Nuclear power plants - Instrumentation and control systems - Requirements for coordinating safety and cybersecurity

IEC 62859:2016+A1:2019 provides a framework to manage the interactions between safety and cybersecurity for nuclear power plant (NPP) systems, taking into account current IEC standards addressing these issues and the specifics of nuclear I&C programmable digital systems. This standard establishes requirements and guidance to:

- integrate cybersecurity provisions in nuclear I&C architectures and systems, which are fundamentally tailored for safety;

- avoid potential conflicts between safety and cybersecurity provisions;

- aid the identification and the leveraging of the potential synergies between safety and cybersecurity.

This consolidated version consists of the first edition (2016) and its amendment 1 (2019). Therefore, no need to order amendments in addition to this publication.
