Advanced instrumentation for extreme environments

Oak Ridge National Laboratory (ORNL) is investigating embedded instrumentation and controls (I&C) technology for next generation nuclear power generation applications. Embedded systems encompass a wide range of configurations and technologies; we define embedding in this instance as the integration of the sensors and the control system design into the component design using a systems engineering process. Embedded I&C systems are often an essential part of developing new capabilities, improving reliability, enhancing performance, and reducing operational costs. The next generation reactor technologies with passive safety features will benefit from the development and application of new I&C technologies. Some of these new designs raise extreme environmental challenges such as high temperatures (over 1,400 °C) and material compatibility (e.g., molten salts).
