function, or shall be demonstrated to be acceptable on some other defined basis. Design techniques, such as functional diversity or diversity in component design and principles of operation, shall be used to the extent practical to prevent loss of the protection function.” Applicability - The protection systems, RTS, ESFAS, and supporting data communication systems. Review Methods - Review of compliance with GDC 22 should address the characteristics listed in the table below. These characteristics are described in IEEE Std. 279-1971 and IEEE Std. 603-1991, and methods for reviewing them are discussed in SRP Appendix 7.1-B and SRP Appendix 7.1-C (see table below for section).

Review Methods - Review of compliance with GDC 23 is accomplished as part of the review of system integrity requirements discussed in IEEE Std. 279-1971 and IEEE Std.
