IEC 62003-2020 Nuclear power plants — Instrumention, control and electrical power systems — Requirements for electromagnetic compatibility testing

IEC 62003-2020 Nuclear power plants — Instrumention, control and electrical power systems — Requirements for electromagnetic compatibility testing. This document establishes requirements for electromagnetic compatibility testing of instrumentation, control, and electrical equipment supplied for use in systems important to safety at nuclear power plants and other nuclear facilities. The document lists the applicable IEC standards (principally the IEC 61 000 series) which define the general test methods, and provides the necessary application-specific parameters and criteria to ensure that nuclear safety requirements are met. The normative part of this document is limited to the testing of equipment prior to installation in a nuclear power plant to demonstrate immunity to electromagnetic disturbances and to demonstrate that the equipment does not generate excessive emissions. Testing for the generation of excessive emissions is also applicable to non-safety equipment. This document includes informative annexes which provide additional guidance and describes approaches to maintaining electromagnetic compatibility for installed equipment. The intent of this document is to provide guidance for conducting the electromagnetic compatibility (EMC) qualification testing of the equipment and does not provide guidance for the installation of the equipment to prevent electromagnetic and radio frequency interference (EMI/RFI). However, the configuration of the equipment under test during EMC qualification testing is representative of the intended installation in a nuclear facility. Protection against a high altitude electromagnetic pulse (HEMP) and intentional electromagnetic interference (IEMI) are outside of the scope of this document, but information can be found in IEC 61 000-4-23, IEC 61 000-4-24, and IEC 61 000-4-25 (HEMP) and IEC 61 000-4-36 (IEMI) to address these phenomena. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.
