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 dynamic behavior of the failed steam generator tube plug of an operational plant in 1989 can be understood through an analysis that solves the energy equation of the broken plug top and computes its kinetic energy as a function of elevation in the tube. The computed high kinetic energy of the plug top when it reaches the U-bend of the tube can exceed the work required to penetrate the tube wall at that location. If the inlet flow area at the bottom of the tube is small, the plug top exhibits an interesting stop-and-reacceleration behavior.
