Abstract
EXAM-HRA is an international project which assesses human
reliability analysis (HRA) applications in existing
probabilistic safety analysis (PSA) studies. The overall
project objective is to provide guidance for a "Good
praxis" HRA for purposes of PSA to ensure that plant
specific properties are properly taken into consideration
in the analysis and to provide means to improve plant
features based on HRA results. This includes identifying
discrepancies and actual aspects explaining why
differences in results can be observed in HRA
applications. The guidance developed in the project shall
also provide means to improve the experience feedback on
plant features based on HRA and PSA results.
The project has been performed in several consecutive
phases. In the first phase a framework for identifying
discrepancies in existing HRA applications was developed.
This included development of a survey and screening
process for operator actions in existing PSA studies as
well as development of an evaluation guide. The survey
provided an overview of performed HRA applications in
Nordic and German PSAs, including approximately 420
operator actions from six PSA studies, and constituted
the basis for the selection of scenarios and actions for
assessment in the upcoming phases. The case studies
resulted in observations that allow for improvements of
both plant features as well as the HRA itself. In the
current stage, the collaboration has been expanded to
cover also Swiss and French partners.
The paper presents the EXAM-HRA analysis framework and
major findings so far.
