NUCLEAR SAFETY IN HANDLING U-Zr COMPACTS

Technical Report ·
OSTI ID:4800002

Nuclear safety criteria are given for the handling of 11/2-in. by 11/2- in. compacts having a composition of 10 wt.% highly enriched U and 90 wt.% Zr. The maximum safe batch size for these compacts is 1.68 kg contained-U/sup 235, independent of spacing between compacts or the degree of water flooding. For long compacts the maximum safe mass per unit length is 0.94 kg contained-U/sup 235//ft of length. This, too, is independent of spacing between compacts or the degree of water flooding. Maximum safe batches containing no more than 1.68 kg U/ sup 235/ each are safe with a minimum edgeto-edge spacing of 20 in. (auth)
