~

II inches encased in 0.50-inch: thick -inner steel shelliand 1.13-inch ll thick outer steel shell. . The top cover and cask bottom are made up of lg g two s. teel plates ranging in thickness from 2.0 to 3.0 inches. The gj primary cask l'd is secured 'to the' cylindrical cask body by eight, a l 1-1/s-inch rachet binders. An ' optional secondary lid is centered in E Il the primary lid and is secured to the primary lid with eight, 3/4-inch I I s tuds and nuts. Each lid is provided with a Neoprene gasket seal.

The cask may be provided with an optional 12 gauge stainless steel ll l liner (seal welded along all edges), an optional lid vent line with y-g g,

g pipe plug, and an optional 3/4-inch drain line and pipe plug. The t J cask is provided with four equally spaced lifting / tie-down devices. I fl. The primary lid is provided with three lifting lugs and the optional I ,

i secondary lid is provided with one lifting lug. The cask has a gross lg

)l 1 weight of 56,500 pounds.

\...../ .  :

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 detennined by tests and measurements 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 be determined 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 detennined from test and measurement of representative waste fonns or from data that is applicable to the waste form. The determination should be documented and retained as part of the records for the shipment.
