Publication InformationManuscript Completed: September 2007 Edited by Idaho National Laboratory Science Applications International Corporation E. Lois, NRC Project Manager NRC Job Code Y6496 Office of Nuclear Regulatory Research AbstractThe U.S. Nuclear Regulatory Commission (NRC) is addressing issues related to the quality of Probabilistic Risk Assessment (PRA), including issues related to human reliability analysis (HRA) performed as part of PRA. Among the issues of concern is an inadequate use of human performance data in the estimation of human error probabilities (HEPs), as well as in testing or otherwise validating underlying models used in HRA to predict human performance under cognitively demanding conditions. In order to address issues related to the use of human performance data in HRA, the NRC is developing the Human Event Repository and Analysis (HERA) database (NUREG/CR-6903). In addition, in August 2005, the NRC hosted an expert workshop on the use of Bayesian and other quantitative formalisms in conjunction with empirical data, such as that available in HERA, to improve both the estimation of human error probabilities and the underlying assumptions and quantitative algorithms employed by different HRA methods. This report contains a collection of papers that were produced as a result of the workshop. It also summarizes the peer review comments of a draft version of this report, includes conclusions about the feasibility of using empirical data and quantitative methods for HRA, and provides suggestions on how to proceed to address the issues under consideration. Paperwork Reduction Act Statement This NUREG does not contain information collection requirements and, therefore, is not subject to the requirements of the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.). Public Protection Notification The NRC may not conduct or sponsor, and a person is not required to respond to, a request for information or an information collection requirement unless the requesting document displays a currently valid OMB control number. |
