Abstract
Abstract A container for transporting radioactive materials utilizing a removable system of heat conducting fins is provided which permits a substantial reduction in the weight of the container during transport, increases the heat dissipation capability of the container and substantially reduces the scrubbing operation after loading and unloading the radioactive material from the container. The detachable fins are made of a light weight highly heat conductive metal such as aluminum or aluminum alloys.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
20 words
The container of claim 1 wherein said cavity is of substantially the same dimensions as the radioactive material contained therein.
Claim 2
Dependent Claim
15 words
The container of claim 1 wherein said fins are made of aluminum or aluminum alloys.
Claim 3
Dependent Claim
22 words
The container of claim 1 where said beta gamma absorbing materail is depleted uranium and said corrosion resistant material is stainless steel.
Claim 4
Dependent Claim
30 words
The container of claim 1 which further comprises a jacket for holding a neutron attenuating substance, said jacket being disposed between the beta gamma absorbing material and the outer wall.
Claim 5
Dependent Claim
35 words
The container of claim 1 wherein said fins are vertically disposed on plates of the same metal as the fins, said plates being mounted in heat conductive relationship on the skin of corrosion resistant metal.
Claim 6
Dependent Claim
20 words
The container of claim 1 wherein said heat dissipating fins are less corrosion-resistant than said outer wall to decontamination solutions.
Claim 7
Dependent Claim
24 words
The container of claim 1 wherein said heat dissipating fins sufficiently envelop said outer wall to protect said wall from environmental contamination during transport.
Claim 8
Dependent Claim
77 words
In a container for transporting radioactive materials which includes a body of beta gamma absorbing material with a central cavity disposed therein for holding said material, an outer skin of corrosion-resistant metal surrounding said body, and heat dissipating fins in heat conductive relationship with said outer skin, the improvement which comprises removably mounting said fins to said outer skin and constructing said fins from a lighter weight, greater heat conductive, less corrosion-resistance metal than said outer skin.
Claim 9
Dependent Claim
15 words
The container of claim 9 wherein said fins are made of aluminum or aluminum alloy.
Claim 10
Dependent Claim
35 words
The container of claim 9 wherein said fins are disposed on plates of the same metal as the fins, said plates being mounted in heat conductive relationship on the skin of said corrosion resistant metal.
