ABSTRACT:
Method and apparatus for forming a braze joint along the intersection of grid straps of a nuclear fuel assembly. A substantially cylindrical mold having a cavity therein for holding a braze material and having notches near its bottom end complementary to the grid straps is placed on the grid such that the centerline of the mold is substantially colinear with the intersection of the grid straps. Upon heating the grid and mold assembly, the braze material that has been placed in the mold cavity flows by gravity along the intersection of the grid straps which upon cooling forms a brazed joint.
