Supreme Court rules against Texas in interim storage case
The Supreme Court voted 6–3 against Texas and a group of landowners today in a case involving the Nuclear Regulatory Commission’s licensing of a consolidated interim storage facility for spent nuclear fuel, reversing a decision by the 5th Circuit Court of Appeals to grant the state and landowners Fasken Land and Minerals (Fasken) standing to challenge the license.

The composition of NOx generated in the dissolution of UO2 has been described in different ways by earlier authors. Finding a way to determine the NOx composition in the dissolution included experiments concerning the reactions of NO and NO2 with 3 to 6 M HNO3. The following conclusions have been obtained for the dissolution: (a) of the NOx, NO is the direct product of the dissolution [3UO2 + 8HNO3 → 3UO2(NO3)2 + 2NO + 4H2O]; (b) part of the NO is converted quickly to NO2 by the second reaction, i.e., NO + 2HNO3→ 3NO2 + H2O (the equilibrium constant of this reaction determines the NOx composition); (c) the dissolution is therefore expressible as 3UO2 + 4(2 + x)HNO3→3UO2(NO3)2 + 2(1 — x)NO + 6xNO2 + 2(2 + x)H2O, (0 < × < 1) (some values of the × were obtained); (d) the amount of NO2 in the NOx is considerably smaller than that reported by earlier authors, e.g., 25% for 6.7 MHNO3 at 101°C; (e) UO2(NO3)2 coexisting in the solution tends to increase the NO component in the NOx.
