Nuclear power plants. Instrumentation and control systems important to safety. Surveillance testing Ingestion-build-489741 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

BS EN 60076-5 describes the calculation procedures used to demonstrate the thermal ability of a power transformer to withstand such overcurrents and both the special test and the theoretical evaluation method are used to demonstrate the ability to withstand the relevant dynamic effects
