Walkdowns and Field Verification
Plant walkdowns are physical inspections that translate analytical assumptions into verified site conditions. In external hazard assessment, walkdowns confirm which structures, systems, and components are exposed to a given hazard, characterize the hazard sources and physical layout on site, and identify conditions that may differ from design-basis assumptions. The High-Wind Equipment List procedure in EPRI 3002008092, for example, is a formalized walkdown process for high winds including the identification of potential missile populations.
