive manual activity requiring technicians to take measurements in hard-to-access, high-radiation areas. They needed an automated, secure solution that could monitor this standby equipment. Idaho National Laboratory partnered with Benchmark Electronics and KnowledgeRelay to develop a custom Multi-Sensor Monitoring Unit (MSMU).

Benchmark Electronics designed a custom MSMU that uses vibration, acoustic, and temperature sensors to monitor the pumps. The solution features secure ultra-wideband communication to avoid interference and a standby feature that powers the unit only when the pump runs. This automated system successfully eliminated the need for dangerous manual inspections, improving safety and creating a more cost-effective work environment. The project was deemed a success as the MSMU met all six of the laboratory's initial requirements.
