IEC 63413:2026 pdf download,Nuclear power plants – Instrumentation and control systems important to safety – Platform qualification.
IEC 63413:2026 is the first edition international standard that establishes requirements and guidance for the qualification of safety‑important instrumentation and control (I&C) platforms in nuclear power plants. It applies generically to both new and existing I&C platforms, independent of specific plant projects, often called “pre‑qualification” or “generic qualification”.
The standard covers the entire I&C platform, including hardware, software, human‑machine interfaces (HMI), engineering tools, and environmental qualification, along with quality management and safety lifecycle processes. It addresses platform‑level interactions and ensures all elements meet nuclear safety criteria before plant‑specific deployment.
A core objective is to enable a two‑step licensing approach: generic platform qualification first, followed by plant‑specific application qualification, reducing redundant effort and accelerating deployment. It defines qualification activities, acceptance criteria, documentation, and test requirements to verify robustness against harsh conditions (e.g., radiation, temperature, vibration).
It excludes system‑level qualification done entirely within a single plant project. As a key nuclear I&C standard, it supports manufacturers, utilities, and regulators in ensuring that digital and analogue control platforms are reliable, safe, and fit‑for‑purpose in nuclear safety‑critical applications worldwide.
