rovided in the design of the digital system to meet the criteria established by NRC requirements, (2) to verify that adequate defense-in-depth has been provided to meet NRC criteria, and (3) to verify that the displays and manual controls for critical safety functions initiated by operator actions are diverse from the computer systems used in the automatic actuation of plant safety systems. 5.2. Completion of Protective Action (IEEE Std 7-4.3.2, Clause 5.2) The reviewer should refer to Subsection 5.2 of SRP Appendix 7.1-C for guidance on the implementation of the requirements of IEEE Std 603-1991. 5.3. Quality (IEEE Std 7-4.3.2, Clause 5.3) The applicant or licensee should confirm that the quality assurance provisions of Appendix B, “Quality Assurance Criteria for Nuclear Power Plants and Fuel Reprocessing Plants,” to 10 CFR Part 50, “Domestic Licensing of Production and Utilization Facilities,” are applied to the safety system. The evaluation of the adequacy of the quality assurance program is addressed in the review of Chapter 17 of the SAR. Appendix 7.1-D-5 Revision 1 - August 2016 For digital computer-based systems, the applicant/licensee should address the quality criteria described in Clause 5.3 of IEEE Std 7-4.3.2. Hardware quality is addressed in IEEE Std 603-1991. Software quality is addressed in IEEE/Energy Information Administration (EIA) Std 12207.0-1996, “IEEE Standard for Software Life-Cycle Processes and Supporting Standards.” In addition to the requirements of IEEE Std 603-1991, the following activities necessitate additional criteria that are applicable to the quality criterion. The criteria are provided in the following clauses of IEEE Std 7-4.3.2: 5.3.1 Software development 5.3.2 Software tools 5.3.3 Verification and validation (V&V) 5.3.4 Independent V&V requirements 5.3.5 Software configuration management (CM) 5.3.6 Software project risk management Electric Power Research Institute (EPRI) Topical Report (TR)-106439, “Guideline on
