Surveillance Of Items Important To Safety In Nuclear Power Plants

Provides recommendations and guidance for effective maintenance, surveillance and in-service inspection to ensure that the levels of reliability and availability of all plant structures, systems and components meet the assumptions and intent of the design.

This guide gives design guidance on requirements for the protection system which monitors the relevant plant variables and performs - in conjunction with the safety actuation systems and safety system support features - all safety tasks that may become necessary when unacceptable.

Establishes design requirements for safety functions and associated structures, systems and components important to the safe operation of nuclear power plants. This publication also establishes requirements for a comprehensive safety assessment to identify the potential hazards that may arise in the operation of plants.
