Investigation of reactor incident reports with regard to human malfunctions as far as these had an effect on the incident history

The study has the aim to examine by means of a human failure analysis the operation of a nuclear power plant with regard to its weak points, in order to deduce by this starting-points for operational improvements. Contrary to most studies published on this subject and which are often based on free-hand hypotheses and plausibility studies here, the experience gained in the operation is systematically examined with regard to human malfunction and their deeper causes, i.e. on the experience which was founded on some 1,000 collected reports on incidents.
