- Nuclear Fuel Fabricators & Zircaloy
Tubing Supply provides a review of the nuclear fuel fabrication business and processes while indicating where fabricators acquire their zirconium fuel assembly components.
Evaluation of tribological properties of zircaloy
material is important from viewpoint of its sliding contacts with different materials.
Cylindrical fuel assemblies (black) are located in an aluminum rack surrounded by an aluminum vessel (both purple); the Beryllium reflector (grey) allows locating many devices; some Zircaloy
screens (orange) are also visible.
The core is configured in a 5 x 6 grid surrounded by a Zircaloy
chimney, 10 meters below the pool surface.

First presented are keynote lectures, followed by papers on deformation, including magnesium, severe plastic deformation, accumulative roll bonding and high pressure torsion, modeling, orientation gradient, experimentation research, and creep and superplasticity; deformation and annealing, including cube texture and thermo-mechanical processing; techniques, microstructure, dislocations, x-ray/neutron diffraction, recent advances, and electron backscatter diffraction measurements; annealing, with discussion of grain coarsening, recrystallization, and recovery; and materials, such as corrosion oxidation, interfaces, electrical steel, steel, titanium and zircaloy
, phase transformation, shape memory, nano-structure materials, microstructural engineering, and non-metallic materials.
In some zircaloy
nuclear fuel cladding used in boiling-water reactors (BWR), hydride cracking was found in the form of long splits that allowed substantial leakage of fission products .
The main partners in the nuclear fuel fabrication work were the two large fuel fabrication plants at Electrostal (A-7340), at Ust'-Kamenogorsk (B-8857) and the Glazov metallurgical plant M-5057 at Chepetsk that fabricated the zircaloy
cladding for fuel rods and assemblies.
From 1989 to '99, Stout advanced from task leader for Zircaloy
cladding to technical area leader for waste forth characterization at Lawrence Livermore National Laboratory.
Advances in aqueous fluoride chemistry have been made as the result of processing naval Zircaloy
nuclear fuels for uranium recovery.
