Nuclear power plants - Instrumentation, control and electrical power systems important to safety - Categorization of functions and classification of systems
standard by International Electrotechnical Commission, 04/29/2020
Full Description
IEC 61226:2020 establishes a method of classification of the information and command functions for nuclear power plants, and the instrumentation and control systems and equipment that provide those functions, into categories that designate the importance to safety of the function. The resulting classification then determines relevant design criteria. Is applicable to all the information and command functions and the instrumentation and control systems and equipment that provide those functions.
