The General Purpose Fissile Package (GPFP) is a robust, single containment package, capable of
transporting Plutonium and Uranium metals and oxides. The DOT 6M specification package is
being withdrawn from service and the GPFP has been designed as a robust, cost-effective,
user-friendly replacement. The design incorporates the proven Chalfont type containment vessel,
employed by the widely used 9975 package. Based on the package size and proposed contents,
its evaluation includes the 10CFR71.73 "Crush" test. To ensure this capability, the package
overpack was constructed using urethane foam and load distribution features. Testing has
confirmed the package's ability to withstand the hypothetical accident condition tests, as
specified in the Code of Federal Regulations. The features important to users are discussed and
test results are described in this presentation.
Department of Transportation (DOT) 6M Specification Packages have been used extensively for
the transport of Type B quantities of fissile radioactive materials (uranium and plutonium metals
and compounds) since the 1960's. In recognition of the improved state of the art for radioactive
materials packaging, DOT has instituted a phased elimination of the 6M in favor of packages
certified to meet the performance requirements specified in the Code of Federal Regulations.
Any replacement for the 6M must be economical, user friendly, able to accommodate the
contents authorized for the 6M, and available at an early date.
In response to the need for a Type B packaging to replace the 6M, the Savannah River Packaging
Technology department has developed the General Purpose Fissile Package, or GPFP. In
addition to the requirements listed above, the single containment GPFP design meets the latest
revision of 10CFR71, which eliminated the requirement for double containment for plutonium
contents. For the GPFP to meet a broad range of shipping needs of the Department of Energy,
the GPFP is designed to accommodate materials which meet the DOE 3013 standard and most of
