Anion-deficient actinide nitrate solution
Patent
·
OSTI ID:7190845
A method is described for the preparation of anion deficient actinide nitrate solutions of a high concentration suitable for use as starting materials for preparation of spherical ceramic nuclear fuels. The anion deficient nitrates are prepared by dissolving the actinide oxides in hydrated actinide nitrates which melt in their own water of crystallization. The actinide oxides to be dissolved may be selected from the group of PuO/sub 2/, UO/sub 2/, U/sub 3/O/sub 8/, UO/sub 3/ or lower oxides than UO/sub 3/ located between UO/sub 2/ and UO/sub 3/. The compounds Th(NO/sub 3/)/sub 4/.4H/sub 2/O, UO/sub 2/(NO/sub 3/)/sub 2/.6H/sub 2/O or mixtures of these salts may be used as hydrated actinic nitrates. 8 claims, no drawings. (BLM)
