Manual for IRS Coding. 2022 Edition. Joint IAEA and OECD/NEA International Reporting System for Operating Experience (IRS)

The fundamental objective of the International Reporting System for Operating Experience (IRS) is to contribute to improving the safety of commercial nuclear power plants worldwide. This objective can be achieved by providing timely and detailed information on lessons learned from designing, constructing, commissioning, operating and decommissioning experiences at the international level. Such information relates to all issues and events that are relevant to nuclear safety. In 2010 the IAEA and the Nuclear Energy Agency of the Organisation for Economic Co-operation and Development (OECD/NEA) published IRS Guidelines (IAEA Services Series No. 19), which was revised in 2022 (IAEA Services Series No. 19 (Rev. 1)). In 2011 the IAEA and the OECD/NEA published the Manual for IRS Coding (IAEA Services Series No. 20). This revised publication is intended as a companion to IRS Guidelines and supersedes all previous versions. It describes the individual coding fields in detail and their proper application in the preparation of IRS reports. This publication is the outcome of consultancy meetings held in Vienna in May 2019 and November 2019. It is closely aligned with IAEA Safety Standards Series No. SSG-50, Operating Experience Feedback for Nuclear Installations.
