ately implementing the change, or scheduling the change for a future version). There may be two different software configuration management programs to evaluate, that being used by the software vendor during the design process, and that used by the licencee after the software has been delivered and installed in the nuclear power plant. Both of these Appendix 7.1-D-13 March 2007 programs should be evaluated. Appendix B of 10 CFR Part 50, in Section I, “Organization”, states, “The applicant may delegate to others, such as contractors, agents, or consultants, the work of establishing and executing the quality assurance program, or any part thereof, but shall retain responsibility therefor.” The reviewer should determine if a vendor software configuration management program has been approved by the licensee, and if it fits into the licensee’s overall software configuration management program. IEEE Std 828-1990 and IEEE Std 1042-1987, which are endorsed by Regulatory Guide 1.169, should provide acceptable guidance for a software configuration management system, but the use of these standards is not mandatory. If referenced by the licensee, the reviewer should make an independent determination that the software configuration management system as implemented is appropriate for safety-related software used in nuclear power plants. If the vendor or licensee is using methods other than that prescribed by IEEE Std 828-1990 and IEEE Std 1042-1987, the determination of adequacy will be more difficult. In this case, the reviewer should be familiar with the software configuration control objectives, and examine the methodology used by the vendor and licensee in sufficient detail to determine that an equivalent level of control is provided as those that would have been provided by previously reviewed and approved methods, such as those found in IEEE Std 828-1990 and IEEE Std 1042-1987. The reviewer of the software configuration management system should evaluate that the
