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.

A series of dose rate calculations in two-layered slab shields has been performed, using a Monte Carlo technique, at combinations of source energy and slab thickness selected with the aid of a composite experiment design. Least-squares fits to the dose buildup factors obtained from these calculations yield equations in which the dose buildup factor is represented as a quadratic function of the source energy and the thicknesses of the materials composing the shield. The accuracy of these equations has been established by comparisons with existing data.
