Zusammenfassung:	The present disclosure provides for designs of fuel assemblies and may be used in pressurized water reactors. In some embodiments, a nuclear reactor fuel assembly may comprise a bundle of fuel rods, guide channels, two nozzles, one of which has a bearing plate with openings, elements for the detachable connection of the nozzles to the guide channels, a detachable connection locking device and a locking device fasteners, the elements for the detachable connection of the nozzles to the guide channels have a cross-section size greater than the size of the openings in the nozzle bearing plate. The present disclosure may provide greater ease in loading and unloading, reduce the time required for the mounting and removal of the nozzles during manufacture of the fuel assembly, and reduce the length of the reactor refueling process.
