Update of the original Uranium Belts by Spieker to be Factorio 1.0 (tested up to 1.1).
Updated recipe (see screenshots) and speed to be exactly double a blue express belt.
tested with Bobs and many other mods. Works well with bobs as it's faster then bobs fastest belt at 90 items/s compared to bobs 75items/s which isn't quite two express belts.
