The U.S. Nuclear Regulatory Commission (NRC) is updating the regulations for storing used nuclear fuel by revising a listing for the Holtec International HI-STORM 100 Cask System. This amendment, known as Renewed Amendment No. 19, changes the rules to better handle accidents where the cask tips over by introducing new stress-based criteria and evaluation methods. It will become effective on May 27, 2025, unless significant negative comments are received by April 14, 2025. The NRC believes this update does not significantly change the design and ensures public safety and environmental protection remain at acceptable levels.
Simple Explanation
The people in charge of nuclear safety are updating the rules for how to safely store old, used nuclear energy stuff to make sure they don't fall over. They're changing how they check for accidents, and these new rules will start in May 2025 unless lots of people tell them they don't like them by April 2025.
