Two (2) melted Fermi-1 fuel assen,blies (melted in the Fermi-1 reactor incident) each placed in its own seal welded aluminum canister with a 4.375. inch ID and a 0.25. inch aluminum wall. Each canister is to singly eccupy its own ct.vity quadrant. Spacers must be used to prevent nmvement of these canisters. The remaining two quadrants can be used in the sarac shipment holding Zr-clad or unclad intcct Fermi-1 fuel pins in their own aluminum containers, four per cavity quadrant. Seal welded aluminum with greater than pin holes and hairline cracks are not authorized.
Cask Configuration C is to be used for this shipment of a maximum of ten alumi-

Transportation Branch A)prova1 Record gdel J.o. NLI-1/2 Package Docket No. 71-9010 By application dated February 26, 1988 as supplemented on August 22, 1988, Nuclear Assurance Corporation requested a letter amendment to Certificate of Compliance No. 9010, to authorize the transport of two (2) melted Fermi-1 fuel assemblies, each placed in its own aluminum seal-welded canister and each singly occupying its own cavity quadrant with spacers to prevent move-ment of the canisters. The additional two quadrants may contain aluminum canisters holding Zr-clad or unclad intact fermi-1 fuel pins.
.The requested shipment poses no criticality hazard since the original criti-cality analysis assumed all fuel,-clad or declad-to be optimally moderated within the cavity quadrant without taking the aluminum canisters into account.
The melted fuel has a less favorable geometry under moderated or unmoderated conditions and thus poses no hazard in terms of criticality of the cask.
Approval is recommended for the propos(d melted assembly shipment in the NLI-1/2 casic.
