(a) For any package containing water and/or organic substances which could i
radiolytically generate combustible gases, determination must be made by
.B, I
tests and measurements or by analysis of a representative package such that h
j'g I
the following criteria are met over a period of time that is twice the l
expected shipment time:
(1) The hydrogen generated must be limited to a molar quantity that would I

be no more than 5% by volume (or equivalent limits for other inflam-l I
mablegases)ofthesecondarycontaigergasvoidifpresentatSTP l
l (i.e., no more than 0.063 g-moles /ft at 14.7 psia and 70*F); or y
l (ii) The secondary container and cask cavity must be inerted with a diluent to assure that oxygen must be limited to 51 by volume in those portions l
i 1
of the package which could have hydrogen greater than 5%.
l J
For any package delivered to a carrier for transport, the secondary container
]
must be prepared for shipment in the same manner in which determination for gas generation is made.
Shipment period begins when the package is prepared j
(sealed) and must be completed within twice the expected shipment time.

1 (b)
For any package shipped within 10 days of preparation, or within 10 days I
after venting of drums or other secondary containers, the determination in j
