NUREG-1842, “Evaluation of Human Reliability Analysis Methods Against Good Practices, Draft Report for Comment, Draft for Comment”

The NRC is developing guidance for performing or evaluating human reliability analyses (HRAs) to support risk-informed regulatory decision-making and, in particular, the implementation of Regulatory Guide 1.200, “An Approach for Determining the Technical Adequacy of Probabilistic Risk Assessment Results for Risk-Informed Activities,” dated February 2004. The guidance is developed in two phases. The first phase focused on developing “Good Practices for Implementing Human Reliability Analysis,” that is documenting the processes and analytical tasks and judgments expected to have been performed in order for the HRA results to sufficiently represent the anticipated operator performance in risk-informed decisions. The good practices were submitted for public comment, NUREG-1792, Good Practices for Implementing Human Reliability Analysis, Draft Report for Comment,” August 2004, and were published as a final NUREG-1792 in April 2005. The second phase, summarized in draft NUREG-1842, evaluated the various HRA methods that are commonly used in regulatory applications, with a particular focus on their capabilities to satisfy the good practices, as well as their respective strengths and limitations regarding their underlying knowledge and data bases.

The NRC is seeking public comment in order to receive feedback from the widest range of interested parties and to ensure that all information relevant to developing this document is available to the NRC staff. This document is issued for comment only and is not intended for interim use. The NRC will review public comments received on the document, incorporate suggested changes as necessary, and issue the final NUREG-1842 for use.

The NRC will hold a public meeting on May 23, 2006 at the NRC headquarters, 11545 Rockville Pike, Rockville, Maryland, Room: Commission Briefing Room (8:30 a.m.-5 p.m., preliminary agenda enclosed). The purpose of the meeting is to discuss the findings and conclusions documented in NUREG-1842 in order to allow stakeholders develop a better understanding of the contents of the report and ask clarification questions. The NRC is not soliciting comments on draft NUREG-1842 as part of this meeting. Public comments on the draft NUREG can be provided as discussed above.
