are. The second (optional) part, if the applicant or licensee relies on a software vendor to perform certain maintenance functions, consists of the associated vendor’s procedures. The SMaintP should include procedures for problem reporting, and for resolution of those problem reports. The problem reporting procedure should give time and date of occurrence, a brief description of the problem (including the state of the system at the beginning of the occurrence) and a description as to what was done to correct the problem. It should require that reported problems be evaluated to allow the identification of nonconforming items and the performance of corrective actions as described in Sections XV and XVI of 10 CFR Part 50, Appendix B. The SMaintP should describe the process for identification, documentation, evaluation, segregation where practical, and disposition of nonconforming items, and for notification to affected organizations. Evaluation of nonconforming items and corrective actions should include as appropriate evaluation with respect to the requirements of 10 CFR 50.59, “Changes, Tests and Experiments,” and reporting per the requirements of 10 CFR Part 21, “Reporting of Defects and Noncompliance.” Operability determinations should be made as part of the SOP. Nonconformance to design requirements dispositioned “use-as-is” or “repair” should be subject to design control (including verification and validation, quality assurance, safety analysis, and configuration management) measures commensurate with those applied to the original design. BTP 7.14-30 Revision 6 - August 2016 The SMaintP should require that as-built records reflect any accepted deviations and justification for that acceptance. Because any error in safety system software presents the potential for common-cause failure of redundant functions, the SMaintP should require timely evaluation of the effects of reported problems to support equipment operability determinations as required
