Improvements in or relating to nuclear reactor fuel assembly arrangement

Description

A grid-thimble joint for a reactor fuel assembly is described. The basic fuel element structure is in part fabricated from materials having low neutron capture cross section while the critical grid-thimble joint is obtained without any reduction in overall fuel assembly structural strength or integrity. The joint is so constructed that the need to metallurgically bond dissimilar materials is eliminated. Also the need to elastically and permanently deform a structural member within the basic fuel assembly is eliminated. The joint is accomplished by snapping a sleeve into place within a grid cell and then welding a guide thimble to the sleeve. (author)
