Guidelines for condensed documentation of a probabilistic risk assessment. Final report
- Electricite de France, Clamart (France)
A desire to ``codify`` practices for the preparation and use of Probabilistic Risk Assessments (PRAs) is emerging in France. EDF has set itself the objective of developing PRAs that are representative of each nuclear power plant series in operation, that will produce standard results (core damage frequency, ranking of risk components, etc.), that meet the requirements of applications, and that use common tools. As PRA applications develop, it becomes even more important to ensure a consistent documentation of the PRA models for the application at hand. An important issue here is the turnover of engineers at utilities. As engineers move in and out of the utility or even the PRA group, the memory of the hidden assumptions in the PRA models must be captured reliably. That is, it must be captured in a framework that allows easy retrieval by staff who may never have participated in the original development. Condensed documentation of the main strategic choices and technical assumptions greatly facilitates the appropriation of PRA models and their use for applications. The purpose of this report is to outline four sections of the PRA condensed documentation (Sequence Development, System Analysis, Component Reliability data, Initiating Events). Each section is illustrated in its companion appendix.
