Fissile DOT Shipment Question

["Gregory R. Larson" <larsongr@email.cind.ornl.gov>]

To All,

Have a DOT question...

Need some assistance with how the DOT regs work with this situation; waste consisting of soil, concrete, rubble, etc. has quantifiable Uranium with an enrichment of 11.7%, material would be considered homogenous due to the waste matrix composition.  All characterization data and identified decay chains are consistent with the parent and progeny activity ratios.  Summation of all activity is less than 70 Bq/gram therefore does not meet the definition of DOT rad material.  Summation of the fissile gram equivalents equates to approximately 32 grams total in the container.

Based on this data, this waste does not meet the definition of Class 7 material.  Does the fissile quantity come into consideration in any fashion or is this simply a DOT non rad shipment?

Thanks in advance for your help...
