- 1. GENERAL INFORMATION 1.1 Introduction The Versa-Pac is a drum type package that features a patented [1] design concept in combination with the familiar drum exterior packaging to provide enhanced structural protection to payloads during the Normal Conditions of Transport (NCT) and Hypothetical Accident Conditions (HAC)
[2]. Principal design of the Versa-Pac packaging maintains the use of an inner container positioned inside a 55-gallon (VP-55) or 110-gallon drum (VP-110). The Versa-Pac is used directly or in conjunction with pails, pipe containers, poly bottles, and a variety of smaller containers, inserts and vessels. The Versa-Pac standard configuration shipping packages, model numbers VP-55 and VP-110, have been designed to transport Type A fissile materials limited to U-235 masses based on the loading limits in Table 1-1.

Docket No. 71-9342 Versa-Pac Safety Analysis Report Rev 10, March 2018 1-3 1.2 Package Description 1.2.1 Packaging Engineering Drawings are provided in Appendix 1.4.1. General notes pertaining to fabrication are provided in Appendix 1.4.2. An illustration of the packaging configuration is provided in Figure 1-
- 1. Packaging markings are shown on the drawings in Appendix 1.4.1.
The exterior skin of the Versa-Pac consists of at a minimum, a UN1A2/Y425/S for the VP-55. The drums use a bolted closure ring, standard carbon steel lugs, 5/8 diameter, ASTM (American Society for Testing Materials) A429 bolts and nuts, and a closed-cell rubber lid gasket. The overall outer dimensions of the 55-gallon drum are 23-3/16 OD x 34-3/4 in height to the top of the outer drum bolt ring. The drum cover is reinforced by a 10-gauge thick 22-3/8 OD x 18-3/8 ID plate, and four 1/2 bolts are provided to lend additional strength to the drum closure ring.
The VP-110 utilizes at a minimum a UN/1A2/Y409/S. The drums use a bolted closure ring, standard carbon steel lugs, 5/8 diameter ASTM A429 bolts and nuts, and a closed-cell lid rubber gasket. The overall outer dimensions for the 110-gallon drum are 30-7/16 OD x 42-3/4 in height to the top of the outer drum bolt ring. The drum cover is reinforced by a 10-gauge thick 29-3/4 OD x 27-1/4 ID plate and eight 1/2 bolts are provided to lend additional strength to the drum closure ring.
Both drums are further strengthened with vertical stiffeners fabricated from 1-1/4 carbon steel square tubing, two inner liners of rolled 16-gauge carbon steel insulated by ceramic fiber blanket encase the vertical tubing, and a 1/4 carbon steel reinforcing plate on the bottom.
The packages inner container is completely insulated with the appropriate layers of ceramic fiber blanket around the containment area with rigid polyurethane foam disk on the top and on the bottom to complete the insulation of the package. Specifications for the insulation are provided in Appendices 1.4.3 for the polyurethane foam and 1.4.4 for the ceramic fiber blanket. The primary function of both insulations is to provide thermal protection. Although the rigid polyurethane provides some impact protection, the frame of the packaging performs the majority of the required impact protection.
A 1/2 thick fiberglass ring is used as a thermal break at the payload cavity flange. The thermal break is sandwiched between the steel components, with twelve 1/2-inch bolts providing the connection between the structural members through the fiberglass and effectively limits the flow of heat to the payload cavity through the steel flange components. There are no moving parts to the thermal break, and its functionality is maintained as long as it separates the steel components FB, top stiffening ring, from FK, connection ring, (See Drawings in Appendix 1.4.1). A specification for the fiberglass material is provided in Appendix 1.4.5.
The containment boundary of the package is defined as the payload vessel with its associated welds, payload vessel high temperature heat resistant silicone coated fiberglass gasket, payload vessel blind flanges, and reinforcing ring.
The payload vessel is comprised of a 10-gauge carbon steel sheet for the body and bottom. The upper end of the vessel is fitted with a 1/4 inner carbon steel flange ring with a 1/2-thick carbon steel blind flange. The vessel has three circumferential welds (two at the flange, one at the base) and one longitudinal weld. A 1/8 high temperature heat resistant silicone coated fiberglass gasket is used between the steel flange ring and blind flange. The payload vessel blind flange is secured
Docket No. 71-9342 Versa-Pac Safety Analysis Report Rev 10, March 2018 1-4 with twelve 1/2 bolts. There are no penetrations, valves or venting devices used within the containment boundary.
The Versa-Pac meets the General Requirements for all packages as specified in 10CFR71.43
[3].
