Overview
IEC 63413:2026 is an international standard developed by the International Electrotechnical Commission (IEC) that provides requirements and guidance for the qualification of instrumentation and control (I&C) platforms used in nuclear power plants, specifically those important to safety. The focus is on the generic qualification of I&C platforms-sometimes referenced as pre-qualification or platform qualification-performed independently from any plant-specific application project. By establishing a robust platform qualification, this standard aims to facilitate a two-step licensing approach for I&C systems in nuclear applications: (1) platform suitability and (2) plant-specific system implementation.
Key aspects of platform qualification covered in this standard include the evaluation of hardware, software, programmable logic (such as HDL-programmed devices), engineering tools, environmental resilience, quality assurance, and the entire safety life cycle. IEC 63413:2026 applies to both newly developed and pre-existing I&C platforms, providing clarity on the boundary between platform qualification and system-specific implementation.
Key Topics
-
Platform Qualification Requirements:
- Addresses the organization and process for qualifying I&C platforms, ensuring independence from plant-specific implementation.
- Covers all aspects including hardware, software, engineering tools, environmental and seismic qualification, and interaction of platform assemblies.
- Refers to relevant IEC standards for specific requirements (e.g., hardware per IEC 60987, software per IEC 60880/62138).
-
Safety Life Cycle:
- Outlines how the qualification activity supports the safety-oriented development life cycle per IEC 61513.
- Emphasizes verification, validation, and quality management activities.
-
Use of Qualified Platforms:
- Provides guidance distinguishing platform qualification from the implementation of plant-specific I&C system designs.
- Facilitates evidence-based licensing and regulatory approval, by separating generic platform assessment from system-specific qualification.
-
Seismic and Environmental Qualification:
- Recognizes the importance of demonstrating platform resilience to operational and accidental conditions.
- Guides the application of standards for environmental and seismic qualification (IEC/IEEE 60780-323, IEC/IEEE 60980-344).
-
Harmonization and Cybersecurity:
- Aligns platform qualification with referenced standards for cybersecurity (IEC 62645) and quality frameworks (ISO 9001, IAEA safety guides).
- Ensures adoption of consistent terminology and processes as recommended by the broader IEC SC 45A series.
Applications
IEC 63413:2026 is essential for various stakeholders in the nuclear sector:
-
Nuclear Power Plant Designers and Operators
Utilize the standard to qualify I&C platforms before deploying plant-specific systems, streamlining the design and licensing processes.
-
Vendors and System Integrators
Demonstrate the suitability of configurable and pre-existing I&C platforms for safety-related applications in different nuclear sites worldwide.
-
Regulators and Assessors
Reference the standard to establish compliance frameworks for platform qualification, ensuring all safety requirements are met and simplifying the review process.
-
Independent Evaluators and Certification Bodies
Apply the requirements of IEC 63413:2026 to perform audits, assessments, and certification of I&C platforms crucial to nuclear safety.
The standard ensures that, through comprehensive pre-qualification, only thoroughly evaluated platforms are used as the foundation for safety-critical system design in nuclear power plants. This approach improves efficiency, mitigates risks, and supports international harmonization across nuclear projects.
