Spec. No. N/A Addendum #1 8/28/78 5/9/79 - Revision 1 INTRODUCTION This addendum to the Safety Analysis Report for the Ilittman Nuclear & Development Corporation IIN-100, Series 2 Radwaste Ship-ping Cask is issued to remove the restriction requiring Type "A" inner containers. This addendum addresses the lid seal integrity during the calculated free drop. The following calculations are intended to be a supplement to Section 3.2.6 of the original Safety Analysis Report. 2247 208 123so
Spec. No. N/A Addendum #1 8/28/78 5/9/79 - Revision 1 Cask HN-100, Series 2, Stress Analysis Gasket Spacer The gasket redesign requires a protective steel spacer. The spacer is in the form of a ring and is welded to the top of the case where the lid interfaces with the case. See Figure R-1. The lid compresses the gasket and bottoms on the spacer.

Position of Cask at Edge Drop The drop height o f 12" and a gross weight of 48,.000# yields a kinetic energy KE = (12)(48000) = 570,000#-in. The flow stress is 45,000#, giving a displacement V o f. 57G,000 V= 45,000 = 12.8 in.3 The volume displaced is in the shape of a prism with a triangular cross section of the length L of the edge.

Item 2.1.1 Drain plug Option IIN-100 Se ri es 2 casks have two (2) possible drain plug configura- { tions. Option #1 detai.ls the drain plug being inserted at an angle to the horizontal plane of the cask bottom and positioned between the tie-down support axis. Option #2 shows the drain plug enter-ing horizontal to the cask bottom with a double plug con figuration. This second option locates the drain plug app rox ima t e ly 90 from Option #1. The Option #2 con figuration enhances the ability to drain the cask with minimum operational exposure. 2247 211 rg350 A-3}}
