This report presents a basic description of the fabrication processes used to assemble the Light Water Breeder Reactor (LWBR) seed, blanket and reflector fuel assemblies. Each type of fuel assembly is described and illustrated in detail and process data are presented. New technology specifically developed as a result of the LWBR program is described. This includes an evaluation of factors affecting fuel rod installation forces, a torque-turn method to secure the fuel rods to the assembly baseplates and a portable welding process used to lockweld Zircaloy hardware. A description of the facility used to fabricate the fuel assemblies is presented in an appendix to the report.
