HRA requirements for PRAs

The purpose of this paper is to produce some discussion about the current trends in the nuclear power industry as far as human reliability assessment methods and approaches are concerned including the skills and knowledge of industry HRA specialists. The paper addresses topics covered in the withdrawn IEEE standard P.1547, “Recommended Practice for Conducting Human Reliability Analysis for Nuclear Power Generating Stations.” The choice of HRA methods is discussed along with the skills needed for utility HRA specialists and the various sources of HRA data. The IEEE standard introduced three categories similar to the premier PRA standard generated by the ASME. The paper discusses these and calls for a critical discussion into the relationship of HRA models, data, experts and HRA practitioners to categories in PRA/HRAs.
