Located in Oak Ridge, Tennessee Operating production facility specializing in uranium material safeguards, technologies, and manufacturing:
Since FY06, Y-12 has been integrated in fuel development activities supporting the RERTR Program goals. This presentation will focus on the capabilities that might be of interest to the Mo99 community
Support directly the Materials Management and Minimization (M3) Goals

Target foil thickness is difficult to manufacture
U foil more difficult to roll than U/Mo Heat Treat Anneals Necessary for desired thickness
100 µm foils are now possible.

1. 5%Al, 93%Al2O3, 2%NH4Cl 2. 10%Al, 88%Al2O3, 2% NH4Cl 3. 800~900°C for 1 to 6 hrs
FY19:
Process*: Pack aluminizing is a diffusion process
1. Diffusion of Al halides (AlCl3, AlCl2, AlCl) through the vapor phase in the porous pack medium 2. Reaction of Al halide AlCl2 with the substrate at temperatures <1000°C 3. Diffusion of Al in the solid phase to form aluminide coating layer
