> NRC Meeting, January 30, 2018 4 OP-100 Package 10-gal Carbon Steel Standard Drum Overpack

• Two Drum Versions14.0 inch x171/2 inch high, DOT/UN 1A2/X150/S (Steel IAW Obsoleted ASTM A366 Standard)14.0 inch x18.9 inch high, DOT/UN 1A2/X120/S (Steel IAW Current ASTM A1008/A1008M Standard)Payload Support Structures

• 3/4-inch Thick Plywood Interlocking Panels & 2 x4 Wood Insert Supports (Original)

• 4 lb/ft 3Polyurethane Foam Surround (Amendment)

> NRC Meeting, January 30, 2018 5 OP-100 Package (con't)Two Support Structures: Foam (Left), Plywood (Right)

> NRC Meeting, January 30, 2018 7 Payload DescriptionsCurrently Authorized Payloads

• IR-100 Exposure Device

• IR-50 Source Changer Additional Payload

• IR-100ST Exposure Device

• Modified IR-100 Exposure Device Fitted w/ Tracking Device as Recommended by NNSA/GTRI Task ForceSpecial Form Radioactive Material Limit

> NRC Meeting, January 30, 2018 9 OP-100 PackageApproach to Respond to NRC RAIsRAI 2-1, Material Properties

• Clarify Referenced ASTM Material Standards in SAR ASTM A366, which was obsoleted in August 2000, applies to older existing drums currently in useASTM A1008, which replaced A366, applies to new

drums ASTM A568, which is a standard for steel mill production and has no material properties, to be

removed.*Drum manufacturer selects material grade CRCQ carbon steel per ASTM A1008 that meets their self-certified DOT/UN rating, i.e., DOT/UN 1A2/X120/S

• Drum utilized for OP-100 package specified by DOT/UN

rating only

> NRC Meeting, January 30, 2018 10 OP-100 PackageApproach to Respond to NRC RAIs (con't)RAI 2-2, Polyurethane Foam Support Structure Justification for Bounding Payload Damage

• Original free and puncture drop tests were not instrumented for impact forces

• No analytical basis can be performed to demonstrate foam structure is bounded by plywood structure

• Free drop tests to be performed with foam support

structure*Selected drop orientations based on impact damage from original free drops

> NRC Meeting, January 30, 2018 11 OP-100 PackageApproach to Respond to NRC RAIs (con't)CTU-2 (IR-100) Side Drop Damaged Lock Box

> NRC Meeting, January 30, 2018 12 OP-100 PackageApproach to Respond to NRC RAIs (con't)CTU-3 (IR-100) Side Drop Damaged Lock Box

> NRC Meeting, January 30, 2018 13 OP-100 PackageApproach to Respond to NRC RAIs (con't) CTU-4 (IR-50) CG-Over Corner Drop Damage

> NRC Meeting, January 30, 2018 14 OP-100 PackageApproach to Respond to NRC RAIs (con't) Conclusions from Original Free Drop Tests:

• Lock Box Damage May Occur When Minimum Clearance Exists Between Device and Drum Wall

• Maximum Deformation to Support Structure & Drum Occurs for Top Down, CG-Over-Corner OrientationPolyurethane Foam Support Structure

• Minimum Clearance is 2.7 Inches with IR-50 Device

• Selected Orientations for Free Drops Bottom Down w/ IR-50 Source ChangerTop Down, CG-Over-Corner w/ IR-50 Source Changer

• Single CTU to be tested at ~100 °F (NCT Hot Condition) to Maximize Deformation
