f software V&V, including elements of software V&V plan (SVVP), and describes a minimum set of V&V activities for software at different integrity levels. IEEE Std. 1028-2008 is a process standard that provides guidance for conducting technical and management reviews, inspections, walkthroughs, and audits. With consideration of the different standards used in software development the applicant or licensee should consider the hierarchy of the different standards for guidance. IEEE Std. 1074-2006, “IEEE Standard for Developing Software Life Cycle Processes” (Ref. 13), as noted in Regulatory Guide 1.173, “Developing Software Life Cycle Processes for Digital Computer Software in Safety Systems of Nuclear Power Plants” (Ref. 14), should be reviewed as the main outline standard when working with this regulatory guide. This regulatory guide is based on standards and describes methods acceptable for any safety system software and discusses the required V&V activities. The applicant or licensee determines how the required activities will be implemented. Other Codes and Standards This regulatory guide endorses the use of one or more voluntary consensus codes or standards developed by external organizations. These codes or standards may contain references to other codes or standards. These references should be considered individually. If a referenced standard has been incorporated separately into NRC regulations, licensees and applicants must comply with that standard as set forth in the regulation. If the referenced standard has been endorsed in a regulatory guide, the standard constitutes a method acceptable to the NRC staff for meeting a regulatory requirement as described in the specific regulatory guide. If a referenced standard has been neither incorporated into NRC regulations nor endorsed in a regulatory guide, licensees and applicants may consider and use the information in the referenced standard, if appropriately justified and consistent with current
