Nuclear power plants. Instrumentation and control systems important to safety. Surveillance testing Ingestion-build-73073 When these insulating liquids are1 Scope Where functional reliability is required by general safety standards, one aspect of demonstrating this reliability is testing performed on line during plant operation or during plant shutdown in preparation for return to power operation. This standard lays down principles for testing I&C systems performing category A, B and C functions, per IEC 61226, during normal power operation and shutdown, so as to check the functional availability
