W19  Improving Confidence in Probabilistic Fracture Mechanics - Part 2: Regulatory Applications

Probabilistic fracture mechanics (PFM) tools are becoming more frequently used in nuclear applications to directly account for uncertainties and reduce conservatisms in structural integrity assessments of passive components such as piping and vessels. The proper development and use of these codes, including uncertainty characterization and propagation, is essential to providing regulatory confidence in the final result. This session focuses on the application of probabilistic fracture mechanics in the nuclear field. In particular, speakers will discuss probabilistic fracture mechanics applications for piping in nuclear plants. Speakers will also give examples of past uses of probabilistic fracture mechanics for regulatory analysis in the United States.
