Also, as I can see, Tri-Addon (ASP part of it) adds recipes for uranium ingot.
These recipes use as input crushed uranium, purified uranium, uranium ore, enriched uranium fuel.
But, see on other IC2 recipes with uranium. These ones use uranium ingot as equivalent of uranium-238.
So, I highly recommend to add just one recipe to compress uranium-238 to uranium ingot instead of all recipes, which mod adds currently.
Also, it would be very helpful to have (extractor) recipes for converting uranium and iridium ingots back into uranium-238 and iridium ore.
