Probabilistic Fracture Mechanics Analysis and Submittal Contents Each subsection in this Regulatory Position relates to an item expected in a submittal. The content in each subsection comes from, in large part, the suggested minimum content for PFM submittals that was developed in EPRI’s white paper (Ref. 17). Tables in each subsection provide guidance for different documentation expectations. Each table contains circumstances under which specific information should be provided for a complete submittal. It is important to note that submittals should be informed by the specific details and elements of each analysis and need not include all of the listed elements, though careful consideration should be applied to arrive at that conclusion. 2.1. Regulatory Context Regulatory submittals using PFM analyses should explain why a probabilistic approach is appropriate and how the probabilistic approach is used to demonstrate compliance with the regulatory criteria. When no specific regulatory acceptance criteria exist, the submittal should explain how the probabilistic approach informs the regulatory action and regulatory compliance demonstration. Applicants should be aware that the use of PFM in a regulatory submission is only one aspect of what is required for risk-informed decision making. 2.2. Information Made Available to the NRC Staff with a Probabilistic Fracture Mechanics Submittal Applicants should make information supporting the
