  • This paper addresses the refurbishment procedures for existing shipping containers for 30-inch diameter UF{sub 6} cylinders in accordance with DOT Specification 21PF-1 and the criteria used to determine rejection when such packages are unsuitable for refurbishment.
  • Radioactive materials that do not require much shielding are frequently shipped inside steel drums with cane fiberboard dunnage between the containment vessel and the steel drum. The cane fiberboard serves two purposes; 1) it cushions the containment vessel from impact and puncture and 2) it thermally protects the containment vessel from fire all as defined by the hypothetical accident tests specified in 10 CFR 71.73. Cane fiberboard provides the thermal protection by two mechanisms, insulation and sacrificial decomposition. This paper discusses the more important of the two, sacrificial decomposition, the design features that are important to the thermal performance ofmore » the package and the range of acceptable variation in these features.« less
  • The Type B Drum package is a container in which a single drum containing Type B quantities of radioactive material will be packaged for shipment. The Type B Drum containers are being developed to fill a void in the packaging and transportation capabilities of the US Department of Energy (DOE), as no double containment packaging for single drums of Type B radioactive material is currently available. Several multiple-drum containers and shielded casks presently exist. However, the size and weight of these containers present multiple operational challenges for single-drum shipments. The Type B Drum containers will offer one unshielded version and,more » if needed, two shielded versions, and will provide for the option of either single or double containment. The primary users of the Type B Drum container will be any organization with a need to ship single drums of Type B radioactive material. Those users include laboratories, waste retrieval facilities, emergency response teams, and small facilities.« less
  • The design of the overpacks in drum packages, both in terms of thickness and materials of construction, greatly impact the ability of the package to accommodate heat source contents. The optimum overpack thermal protection needed is that which results in the lowest containment vessel temperature during both Hypothetical Accident Conditions (HAC) and Normal Conditions of Transport (NCT). For heat source packages, the use of very good or high efficiency insulating materials such as fiberboard and polyurethane results in high containment vessel temperatures during both NCT and HAC. Using a more modest or low efficiency insulating material would reduce the NCTmore » and HAC material such as oak (low efficiency) would maintain a containment vessel with a content of 100 watts at a fraction of the temperature reported for very good or high efficiency insulating materials. Four inches of oak can prevent the containment vessel from exceeding 500{degrees}F during both NCT and HAC with 100 watts of contents, whereas using a high efficiency material the vessel would exceed 1000{degrees}F. 8 figs., 1 tab.« less
