If this was being used as an X-ray source, I doubt it was "depleted uranium"--at least in the sense of the depleted uranium used in armor and ammunition.

Someone please correct me if I am wrong.

I think it’s not being used as an X-Ray source. The article states that it is used in the welds.

The depleted uranium may have been used in the device for shielding against the X-rays.
