N2 - For risk management, the results of a probabilistic
risk analysis (PRA) as well as the underlying assumptions can
be used as references in a closed-loop risk control; and the
analyses of operational experiences as a means of feedback. In
this context, the need for explicit definition and documentation of the PRA coverage, including the search strategies
applied, is discussed and aids are proposed such as plant
description in terms of a formal abstraction hierarchy and use
of cause-consequence-charts for the documentation of not only
the results of PRA but also of its coverage. Typical human risk
contributions are described on the basis of general plant
design features relevant for risk and accident analysis.
With this background, search strategies for human risk contributions are treated: Under the designation "work analysis",
procedures for the analysis of familiar, well trained, planned
tasks are proposed. Strategies for identifying human risk
contributions outside this category are outlined.
