Technical Meeting for National Coordinators of the International Reporting System for Operating Experience on Recent Events at Nuclear Power Plants

Background

The International Reporting System for Operating Experience (IRS), operated jointly by the International Atomic Energy Agency (IAEA) and the Nuclear Energy Agency of the Organisation for Economic Co-operation and Development (OECD/NEA), compiles and analyses information on nuclear power plant (NPP) events and promotes a systematic approach to the feedback of lessons learned from operating experience.
