Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
107 words
A container for transportation of radioactive material comprising an impact resistent outer vessel constructed from a plurality of parts, interfitting to define a hermetically sealable chamber, an inner container, the outer surfaces of which conform to the inner surfaces of the outer vessel, said inner container removably located in said chamber, said inner container constructed of a plurality of radioactive shielding inserts interfitting to define a second closable chamber therein, said inserts being interchangeable with similar inserts such that the dimensions of said second chamber may be selectively varied to accommodate different shapes and sizes of said material without necessarily adjusting the dimensions of the outer vessel.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
37 words
A container according to claim 1, wherein the outer vessel comprises a body portion, a removable lid and a wall extension portion adapted for insertion between said body portion and said lid to accommodate long length loads.
