The U.S. Nuclear Regulatory Commission (NRC) Office of Nuclear Regulatory Research (RES) and the Electric Power Research Institute (EPRI) conducted a joint public meeting consisting of a fire PRA (Probabilistic Risk Assessment) course on September 27 – October 1 and October 25 - 29, 2010 at the Legacy Hotel and Conference Centre in Rockville, MD. The purpose of the course was to provide detailed, hands-on training on the fire PRA methodology described in the technical document, NUREG/CR-6850 (EPRI 1011989) entitled “EPRI/NRC-RES Fire PRA Methodology for Nuclear Power Facilities.” This fire PRA methodology document supports implementation of the risk-informed, performance-based rule 10CFR50.48(c) endorsing National Fire Protection Association (NFPA) Standard 805, as well as other applications such as exemptions or deviations to our current regulations and fire protection Significance Determination Process phase 3 applications.
RES and EPRI provided training in four subject areas: Fire Analysis, PRA, Human Reliability Analysis (HRA) and Electrical Analysis. Participants selected one of these subject areas and spent the duration of the course in the module that covered the subject area that they selected. 2010 was the first year that a separate HRA module was included in the course. It covered the newly developed HRA guidance provided in draft NUREG-1921, “EPRI/NRC-RES Fire Human Reliability Analysis Guidelines.” This volume and its accompanying DVD contain the materials presented in the HRA module.
The material in this NUREG/CP was recorded at the workshops conducted in 2010, and adapted by RES Fire Research Branch members for use as an alternative training method for those who were unable to physically attend the training sessions. This report can also serve as a refresher for those who attended one or more training sessions and would be useful preparatory material for those planning to attend a session.
