Analysis of differences between international and Swedish reporting of events at nuclear power plants (English)
Abstract [en]

Report of diploma work conducted at the Swedish Radiation Safety Authority (SSM) as part of the bachelors program in Nuclear Engineering at Uppsala University.

All nuclear power plants in Sweden are obliged to report any deficiency in their barriers or the defense in depth in obedience to SSM’s regulations concerning safety in nuclear facilities. In addition, there is an international system for reporting such events. The purpose of this thesis is to study the Swedish report system and to analyze the differences between Swedish and international event reporting.

In the Swedish system, SSM’s regulations are effectuated by means of event reports classified as category 1-3, designed individually at each Swedish facility. Accordingly, the reporting differs somewhat between facilities. The number of reports in the Swedish system is relatively large, with a frequency of about 400 per year.

Internationally, a system called the International Reporting System for Operating Experience (IRS) has been developed, through which the participating countries exchange experience to improve the safety of nuclear power plants. The IRS reporting frequency is about 100 per year in total, and Sweden contributes to IRS with 1-2 reports per year.

This report accounts for a comparison of the two report systems, including some differences and similarities that have been identified. The result shows that the Swedish system covers IRS well but does not have the same comprehensive classification of events and the same standardized format of reporting as the IRS system. The conclusion is that some improvements may be made to the Swedish system, which would facilitate the international exchange of experience at the Swedish nuclear power plants.
