Development of Accident Tolerant Instruments for Nuclear Safety

This research article discusses the design and implementation of new accident-tolerant sensors developed by Mitsubishi Heavy Industries to enhance measurement reliability during severe nuclear accidents. The sensors are engineered to withstand extreme environmental conditions, including high temperatures, pressures, and radiation exposure, based on lessons learned from the Fukushima Daiichi Accident. The paper details the specifications, testing results, and current operational status of these s
