Safety-Class and Safety-Significant SSCs; other systems that perform important defense-in-depth functions; and equipment relied on for the safe operation and safe shutdown of the nuclear facility, and for maintaining the facility in a safe shutdown condition as documented in the safety basis (e.g., DSA). Support systems to Safety SSCs that are required for the safety functions are also included.
