Abstract

The invention relates to nuclear engineering, in particular to the structural design of caseless nuclear reactor fuel assemblies. The inventive nuclear reactor fuel assembly comprises a bundle of fuel elements and guiding channels accommodated in spacer grids, a head and a bottom nozzle, wherein the spacer grids are connected to each other and to the bottom nozzle by means of elements arranged along the fuel assembly length and the bottom nozzle consists of a support plate and a support cylinder which are connected to each other. The fuel assembly is characterized in that an antivibrational grid consisting of interconnected cells is disposed above the support plate and in that the antivibrational grid, the support plate and the support cylinder are interconnected by means of at least one fastener. The inventive technical solution makes it possible to substantially extend the service life of fuel elements, thereby increasing fueling load and the depth of fuel burning and considerably extending the service time of a fuel assembly.
