A review of historical data from real-world seismic events at nuclear power plants and other industrial facilities was performed in order to identify potential failure modes and performance shaping factors (PSFs) that should be considered when developing the human reliability analysis (HRA). The results of this review are published in EPRI 1025294, A Preliminary Approach to Human Reliability Analysis for External Events with a Focus on Seismic. The operating experience review task primarily built upon previous, published work conducted by EPRI (Post-Earthquake Investigation Program from 1985 to 2012), as well as a review of utility presentations and LERs; interviews were conducted with personnel from nuclear plants impacted by recent seismic events. The majority of the operating experience supports the insight that operator actions during both high and low magnitude seismic events tend to be highly reliable, even in the short time frame (e.g., first 10 minutes). There are some specific lessons to be learned from nuclear and non-nuclear experience regarding possible weaknesses in the response capabilities. This paper provides a summary of insights from this review of nuclear and non-nuclear power plant operating experience during seismic events, along with a summary of how these relevant lessons are incorporated into the guidance for the various steps of the HRA process described in EPRI 1025294. A separate, but related, paper titled "A Preliminary Approach to Human Reliability Analysis for External Events with a Focus on Seismic" has also been submitted to this conference to describe the development of the EPRI Seismic HRA method in EPRI 1025294.
