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 submittal available for review. The NRC encourages applicants to discuss the contents of their submittal with the agency during pre-submittal meetings (the timing of such meetings is left to the applicant, but it could be desirable to schedule such meetings early in the lifecycle of the application) or other formal communications. Pre-submittal discussions should cover information that will be provided with the submittal, information that might be provided upon request, and information that may not be directly transmittable but might be reviewed under specific agreed-upon circumstances, such as an audit. RG 1.245 Revision 0, Page 11 2.2.1 Probabilistic Fracture Mechanics Software In case the NRC staff determines that it is unable to perform independent confirmatory calculations or independent benchmarking of the PFM analyses, the applicant should ensure that an alternate approach is available to NRC reviewers. This will preferably be determined during preapplication meetings but can also be identified during the review. Such approaches may include one or more of the following options: • Provide NRC reviewers with direct access to the PFM software executable program and the necessary user instructions to use the tools. • Ensure the availability of analysts during NRC audits or NRC review meetings, such that the PFM submittal developers can run analysis cases as requested by NRC reviewers. • Allow the NRC reviewers to submit analysis requests to the applicant and provide the NRC reviewers with the results of the analyses, possibly as part of an audit or review meeting. 2.2.2 Probabilistic Fracture Mechanics Software Quality Assurance and Verification and Validation Documents The applicant should ensure that the SQA and V&V documentation for the PFM software is
