GUIDE CHANNEL Russian patent published in 2000 - IPC

Abstract RU 2152084 C1

FIELD: nuclear power engineering. SUBSTANCE: guide channel related to fuel assemblies of VVER-1000 power reactors has its tip connected to tube through additional bushing made of tube material; novelty is that some portion of bushing placed inside tube is stripped therein to ensure clearance between inner surface of tube and mentioned portion of bushing while its other portion which is outside the tube and does not take part in weld formation has its diameter greater than maximal diameter of tip but smaller than outer diameter of tube. EFFECT: improved operating reliability of fuel assembly. 1 dwg
