Structural Screening and Evaluation.
3.3
3.3.1
Structural Screening. Structural screening consists of simplified but conservative
structural evaluation of the facility using two bounding missiles, one for building
local damage evaluation and the other for building collapse evaluation
(Section 6.2). If this evaluation indicates that the building components meet the
structural screening guidelines (Section 4.3) for all impact locations and if there is
no safety-related equipment supported from the building structure in the vicinity of
the postulated impact, the risk is deemed small and the results are documented. If
the guidelines are exceeded for any impact location or if there is any safety-related
