High Pressure Laser Welding Of Nuclear Fuel Rods

View page
US Patent:
59582677, Sep 28, 1999
Filed:
Jul 21, 1997
Appl. No.:
8/897142
Inventors:
Andrew A. Lingenfelter - Wilmington NC
James M. Gehr - Wilmington NC
Johnny R. Skipper - Leland NC
Robert J. Sziemkiewicz - Wilmington NC
Jeffrey P. Johnson - Castle Hayne NC
Robert A. Haughton - Wilmington NC
Harry L. Batson - Winnabow NC
Jaime A. Zuloaga - Wilmington NC
Michael T. Kiernan - Wilmington NC
John L. Harmon - Wilmington NC
Edward G. Apple - Wilmington NC
Assignee:
General Electric Company - Schenectady NY
International Classification:
B23K 2612
US Classification:
21912163
Abstract:
A high pressure laser welding method and apparatus enables seam welding of a nuclear fuel rod at hyperbaric pressure. In an automatic process, a loaded fuel rod and an upper end plug are mated within a sealable weld box. A pressure within the weld box is controlled relative to a pressure within the fuel rod, and a laser assembly welds the seam at hyperbaric pressure. Helium flowing through a laser window nozzle during welding prevents soot contamination of the laser window glass and prevents formation of ionic plasma. The upper end plug fuel rod welding operation is thus reduced to a single step and eliminates inspection related tasks with respect to a sealed hole.

Apparatus For Assembling And Welding Final End Plugs To Nuclear Fuel-Containing Cladding Tubes And Inspecting The Welds, All On An Automated Basis

US Patent:
53757564, Dec 27, 1994
Filed:
Mar 31, 1993
Appl. No.:
8/040974
Inventors:
Robert A. Haughton - Wilmington NC
James D. Landry - Wilmington NC
Ralph J. Reda - Wilmington NC
Robert J. Sziemkiewicz - Wilmington NC
Assignee:
General Electric Company - San Jose CA
International Classification:
B23K 902
B23K 3700
US Classification:
228 10
Abstract:
In an automated final weld apparatus, a transporter conveys nuclear fuel-loaded cladding tubes successively to a check station to verify the presence of a plenum spring in the open end of each cladding tube, a reader station where a unique first end plug serial number is read, an evacuation/backfill station where the cladding tube is backfilled with helium, a seam welding station where a final end plug is welded to the cladding tube open end, and a seal weld station where the tube is pressurized with helium through a pressurization hole in the final end plug, whereupon the pressurization hole is welded closed. After checking for helium leakage, the seam weld is inspected in a succession of inspection stations, and, depending on inspection results, the finished nuclear fuel rods are sorted into accepted and rejected lots.
