Natural Phenomena Hazards NRC/DOE October 2022 What We Can Learn from the Open, Collaborative NGL Case History Database K. Ulmer1, T. Weaver2, J. Stamatakos1, and M. Juckett1 1

U.S. Nuclear Regulatory Commission During the last seven years, staff at Southwest Research Institute (SwRI) have been working with staffs from the U.S. Nuclear Regulatory Commission (NRC) and the Bureau of Reclamation (USBR) to develop probabilistic technical bases that are needed to update regulatory guidance on liquefaction hazards. As part of this work, we have collaborated with the Next Generation Liquefaction (NGL) project to develop an extensive database of liquefaction case histories (nextgenerationliquefaction.org). In this presentation, we highlight the usefulness of the NGL database, particularly for applications relevant to the nuclear industry and seismic hazard reduction. The NGL database provides an accessible, objective, digital, expert-reviewed, and consistently formatted catalog of case history data that facilitates and supports research aimed at mitigating liquefaction hazard. We share several examples of queries that are possible through the databases graphical user interface (GUI) and examples of sophisticated, automated workflows enabled through connecting directly to the NGL database through Jupyter notebooks in DesignSafes cyberinfrastructure (designsafe-ci.org). Some examples include summarizing and downloading case histories that match a set of criteria, performing complex computations related to liquefaction analyses, developing correlations between in situ measurements, and using visualization tools for data trends and data synthesis from other digital sources outside NGL. Finally, we summarize our current research efforts in coordination with the NGL project and identify areas of future work that will help modernize liquefaction hazard analyses for applications in the commercial nuclear industry.
