The guidance and conclusions provided in this report are the result of a multi-year effort to understand the potential role of modeling and simulation in improving the efficiency and efficacy of ultrasonic inspections of nuclear power plant components. Conclusions are coalesced from previous work, and strategies and best practices are suggested for successful implementation of modeling and assessment of simulation outcomes. An overview of challenges in modeling and simulation is given, along with strategies for overcoming these challenges. Methods of validation and verification are outlined to help assure that models and simulation outcomes are reliable. Specific direction for implementing the models is provided as well as guidance for assessing the outcomes. In addition, key takeaways and lessons learned for different modeling scenarios are listed. The guidance and conclusions summarized in this report are intended to form the technical framework for development of a nondestructive evaluation modeling and simulation best practices document that will support standardization of modeling practices across the commercial nuclear power industry.
