NRC v. Texas: Supreme Court weighs challenge to NRC authority in spent fuel storage case
The State of Texas has not one but two ongoing federal court challenges to the Nuclear Regulatory Commission that could, if successful, turn decades of NRC regulations, precedent, and case law on its head.

Fission-product decay heat rates in shutdown 239Pu-fueled fast reactors are determined by direct calculation using a modified version of the CINDER code with a fission-product library of 344 nuclides. Systematic variations in fluence, flux level, irradiation time, and the initial 238U/239pu ratio are made for the ranges of current interest, and their effects on the decay heat rate for the first ten years after reactor shutdown are investigated. Variations in irradiation history and the 238U/239Pu ratio over the ranges considered cause the total decay heat rate to vary by <18% during the first day after shutdown.
