ve been specified, and that filter properly designed and implemented. However, if the filter does not actually filter the required frequencies, or does not actually reduce or eliminate the noise it is intended to filter, the quality of the V&V effort is suspect. Appendix 7.1-D-13 Revision 1 - August 2016 iv. Are the V&V problem reports properly addressed, corrections made, and the resulting correction itself properly checked? There have been cases where a V&V problem report was not effectively resolved, or where the correction resulting from a V&V problem report was in itself in error, and the analysis for the correction was so limited that the new error was not found. The reviewer should check the problem reports carefully, and determine that each problem was addressed and that correction did, in fact, the correct the problem without introducing new errors. The review of the V&V is an important step in the determination of high quality software and a high quality design process, and as such, any concerns the reviewer has about the quality of the V&V effort should be resolved prior to acceptance of the digital system. If the reviewer identifies concerns with quality or effectiveness, those issues should be raised to NRC management to determine the next steps up to and including non-acceptance of the V&V effort of the digital system for use in a safety-related application at nuclear power plants. 5.3.5 Software Configuration Management (IEEE Std 7-4.3.2, Sub-Clause 5.3.5) RG 1.169, “Configuration Management Plans for Digital Computer Software Used in Safety Systems of Nuclear Power Plants,” which endorses IEEE Std 828, “IEEE Standard for Software Configuration Management Plans,” (subject to certain provisions) provides guidance for the development of software CM plans. SRP BTP 7-14, Subsection B.3.1 provides additional guidance on CM plans, and Subsection B.3.2 provides additional guidance on CM activities. The minimum set of activities should address the
