(1) Model No.: HN-100S !g l
(2) Description j B l The cask is a steel annulus'84-1/4 inches high by 81-5/8 j inches in diameter. The cavity is. 75-1/2 inches high by .g 75-5/8 inches in diameter. The side walls consist of two g l
i plys of 1-1/2-inch steel. The 3-inch steel t'ase is l1 l integrally welded to the cylinder. The lid is a 3-inch R steel plate, stepped to mate with the upper flange of the 8 j
cylinder. A centrally located shield plug is similarly
! cons tructed . The lid and plug are attached with stud- gl l bolts and nuts and sealed with Buna N 0-ring gaskets. A g plugged drain line and/or optional vent / test in the j#
j secondary lid connection is provided. Four skewed lugs welded to the outer shell are used for tie down. There j
fj are three cask lifting lugs, three lid lifting lugs, and one shield plug lifting lug. The package gross weight is
, approximately 43,000 pounds. lW I g ,
[ (3) Drawings j E
The packaging is fabricated in accordance with Hittman Nuclear & Development Corporation Drawing Nos.:
9128, Rev. 4 and C001-5-9129, Rev. 3.

Transportation Certification Branch Approval Record Model No. HN-100S Package Docket No. 71-9089 By application dated April 19, 1985, Westinghouse Hittman Nuclear Incorporated requested an amendment to the Model -No. HN-100S package. The amendment provides for an alternate method of installing the optional drain plug to the package.
The change has no significant impact on the ability of the package design to meet the requirements of 10 CFR Part 71.
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 measurements of a representative package whether or not...."
There is no reason to believe that calculational methods could not be used as means of detemining 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 detemined by tests and measurements or by analysis of a representative package whether or not...."
The analytic approach involves detemining 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 cembustible 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 form. The determination should be documented and retained as part of the records for the shipment.
