摘要 |
Device for locking a guide ring on a plate having an orifice comprising a tubular intermediate piece (22) fastened rigidly to a plate (20) so that its central orifice (36) is coaxial with the orifice (32) in the plate (20), receptacles (28) machined radially in the intermediate piece (22) and separated by passages open towards one end of the intermediate piece, and attachment parts (39) which match the receptacles (28) of the intermediate piece (22) and which are associated with the guide ring (21). The invention is used particularly for locking the guide ring of an extension piece on a guide tube of a light-water nuclear reactor.
