PROBLEM TO BE SOLVED: To provide a hanging structure for a radioactive substance storage container capable of simplifying the structure to maintain engagement between each trunnion provided in the radioactive substance storage container and a hanging device for hanging the radioactive substance storage container and reducing a load applied to each trunnion.SOLUTION: The hanging structure includes: a locking hole 42 formed at the end part of a protrusion of each trunnion 41 arranged to protrude outward from cask (radioactive substance storage container); a locking shaft 55 provided on a hanging device 51 for hanging the cask to be inserted into the locking hole 42; a recess 42a provided in the bottom of the locking hole 42 to be recessed in the cross direction across the insertion direction of the locking shaft 55; a protrusion 55a provided on the tip of the locking shaft 55 to protrude in the cross direction across the insertion direction of the locking shaft 55 to be engaged with the recess 42a; and a travel regulation part 56 which regulates travelling of the locking shaft 55 in a direction against the cross direction in a state of engagement of the protrusion 55a with the recess 42a by inserting the locking shaft 55 in the locking hole 42 to move it in the cross direction.SELECTED DRAWING: Figure 13 |
