How are spent fuel rods stored
Did you know?
Spent fuel pools (SFP) are storage pools (or "ponds" in the United Kingdom) for spent fuel from nuclear reactors. They are typically 40 or more feet (12 m) deep, with the bottom 14 feet (4.3 m) equipped with storage racks designed to hold fuel assemblies removed from reactors. A reactor's local pool is specially designed for the reactor in which the fuel was used and is situated at the react… Web14 de set. de 2024 · The spent fuel would be shipped by rail from nuclear plants across the U.S. The used fuel assemblies are sealed in casks which are then encased in concrete, and which would then be stored above ...
