ICS Code (Nuclear power plants. Safety): 27.120.20
scope:

This standard gives recommendations on the necessary properties of components to be used in electrical and I & C systems important to safety deployed in nuclear power plants. These properties are assessed in terms of the constraints with regard to I & C and plant engineering in order to ensure that, depending on the existing and/or planned design features, components with suitable quality features are used.

For this purpose, the standard specifies the fundamental requirements which commercial grade products with high integrated components or embedded software have to meet. It shows which additional measures and/or constraints are necessary if they are to be used for the functions of I & C systems important to safety. The aim here is to also use components qualified in accordance with industrial codes and standards in order to implement I & C systems of equivalent reliability. To achieve this, it is frequently necessary to set up additional requirements on system design.

For example, suitable transferability studies allow properties already verified via a qualification for safety control systems in accordance with DIN EN 61508 to be taken as a basis for using the latter in nuclear facilities with or without an additional qualification depending on the application.

This standard contains the general requirements and criteria for use. The following parts will specify in detail the requirements and criteria for individual product groups depending on their intended safety function and their significance in the context of the plant as well as the typical product structure and the constraints for use.

The recommendations given in this standard refer to the construction or modification of electrical and I & C systems in nuclear power plants. The functions of these systems are classified in accordance with categories 1 to 3 of RSK-LL or categories A to C of DIN EN 61226. The recommendations given in the standard are to be applied in addition to system design standards such as RSK-LL, KTA 3501, DIN EN 61513, DIN EN 60880, and DIN EN 62138.

The recommendations concern all components required in order to perform I & C functions. These range from sensors, measuring transducers and processing units to switching equipment and protective devices, and I & C components of drives (e.g. for feedback purposes). The recommendations given in the standard thus cover the construction or replacement of a complete I & C system as well as the replacement of individual peripheral components by a different type.
