Currently, the process of conducting frequent radiation surveys of large and complex areas, such as nuclear power plants, shipping ports, and urban areas, is a labor intensive process that puts personnel at risk of being exposed to unnecessary dose. Collecting and correlating large amounts of radiation data, situational awareness or environmental data from multiple sensors ranging from visual cameras, LiDAR, GPS, and more, is also a labor intensive process that is error prone. Currently deployed robotic systems with multi-sensor payloads collect data independently and require the end user to manually analyze the data. Advanced software and hardware tools are required to enable more intelligent integration of sensors with robotic platforms and automate the correlation, analysis, and fusion of these different types of data to quickly provide actionable information for applications ranging from civil nuclear power to emergency response. This Phase I effort will focus on the development of an intelligent integration package to maximize the powerful capabilities of 3D, real-time mapping, radiation and multisensor data fusion, and visualization technologies with advanced robotics equipped with autonomous operation and obstacle avoidance. This effort will also support development of a complementary automated comparative data analysis software package, which will enable change detection or trend analysis. This software package will be capable of analyzing changes in radioisotope and dose rate data over time and space and providing actionable insights to end users, and the integration of additional sensor data will also be investigated. The end result of this effort is an autonomous and intelligent data collection and analysis capability that will enable safer, more efficient, and more economical operation of the existing U.S. nuclear fleet and the next generation of advanced nuclear reactors. There are significant commercial opportunities to implement the proposed capabilities across the U.S. nuclear fleet to automate plant monitoring, radiation protection, and operational work processes. The results of this SBIR will support both the National Reactor Innovation Centers efforts to develop complementary innovations that will support sustainability of new advanced nuclear reactor technologies, including advanced robotics with multisensor systems, as well as the DOEs Light Water Reactor Sustainability Program efforts to replace labor-intensive operations with safer, automated data collection and analysis tools under the Plant Monitoring and Work Process Automation focus area. These capabilities will also enable safer, faster, and more efficient radiation detection, assessment, and response for other applications, including decommissioning, emergency response, homeland security, defense, and international safeguards.
