摘要： PROBLEM TO BE SOLVED: To establish a technique capable of securing high reliability by reliably verifying the physical state of the inside of a canister.
SOLUTION: This storage system for recycle fuel is constituted of a first temperature measuring device 17 arranged at a first location in a convection space 10 inside a storage body (cask) 4 for measuring a first temperature; a second temperature measuring device 21 arranged at a second location for measuring a second temperature; and a computer 3 for computing a soundness index for numerically and statistically evaluating the soundness of the storage body 4 by predicting a future temperature of the first location based on the difference between the first temperature and the second temperature. The temperature difference takes a time-serial measurement value. The soundness is judged based on the temperature difference between the two locations in the convection space 10. The statistical and numerical judgment based on the temperatures at two points which affect each other is substantially superior to statistical and numerical judgment based on an individual and noncorrelating temperature at one point in the respect of soundness judgment.

摘要： PROBLEM TO BE SOLVED: To reduce the construction cost of cask storage building by dispensing an overhead crane used for moving a cask.
SOLUTION: The frame 1 for fixing a cask comprises an air pallet mount 4 capable of detaching an air pallet 5, fixing bolts 3 fixing the nearly cylindrical cask 2 as vertically put on the frame 1, and a placement plane 1a for placing the frame 1 on a floor 8. The air pallet 5 is mounted on the air pallet mount 4. In the case that compressed gas is discharged out of the air pallet 5, the cask receives buoyancy force from the air pallet 5. Taking advantage of the buoyancy force, the cask is moved to a specific location along the floor 8 and then is stably self-stood on the floor 8 at the placement plane 1a.
