Overhead Vertical Strike Analysis for the MCOs in the CSB.

DE2003805642

Publication Date	2000
Personal Author	Packer, M. J.
Page Count	11
Abstract	The purpose of this calculation is to document the structural adequacy of Multi-Canister Overpacks (MCOs) in two separate normal configurations for the 40-year interim period in the storage tubes at the Canister Storage Building (CSB). The two configurations apply when the lower MCO is arranged with (1) just a shield plug mechanical closure or (2) with the canister cover welded over the shield plug. Multiple analyses have been conducted to show the MCO design is adequate for drop events involving a lower, passive MCO being struck by an overhead drop load MCO both in vertical position. Minimal plastic deformations are experienced for either the MCO with shield plug or the MCO with cover cap. This survivability at 35 g's demonstrates the package's worthiness for 40 years of storage.
