Nuclear power plants

Instrumentation, control and electrical power systems important to safety – Categorization of functions and classification of systems

(IEC 61226:2020); German version EN IEC 61226:2021
Class/Status: Standard, valid
Released: 2022-09
VDE Art. No.: 0400533

This standard describes a method for classification of information and control functions and the systems and equipment related to those functions. The classification is according to the significancy of the functions to the safe operation of the power plant. The functions are assigned to Categories A, B, C or "not classified" depending on their contribution to the prevention and mitigation of postulated initiating events (PIE).
