A verification and validation (V&V) process has been performed for the System Analysis Programs for Hands-on Integrated Reliability Evaluation (SAPHIRE).SAPHIRE is a set of four computer programs that the Nuclear Regulatory Commission (NRC) has developed for the performance of probabilistic risk assessments (PRAs). These programs allow an analyst to perform many of the functions necessary to create, quantify, and evaluate the risk associated with a facility or process being analyzed. The programs included in this set are Integrated Reliability and Risk Analysis System (IRRAS), System Analysis and Risk Assessment (SARA), Models and Results Database (MAR-D), and Fault Tree/Event Tree/Piping and Instrumentation Diagram (FEP) graphical editor.There were several steps to the V&V. A V&V plan was prepared to describe the process and criteria by which the V&V would be performed. The software requirements documentation was reviewed to determine the correctness, completeness, and traceability of the requirements. A user survey was conducted to determine the usefulness of the user documentation.Vital and non-vital features were identified and tested. The testing that was performed and the results that were obtained were documented.The results indicate improvements are needed in the software requirements documentation and in the user documentation. The majority of the results from the testing were acceptable; however, some discrepancies between expected code operation and actual code operation were identified. The discrepancies were provided to the code developers. Modifications that will be made to SAPHIRE are identified.
A verification and validation (V&V) process has been performed for the System Analysis Programs for Hands-on Integrated Reliability Evaluation (SAP=) Version 5.0. SAPHIRE is a set of four computer programs that the Nuclear Regulatory Commission has developed for the performance of probabilistic risk assessments. These programs allow an analyst to perform many of the functions necessary to create, quantify, and evaluate the risk associated with a facility or process being analyzed. The programs included in this set are Integrated Reliability and Risk Analysis System (IRRAS), System Analysis and Risk Assessment (SARA), Models And Results Database (MAR-D), and Fault tree, Event tree, and Piping and instrumentation diagram (FEP) graphical editor. The intent of this program is to perform a V&V of successive versions of S A P H U E Previous efforts have been the V&V of SAPHIRE Version 4.0. The SAPHIRE 5.0 V&V plan is based on the SAPHIRE 4.0 V&V plan with revisions to incorporate lessons learned from the previous effort Also, the SAPHIRE 5.0 vital and nonvital test procedures are based on the test procedures from SAPHIRE 4.0 with revisions to include the new SAPHIRE 5.0 features as well as to incorporate lessons learned from the previous effort. The majority of the results from the testing was acceptable; however, some discrepancies between expected code operation and actual code operation were identified. Modifications that have been made to SAPHIRE are identified.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
