摘要

This Nuclear Energy Research Initiative (NERI) project was tasked with exploring, adapting, developing, and demonstrating innovative nondestructive test methods to automate the inspection of coated nuclear fuel particles. The United States (U.S.) requires improved, economical, inspection methods for Quality Assurance and Quality Control (QA/QC) of fuel production for several reactor concepts being proposed for both near-term deployment (DOE-NE & NERAC, 2001) and Generation IV nuclear systems. Replacing existing QA/QC methods (performed manually and, in most cases, destructively) with higher-speed, automated, nondestructive methods will make fuel production for advanced reactors economically feasible. For successful deployment of next-generation reactors that employ particle fuels, or fuels in the form of pebbles based on particles, extremely large numbers of fuel particles will require inspection at throughput rates that do not significantly impact the proposed manufacturing processes. This project was focused on nondestructive examination (NDE) technologies that can be automated for production speeds and that can be utilized for either in-line measurements or on-process measurements. The inspection technologies selected for evaluation and development were considered potentially capable of providing a 'quality' assessment of an individual particle or group of particles as those particles pass a sensor. A goal was to define a multiple-attribute signature that could be measured and used for qualification or process control decisions. A primary task in addressing that objective was to establish standard signatures for acceptable particles and for the most problematic types of defects.
