Beschreibung
Zusammenfassung:	FIELD: nuclear power engineering; fuel elements for water cooled and water moderated nuclear reactors. ^ SUBSTANCE: proposed guide channel for fuel assemblies primarily used for type VVER-1000 reactors has tube and tip. The latter is essentially prefabricated structure. One part of mentioned structure is welded to tube on one of its ends disposed under outer surface of tube. Maximal diameter of tip external part welded to tube is not less than outer diameter of tube and diameter of metal portion disposed between tube end and maximal-diameter part of tip deformed in the course of welding. ^ EFFECT: enhanced manufacturability and performance characteristics of guide channel. ^ 1 cl, 1 dwg
