uld include as appropriate evaluation with respect to the requirements of 10 CFR 50.59 and reporting per the requirements of 10 CFR 21. Nonconformances 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. The plan 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-mode failure of redundant functions, the maintenance plan should require timely evaluation of the effects of reported problems to support equipment operability determinations as required by plant technical specifications. Periodic analysis and reporting of problems and their resolution should be required along with recommendations for improving operation. There should be a requirement for reporting what actions were taken regarding these recommendations. Resource Characteristics The resource characteristics that the software maintenance plan should exhibit include methods/tools. Methods/tools requires a description of the methods, techniques and tools that will be used to accomplish the maintenance function. The plan should describe the facilities required to maintain the delivered software. It should list and describe the software, hardware and associated documentation required to maintain the delivered software. The plan should require that maintenance tools be qualified with a degree of rigor and level of detail appropriate to the safety significance of the software which is to be created using the tools. g. Software Training Plan The software training plan should exhibit the management, implementation, and resource characteristics listed below.
