1. INTRODUCTION

101. The evaluation of the safety features of nuclear power plants and the preparation 
of operating procedures for abnormal conditions are based on accident analysis, 
which uses complex methodologies. Nuclear power plant operational experience is 
therefore essential for testing the assumptions used in the analysis and for improving 
nuclear safety.

102. The conduct of operations itself is also an important component of the overall 
safety, including the experience gained from day to day surveillance and maintenance 
activities carried out on equipment, and personnel or administrative matters.

103. For all these reasons, a proper analysis of unusual events can identify root 
causes, provide valuable lessons to be learned and lead to improvements in the 
operational safety of nuclear power plants. For this purpose it is extremely important 
to collect information on unusual events with safety significance occurring at plants 
during operations, surveillance and maintenance activities, including deviations from 
the normal performance of systems, or personnel errors which may be precursors of 
serious accidents.
