Report Title:
Nordic studies in reactor safety
Activity Acronym:
SIK
Authors:

Abstract:
The SIK programme in reactor safety is part of a major joint Nordic
research effort in nuclear safety. The report summarizes the
achievements of the SIK programme, which was carried out during
1990-1993 in collaboration between Nordic nuclear utilities, safety
authorities, and research institutes. Three main projects were
successfully completed dealing with:
(1) development and application of a living PSA concept for monitoring
the risk of core damage, and of safety indicators for early warning of
possible safety problems;
(2) review and intercomparison of severe accident codes, case studies of
potential core melt accidents in Nordic reactors, development of
chemical models for the MAAP code, and outline of a system for
computerized accident management support;
(3) compilation of information about design and safety features of
neighbouring reactors in Germany, Lithuania and Russia, and of
naval reactors and nuclear submarines.
The report reviews the state-of-the-art in each subject matter as an
introduction to the individual project summaries. The main findings of
each project are highlighted. The report also contains an overview of
reactor safety research in the Nordic countries and a summary of
fundamental reactor safety principles.
