The International Reporting System for Operating Experience (IRS) is an international system through which thirty-three participating countries exchange experience to improve the safety of nuclear power plants by submitting event reports on unusual events considered important for safety.
The aim of the IRS is to increase the effectiveness in analysing and communicating operational safety experience.
The IRS is for use, within each participating country, by organizations professionally involved in the nuclear industry, such as: regulators, utilities, NPP staff, technical support, vendor companies (design firms, engineering contractors, manufacturers, etc.), research establishments or technical universities working in the nuclear field.
