Incident reporting has become an increasingly important aspect of the operation and regulation of all public health and safety-related industries. Diverse industries such as aeronautics, chemicals, pharmaceuticals and explosives all depend on operating experience to provide lessons learnt about safety.

The Incident Reporting System (IRS) is an essential element of the system for feeding back international operating experience for nuclear power plants. IRS reports contain information on events of safety significance with important lessons learnt. These experiences assist in reducing or eliminating recurrence of events at other plants. The IRS is jointly operated and managed by the Nuclear Energy Agency and the International Atomic Energy Agency (IAEA).

The first report, which covered the period July 1996-June 1999, was widely acclaimed and encouraged both agencies to prepare this second report in order to highlight important lessons learnt from around 300 events reported to the IRS for the period July 1999-December 2002. Several areas were selected in this report to show the range of important topics available in the IRS. These include different types of failure in a variety of plant systems, as well as human performance considerations.

This report is primarily aimed at senior officials in industry and government who have decision-making roles in the nuclear power industry.
