EN IEC 62645:2020 protects the cybersecurity of nuclear power plants

The risk of cybersecurity threats on computer-based equipment and programmable logic devices used in industrial installations is always topical. In particular, IT equipment has been widely implemented also in nuclear power plants (both existing and newly built ones) to perform operational and safety functions. Therefore, the protection of nuclear power plants against cybersecurity threats is of particular importance to ensure plant safety and operation.

The IEC Subcommittee 45A (IEC – TC 45/SC 45A) on ‘Instrumentation, control and electrical power systems of nuclear facilities’, which is mirrored  at European level by CLC/TC 45AX ‘Instrumentation, control and electrical power systems of nuclear facilities’, whose Secretariat is currently held by AFNOR, has been developing a cybersecurity standards framework. This framework is based on the ISO/IEC 27000 series and the security series of the International Atomic Energy Agency (IAEA).
