Abstract

The transportation of UF{sup 6} is subject to regulations requiring the evaluation of packaging under a sequence of hypothetical accident conditions including exposure to a 30-min 800{degree}C (1475{degree}F) fire [10 CFR 71.73(c)(3)]. An issue of continuing interest is whether bare cylinders can withstand such a fire without rupturing. To address this issue, a lumped parameter heat transfer/stress analysis model (6FIRE) has been developed to simulate heating to the point of rupture of a cylinder containing UF{sup 6} when it is exposed to a fire. The model is described, then estimates of time to rupture are presented for various cylinder types, fire temperatures, and fill conditions. An assessment of the quantity of UF{sup 6} released from containment after rupture is also presented. Further documentation of the model is referenced.

Thermal analysis of Model 48-14 UF/sub 6/ cylinder overpack using the HEATING5 computer code

Technical Report Burnett, W A

The Model 48-14 protective overpack designed and fabricated by Nuclear Containers, Incorporated of Elizabethton, Tennessee, in a joint development with the US Department of Energy, is being considered for potential use in the shipment of UF/sub 6/ cylinders containing material enriched up to 4.5 wt % in /sup 235/UF/sub 6/. In order to partially satisfy licensing requirements, it must be satisfactorily demonstrated that the overpack and its contents can withstand thermal exposures specified for both normal transportation and accident conditions. Normal transportation conditions consist of exposures to -40/sup 0/F ambient temperature in shade and to 130/sup 0/F ambient temperature inmore »« less
Assessing post-fire combustion of polyurethane

Conference Williams, W R ; Anderson, J C

In defining hypothetical accident condition thermal test requirements, 10 CFR 71.73(c)(3) states that ``any combustion of materials of construction must be allowed to proceed until it terminates naturally.`` Two examples of extended burning of packages following the regulatory fire are documented. This paper addresses extended burning after cessation of the 30-min, 1475{degrees}F regulatory fire from an analytical perspective with specific application to a package containing polyurethane insulation. Issues include identifying conditions under which materials of construction bum, estimating burn rate, and establishing criteria for cessation of burning. These data and criteria are then applied to determine package temperature profiles usingmore »« less

Thermal properties evaluation of UF/sub 6/ cylinder overpack insulation. [phenolic foam]

Conference Frazier, J L

A phenolic foam is incorporated into the design and construction of UF/sub 6/ cylinder shipping containers known as overpacks. The overpack provides mechanical and thermal protection to UF/sub 6/ product cylinders during transport. The phenolic foam is utilized for thermal insulation. An important criterion in overpack design is to limit temperature excursions of the product cylinder below the triple point of UF/sub 6/, preventing possible overpressurization of the cylinder. A current requirement is that the product cylinder wall temperature be maintained below the UF/sub 6/ triple point with the outer surfaces of the overpack exposed to 1475/degree/F for thirty minutes.more »« less

ORGDP Container Test and Development Program Fire Tests of UF6-Filled Cylinders

Technical Report Mallett, A J

Fire tests of bare, UF{sub 6}-filled shipping cylinders were conducted at the ORGDP Rifle Range during October 1965 as part of the AEC-ORO Container Test and Development Program presently under way at the ORGDP. The multi purpose effort was to determine if the cylinders would hydrostatically or explosively rupture; the time available for fire fighting before either incident occurred; and the degree of contamination as related to the type of UF{sub 6} release, wind velocity, and terrain. In addition to the cylinder fire tests, other tests were made for further evaluation of the fire-resistant BOX foam plastic. These included amore »« less
