Abstract: A storage/transport container for intact and broken nuclear-fuel elements has a vessel defining an interior extending along an axis and a plurality of like basket sections forming a stack extending substantially a full axial length of the interior and forming a plurality of axial full-length rectangular-section wells. Respective metal tubes extending substantially the full length of some of the wells are of complementary section to the respective wells and are each adapted to snugly hold an intact spent nuclear-fuel element. At least one box extending substantially the full length of others of the wells is of complementary section to the respective well and is adapted to hold pieces of a broken spent nuclear-fuel element.
