.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 Evaluation and Acceptance of Commercial Grade Digital Equipment for Nuclear Safety Applications,” as accepted by the NRC safety evaluation dated July 17, 1997, and EPRI TR-107330, “Generic Requirements Specification for Qualifying a Commercially Available PLC for Safety-Related Applications in Nuclear Power Plants,” as accepted by the NRC safety evaluation dated July 30, 1998 provide guidance for the evaluation of existing commercial computers and software to comply with the criteria of Clause 5.3.2 of IEEE Std 7-4.3.2. The guidance of SRP BTP 7-14, “Guidance on Software Reviews for Digital Computer-Based Instrumentation and Control Systems,” may be applied to the evaluation of vendor processes described in EPRI TR-106439. The software tools clause was revised to address the expanded use of software tools and methods to confirm suitability. International Electrotechnical Commission (IEC) 60880-2-2002, “Software for Computers Important to Safety for Nuclear Power Plants - Part 2, “Software Aspects of Defense Against Common Cause Failures, Use of Software Tools and of Pre- developed Software,” specifically addresses the use of software tools. If, however, it cannot be demonstrated that defects not detected by software tools or introduced by software tool will be detected by V&V activities, the software tool should be designed as safety related software itself, with all the attendant regulatory requirements for safety software. IEEE Std 7-4.3.2, Clause 5.3.2 recommends that software tools used to support software development and V&V processes should be controlled under CM; and that one or both of the following methods should be used to confirm that the software tools are suitable for use: (a) A test tool validation program should be developed to provide
