ABSTRACT:
A method of straightening an irradiated fuel assembly having a plurality of control rod guide thimbles in which some of the guide thimbles are bowed and thus greater in length than other of the guide thimbles comprises the steps of determining the length adjustments required for shortening the respective bowed guide thimbles in order to make their respective lengths generally the same as the other guide thimbles, and then forming expansions in the bowed guide thimbles so as to shorten their respective lengths by the amounts of the length adjustments. Usually, a plurality of expansions are made in most of the bowed guide thimbles at spaced locations between opposite ends thereof. Some of the expansions differ in the amount of shortening from other of the expansions. Also, the total amount of shortening of the bowed guide thimbles is controlled by the number of the expansions and the amount of shortening which results from each expansion. Thus, a straightened skeletal structural of a fuel assembly comprises a plurality of guide thimbles each having opposite ends and top and bottom end nozzles connected to the opposite ends of the guide thimbles. Some of guide thimbles have at least one expansion formed thereon between their opposite ends so as to shorten them relative to other of guide thimbles having no corresponding expansion formed thereon and thereby make the respective lengths of the guide thimbles generally the same.
