Review of Preparedness for Severe Natural Phenomena Events at the Lawrence Livermore National Laboratory

The Office of Enforcement and Oversight (Independent Oversight), within the Office of Health, Safety and Security (HSS), conducted an independent review of the National Nuclear Security Administration (NNSA) Livermore Field Office (LFO) and Lawrence Livermore National Laboratory (LLNL) Site 200 preparedness for severe natural phenomena events (NPEs). The HSS Office of Safety and Emergency Management Evaluations performed this review to evaluate the processes for identifying emergency response capabilities and maintaining them in a state of readiness in case of a severe NPE. This report discusses the scope, background, methodology, results, and conclusions of the review, and identifies six findings and several opportunities for improvement (OFIs).