1.2.1.1 Gross Weights The gross weights of the two Versa-Pac models are 750 pounds for the VP-55 and 965 pounds for the VP-110, see Section 2.1.3.
1.2.1.2 Materials of Construction The materials of construction of the Versa-Pac are provided in the Licensing Drawings parts list presented in Appendix 1.4.1.
1.2.1.3 Outer and Inner Protrusions There is one outer protrusion on the Versa-Pac consisting of carbon steel fitting which contains a 1 plastic plug on the side of the package. The plug is designed to melt and allow venting of any gases that might develop in the event of a fire. The protrusion extends less than 1/2 from the sidewall of the outer drum and does not impede the stacking or handling of the shipping package.
There are no inner protrusions on the Versa-Pac.
1.2.1.4 Lifting and Tie-Down Devices The Versa-Pac may be handled by normal industry standards for the safe movement of drums; such equipment might include specifically designed devices, forklifts, pallet jacks or other methods as determined by the User. However, the Versa-Pac does not utilize any specific device or attachment for lifting. Additionally, there are no specific provisions for tie down of the package.
1.2.1.5 Shielding Neutron and gamma shields are not required for the Versa-Pac payloads.
1.2.1.6 Pressure Relief Systems There are no pressure relief systems other than the four 1/4 holes, closed with vinyl push plugs on the inner liner between the insulation and containment and one in the top cavity area used to vent gases that might be produced in the event of a fire. No special heat transfer mechanisms are provided or required.
1.2.1.7 Containment Features There are three individual points of closure employed by the Versa-Pac. The payload 1/2-inch-thick closure plate provides a fastening and seal using twelve 1/2 bolts and a 1/8-thick silicone coated fiberglass gasket. A second closure is provided at the outer drum lid. The drum lid is secured using 1/2 bolts and is sealed with a 3/8-thick silicone rubber flat gasket. A standard drum ring, its rubber gasket, and a 5/8 tensioning bolt provide the final closure. A 1/8 hole is drilled in the end of the tensioning bolt for use with a security seal.
The primary containment boundary of the Versa-Pac is defined as the inner containment body, containment end plate, inner flange ring, silicone coated fiberglass gasket, 1/2 blind flange, 1/2
Docket No. 71-9342 Versa-Pac Safety Analysis Report Rev 10, March 2018 1-5 bolts, washers and insert holders. Figure 1-1 further illustrates these components by text description enclosed within a text box.
1.2.1.8 Package Markings Package marking are shown in Appendix 1.4.1 and 1.4.2.
1.2.2 Contents All materials must be in solid form with no freestanding liquids; density is not limited. These material quantities may not exceed the U-235 limits established in Table 1-1 in any non-pyrophoric form. Materials that may be shipped in the Versa-Pac include uranium oxides (UyOx), uranium metal (U-metal), uranyl nitrate crystals (UNX), and other uranium compounds (e.g., Uranyl Fluorides and Uranyl Carbonates). The uranium compounds may also contain carbon or graphite (e.g., UC, U2C3 and UC2). UNX may be in the form of uranyl nitrate hexahydrate, trihydrate or dihydrate, and must be in solid form. The payload may be in homogeneous (powder or crystalline) or non-homogeneous form. The contents are limited to Type A, normal form material per 10CFR71 [3].
The Versa-Pac is evaluated assuming optimum moderation using a bounding high-density polyethylene plastic (Density = 0.98 g/cc) and supports packaging applications containing both carbon (e.g., graphite, paraffin, and polyethylene) and hydrogen based materials (e.g., water paraffin, and polyethylene). Non-fissile chemical impurities do not increase the reactivity of the system; therefore, they may be present in any quantity. The payload may be enriched in U-235 to 100 wt.% while maintaining the limits in Table 1-1. Because the payload decay is essentially zero (approximately 11.4 W, Section 3.4.2), there are no radiolytic decay products.
When using the 5-inch pipe configuration, all fissile contents must be loaded into a single 5-inch pipe and sealed per the instructions in Section 7. The fissile quantity for this configuration shall meet the limits in Table 1-1A.
Additional contents include uranium hexafluoride (UF6) in ANSI N14.1 compliant 1s and 2s cylinders. For any shipments of 1S and 2S cylinders, a foam insert (9 PCF polyethylene) shall be used to provide thermal protection for the cylinder. The minimum foam insert thickness shall be 2 inches, circumferentially between the 1S/2S cylinders and the cavity wall of the Versa-Pac.
