Abstract

Post nuclear accident conditions represent a harsh environment for electronics. Three Mile Island, Chernobyl, and Fukushima Daiichi show the necessity for emergency sensing capabilities in a radiation-enhanced environment. Each proved dangerous to workers trying to assess, control and mitigate the accidents. Robots were used in each case with limited success. Consequently, research into methods to extend the life of robots in a high radiation environment has become a priority for industry. Robotic systems can be utilized to inspect, repair, and monitor facilities within the entire nuclear fuel cycle. This paper investigates the total ionizing dose (TID) hardness of electronics using available technology employing commercial off-the-shelf devices and present generation circuit fabrication techniques. Our approach is to develop system level mitigation techniques for circuits destined for severe nuclear environments. We aim to increase the radiation resilience of sensitive electronics such that a robot could be employed for in-containment post-accident monitoring and sensing purposes.
