Nuclear power plants, Instrumentation and control systems important to safety, Software aspects for computer-based systems performing category A functions
This document provides requirements for the software of computer-based Instrumentation and Control (I&C) systems of nuclear power plants performing functions of safety category A as defined by IEC 61226. As an IEC/IEEE standard developed according to the Dual Logo Agreement, when used within the context of IEEE, this document provides an acceptable set of requirements for achieving the quality and reliability objectives for the software used in IEEE Class 1E safety systems, subsystems, and components. According to the definition in IEC 61513, I&C systems of safety class 1 support category A functions, but may also support functions of lower categories. However the system requirements are always determined by the functions of the highest category implemented. For software of I&C system performing only category B and C functions in Nuclear Power Plants (NPP) as defined by IEC 61226, the requirements and guidance of IEC 62138 are applicable. This document provides requirements for the purpose of achieving highly reliable software. It addresses each stage of software generation and documentation, including requirements specification, design, implementation, verification and validation testing. The principles applied in developing these requirements include: – best available practices; – top-down design methods; – modularity; – verification of each phase; – clear documentation; – auditable documents; – validation testing. Annex A provides detailed requirements and recommendations for design and implementation of software. Additional informative guidance is given in Annex B to Annex G. This document does not explicitly address how to protect software against those threats arising from malicious attacks, i.e. cybersecurity, for computer-based systems. IEC 62645 provides cybersecurity requirements. IEC 62671 may be used as an alternative to this document for digital devices of limited functionality. IEC 62671 contains precise criteria to determine if it is applicable to a particular device.

Nuclear Power Plants - Instrumentation, Control and Electrical Power Systems Important to Safety - Common Cause Failure Systems Analysis and Diversity
This standard establishes the principles of analysis for and the documentation of the defenses provided against Common Cause Failure (CCF) of Electrical, Instrumentation and Control systems in nuclear facilities. It covers CCF from hazards and also from systematic faults. The standard does not provide requirements on detailed design or of acceptance criteria for the adequacy of CCF defense.
P7-4.3.2
IEEE Draft Standard Criteria for Programmable Digital Devices in Safety Systems of Nuclear Power Generating Stations
Additional specific requirements to supplement the criteria and requirements of IEEE Std 603™ are specified for programmable digital devices. Within the context of this standard, the term programmable digital device is any device that relies on software instructions or programmable logic to accomplish a function. Examples include a computer, a programmable hardware device, or a device with firmware. Systems using these devices will also be referred to as digital safety systems in this standard. The criteria contained herein, in conjunction with criteria in IEEE Std 603™, establish minimum functional and design requirements for programmable digital devices used as components of a safety system.
Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.
7-4.3.2-2016
IEEE Standard Criteria for Programmable Digital Devices in Safety Systems of Nuclear Power Generating Stations
Additional specific requirements to supplement the criteria and requirements of IEEE Std 603(TM) are specified for programmable digital devices. Within the context of this standard, the term programmable digital device is any device that relies on software instructions or programmable logic to accomplish a function. Examples include a computer, a programmable hardware device, or a device with firmware. Systems using these devices will also be referred to as digital safety systems in this standard. The criteria contained herein, in conjunction with criteria in IEEE Std 603, establish minimum functional and design requirements for programmable digital devices used as components of a safety system
These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.
7-4.3.2-2003
IEEE Standard Criteria for Digital Computers in Safety Systems of Nuclear Power Generating Stations
Additional computer specific requirements to supplement the criteria and requirements of IEEE Std 603-1998 are specified. Within the context of this standard, the term computer is a system that includes computer hardware, software, firmware, and interfaces. The criteria contained herein, in conjunction with criteria in IEEE Std 603-1998, establish minimum functional and design requirements for computers used as components of a safety system.
