Patent Number: 
Section: abstract

A system and method for moving a canister of spent nuclear fuel from a first location, which may be within a nuclear power generation facility to a second location such as a storage cask that is used for short-term or long-term storage of spent nuclear fuel includes a first lifting mechanism for engaging a transfer cask and a second lifting mechanism for engaging and lifting the canister of spent nuclear fuel. Preferably, the method is practiced by first positioning a canister of spent nuclear fuel within the transfer cask and then engaging the transfer cask with the first lifting mechanism. The canister is engaged with the second lifting mechanism. The transfer cask having the canister positioned within is moved to the vicinity of a storage cask, and the canister is lowered from the transfer cask into the storage cask by the second lifting mechanism without disengagement of the first lifting mechanism from the transfer cask. Ideally, the second lifting mechanism is mounted on a portion of the first lifting mechanism that is relatively free from relative movement with respect to the transfer cask during operation. Accordingly, the lowering of the canister may be performed with a minimum of relative movement between the canister and the transfer cask, obviating or reducing the necessity for supplemental tiedowns of the transfer cask during this procedure, which is an inefficient process that if performed incorrectly can expose humans to unwanted radiation.
