It replaces the first edition and also the second part published in 2000, which was integrated into the new edition so that it covers all of the most important software safety issues that need to be addressed.

The standard was developed by IEC Subcommittee 45A - instrumentation and control of nuclear facilities.

"Although many of the requirements described in the first edition continued to be relevant, reasons for developing a new edition of IEC 60880 included the need to align with rapidly evolving software engineering techniques during the past 10 years," said SC45A Secretary Jean-Paul Bouard.

The original standard was published in 1986 and was the first to give recommendations for the use of software in nuclear safety systems. The new edition describes each stage of software generation and documentation including requirements specification, design, implementation, verification, validation and operation.

The publication details the principles and basic safety aspects that pertain to the safety of nuclear power plants provided in the International Atomic Energy Agency (IAEA) code and safety series. The terminology and definitions used in the new standard are consistent with those used by the IAEA.
