e two different software CM programs to evaluate, that being used by the software vendor during the design process, and that used by the licensee after the software has been delivered and installed in the nuclear power plant. Both of these 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 for the quality assurance program.” The reviewer should determine if the vendor’s software CM program has been approved by the licensee, and if it fits into the licensee’s overall software CM program. IEEE Std 828 which is endorsed by RG 1.169, (subject to certain provisions) provides acceptable guidance for a software CM 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 CM system as implemented is appropriate for safety-related software used in nuclear power plants. If the vendor or licensee is using methods other than those prescribed by IEEE Std 828, the determination of adequacy will be more difficult. In this case, the reviewer should be familiar with the software configuration control objectives, and should 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. The reviewer of the software CM system should evaluate that the system used by both the vendor and the licensee ensures that any software modifications during the design process and after acceptance of the software for use will be made to the appropriate version and revision of the software. This will involve not only a review of the software CM
