Creators

Description

This invention concerns a nut plate for a nuclear reactor fuel element in which the fuel element has an array of end portions for engaging the nut plate. This nut plate comprises a plurality of linking members joined together to form a lattice, and nodes where linking members are joined together, at least some of the nodes having apertures formed therein. Each of the apertures is positioned relative to the other nodes in a disposition that matches the fuel element end portion array. The nut plate comprises a plurality of hollow locking cups, each of cups being secured to network of linking members in gemeral alignment with respective node aperture
