Abstract

The assembly is used in nuclear engineering, In particular for the structure of the elements of its rigid framework. The fuel assembly consists of head and rear parts connected to each other by guiding channels arranged in cells of spacer grids. Said guiding channels are rigidly connected to at least the end spacer grids. The height (h) of the spacer grids and the wall thickness delta of the cells thereof are selected in such a way that the quantitative characteristics thereof correspond to the calculated and-experimentally determined conditions. As a result the rigidity of the assembly is improved at transversal and longitudinal bending to increase an angular rigidity the pair - cells of spacer grid. The own bending of the fuel assembly in the sectors between the spacer grids and the free bending of the fuel assembly in non-homogenous neutron and temperature fields is reduced due the decreased tendency of an E635 alloy to radiation growth.
