(k) GDC 22, “Protection System Independence” “The protection system shall be designed to ensure that the effects of natural phenomena, and of normal operating, maintenance, testing, and postulated accident conditions on redundant channels do not result in loss of the protection 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 - The review of compliance with GDC 22 should