Cribbing or dunnage may be used inside the foam insert to restrict movement of the contents during transport, providing a snug fit for the 1S/2S cylinders or multiple 5-inch pipes. The fissile quantity of material in any shipment of 1S/2S cylinders must meet one of the following requirements:
- 1. The number of cylinders in a single package shall meet the limitations in Table 1-1B, or Table 1-1C when each cylinder is packaged into a separate 5-inch pipe. For this case, either 1S or 2S cylinders may be loaded into a single package (i.e., no mixing of cylinder types).
- 2. The total fissile mass (in grams of U-235) from all cylinders shall meet the limits set in Table 1-1. For this case, any number or combination of 1S and 2S cylinders is acceptable, so long as the U-235 mass limit is not exceeded. The U-235 mass limit for this case is established based on the cylinder with the highest enrichment (e.g. for two cylinders with enrichments of 5 wt.% and 15 wt.%, respectively, the U-235 mass limit is based on the 20 wt.% limit).
Docket No. 71-9342 Versa-Pac Safety Analysis Report Rev 10, March 2018 1-6 The payload material may be pre-packaged in hydrogenous or non-hydrogenous containers within the payload vessel. Hydrogenous pre-packaging materials may include polyethylene, polypropylene, and PVC (polyvinyl chloride). PTFE (Polytetrafluoroethylene) or Teflon pre-packaging material is also allowed. Metallic pre-packaging materials such as aluminum, stainless and carbon steel are allowed. Table 1-5 provides a listing of typical packaging materials used to pack the Versa-Pac.
Package contents are typically shipped in an axial array to fill the payload cavity. A fireproof perlite like packing material is often used as dunnage to fill the voids between the cans and inner vessel wall. The Versa-Pac design allows for the use of two neoprene pads, a 1/8-inch bottom pad, and a 3/8-inch top pad. The pads serve the purpose of protecting the inner containment shell during repeated use. The use of these pads is optional for packages not intended for reuse.
No materials, excluding the minimum steel wall thickness of the package, are used as neutron absorbers or moderators.
The maximum payload capacity for the VP-55 is 350 pounds. The maximum payload capacity for the VP-110 is 260 pounds.
1.2.3 Special Requirements for Plutonium The Versa-Pac is not approved for the transport of Plutonium above minimum detectable quantities.
1.2.4 Operational Features The Versa-Pac provides for two individual closures and seals to secure the payload within the inner containment area. Connections and closures are accomplished using bolt and gasket seals.
There are no operationally complex features of the Versa-Pac. All operational features are readily apparent from an inspection of the drawings provided in Appendix 1.4.1, Packaging General Arrangement Drawings. Operation procedures and instructions for loading, unloading, and preparing an empty Versa-Pac for transport are provided in Chapter 7.0, Operating Procedures.

Versa-Pac Safety Analysis Report Docket No. 71-9342 Rev 10, November 2018 1-21 1.4.6 Versa Pac VP-55 5-inch Pipe 1.4.6.1 VP-55 with 5-inch Pipe Packaging Description The 5-inch pipe container fits inside the VP-55 payload vessel. The payload vessel is described in Section 1.2.1. Licensing Drawings are provided in Section 1.4.1.
The 5-inch pipe container is fabricated from Schedule-40 carbon steel. There is a carbon steel plate welded to the bottom. The top is closed with a 5-inch threaded cap made from malleable iron. The pipe container is held in place during routine transport by a birdcage device that provides no structural support. It is considered dunnage. No credit is taken for the pipe maintaining a specific position within the payload cavity under non-routine conditions.
Handling instructions for the VP-55 5-inch Pipe are provided in Section 7.1.1. When utilized in the VP-55, the 5-inch pipe is simply used for geometric confinement of the fissile material in the contents. Although all radioactive material is confined inside the pipe during all transport conditions, the containment boundary of the package is always the inner vessel of the Versa-Pac package. The 5-inch pipe, contents, and any additional dunnage/cribbing are accounted for as the total content weight in the determination of the maximum payload weight for the VP-55 package (see Section 2.1.3).
1.4.6.2 VP-55 with 5-inch Pipe Contents The 5-inch pipe container and any additional dunnage/cribbing are considered contents of the VP-55 package in this configuration. All radioactive contents are loaded directly into the 5-inch pipe when shipping in this configuration. The material requirements for the 5-inch pipe configuration are identical to the standard VP-55 requirements. The fissile material limits for the VP-55 with 5-inch pipe configuration are provided in Table 1-1A and Table 1-1C.
