Estimating the term…
A bundle of individual measuring lines extends through the cover of a reactor pressure vessel, the bundle extending into a tubular mounting having a multiplicity of extending tubes through which the individual lines of the bundle extend. In each tube the line is passed through a sleeve slidably inserted in the tube and having an inner portion soldered to the line and an outer portion welded to the tube's outer end. The length of the sleeve and tube between the soldered and welded joints is made sufficient to prevent the heat of welding from effecting the soldered joints. Each line can be removed from its tube by cutting away the welded joint and removing the line with its sleeve from the tube. The line can be reinstalled by returning the sleeve to its tube and making a new welded joint with the sleeve spacing its soldered connection with the line far enough to prevent the welding heat from affecting the soldered joint between the sleeve and the line.
A nuclear reactor pressure vessel having a passage through which a bundle of individual measuring lines extends, a tubular mounting having an inner end provided with releasable means for releasably connecting it to said vessel with said bundle projecting into the mounting and the mounting having an outer end from which a multiplicity of tubes start and extend to terminal ends with said lines extending individually from the bundle through individual ones of the tubes and beyond their terminal ends, each line being passed through a sleeve slidably inserted in the tube through which the line extends and the sleeve having an inner portion with a terminal end within the tube and which portion has a soldered joint with the line and the sleeve having an outer portion projecting beyond the tube's terminal end, each tube having a length between the soldered and welded joints long enough to permit welding of the welded joint without melting of the soldered joint.
