Content:
to the areas of unknown code capability. • Describe features of the specific application where the code has not been previously validated and applied (i.e., areas of unknown code capability). QV-1C Modified • Give an SQA summary and V&V description for modified portions of the code. • Demonstrate that the code was not “broken” as a result of changes. • Make detailed documentation available for further review upon request (audit). QV-2 Commercial off-the-shelf software designed for the specific purpose of the application b • Demonstrate code applicability. • Describe the software and its pedigree. • Make software and documentation available for review upon request (audit). QV-3 Custom code • Summarize the SQA program and its implementation. • Provide a basic description of the measures for quality assurance, including V&V of the PFM analysis code as applied in the subject report. • For very simple applications, possibly provide the source code instead of standardized SQA and V&V. • Include separate deterministic fracture mechanics analyses to support other validation results, as appropriate for a given application. a As of the publication of this RG, PFM codes used in NRC-approved applications or having received general approval within a validated range include xLPR, FAVOR, and SRRA. b Examples would include publicly available (for purchase or free) commercial software specifically to perform PFM analyses. Combinations of commercial off-the-shelf software may be acceptable (e.g., a finite-element software such as ABAQUS or ANSYS coupled with a probabilistic framework such as GoldSim or DAKOTA). RG 1.245 Revision 0, Page 14 2.5. Models The applicant should describe all the models implemented and used as part of the PFM analysis and software. Each model should be assessed independently and categorized as shown in Table C-3. The applicant should follow the submittal guidelines in Table C-3 for each model in the PFM software and/or analysis,
