WASHINGTON, D. C. 20555
.....,o Transportation Certification Branch Approval Record Combustible Gas Mixtures Conditions were imposed on packages containing water and/or organic substances to limit the accumulation of radiolytically generated gases
~
over the shipping period to preclude the possibility of significantly reducing the packaging effectiveness due to explosion.
Part of the conditions included
"...it must be detemined by tests and measurecents of a representative package whether or not...."
There is no reason to believe that calculational methods could not be used as means of determining gas generation. So as not to preclude a valid analysis, part of the condition to limit the accumulation of radiolytically generated gases is revised to read "...it must te detemined by tests.and measurements or by analysis of a representative package whether or not...."
The analytic approach involves detennining the hydrogen generated in the waste by radiolysis based on the absorbed dose of the waste over a given period of time. To satisfy the condition to preclude a combustible mixture, the period since closure ~.and twice the shipping time must be considered. The calculation requires that the properties of the waste are known.
These properties may be determined from test and measurement of representative waste foms or from data that is applicable to the waste fann. The determination should be documented and retained as part of the records for the shipment.
