Canadian Certificate No.: CDN/2094/B(U)-96 (Rev. 4)
Issue Date: Sep-20-2021 Expiry Date: Mar-31-2025 CNSC File: 30-A2-247-0 Certificate CDN/2094/B(U)-96 (Rev. 4)
Transport Package Design The transport package design identified below is certified by the Canadian Nuclear Safety Commission pursuant to paragraph 21(1)(h) of the Nuclear Safety and Control Act and Subsection 10(1) of the Packaging and Transport of Nuclear Substances Regulations, 2015 and to the IAEA's Regulations for the Safe Transport of Radioactive Material, 2012 Edition.
REGISTRATION OF USE OF PACKAGES All users of this authorization shall register their identity in writing with the Canadian Nuclear Safety Commission prior to the first use of this authorization and shall certify that they possess the instructions necessary for preparation of the package for shipment.
PACKAGE IDENTIFICATION Designer: BWXT Medical Ltd.
Make/Model: F-522 Mode of Transport: Air, Sea, Road, Rail IDENTIFICATION MARK The package shall bear the competent authority identification mark "CDN/2094/B(U)-96".
PACKAGE DESCRIPTION The F-522 package, as shown in Drawing No. F652201-001 (Rev. H) and F652201-002, Rev B consists of an F-522 overpack, either a UK-201 or a F-528 shielding vessel and a containment system.
The overpack consists of a double-walled stainless-steel cylindrical vessel with fittings for lifting and tie-down. The inner space between the stainless steel wall is filled with a closed-cell polyurethane foam used for impact and thermal protection. The overpack uses a top loading lid design which is secured by screws and incorporates a tamper evident seal. A heat shield may be added to restrict access to the top of the package when required.
The shielding vessel consists of depleted uranium encased within stainless steel body and a lid that are attached and sealed together by eight M10 bolts and a silicone O-ring. The depleted uranium thickness is 75 mm for UK-201 and 73 mm for F-528.
The containment system consists of either an F-248X leak proof insert, or stainless steel or zircaloy capsules. The Page 1 of 3
