ABSTRACT:
Evaluation for deformations of the channel box of a fuel assembly in a nuclear reactor core in which deformations of the channel box which has been used for exposure so as to be deformed are estimated for future exposure through computation and process of data of core characteristics, data of material properties and shapes of channel boxes, data of initial deformations of the channel box, data of loading patterns and the like, thereby to judge whether the estimated deformations are agreeable for reusing the channel box in the future exposure, or not.
