Hmm...I've clearly done something wrong when installing the mods.
If I leave the industrial craft config file with all the stuff with hashes in front of it I can log into Minecraft fine and join the server fine, but when I try and mine uranium nothing drops and the block disappears.
However if I remove the hash from before the line 'addMineableOres=true' minecraft throws a wobbly and won't even let me start the game up.
Ideas or should I just delete everything and try again?
Edit - I can make plant clumps however so I assume the rest of the mod is working...hmm
Edit 2 - You need an iron pickaxe to mine uranium
I'm an idiot
