When i flooded the screen with neut then put some plut out then unpaused while i was in heat view.Then paused again a few seconds later when you put your mouse over the pink spots its says uran evan though i never put any uran out.
Oh ok its a bi product i would of never noticed because i only use plut in nukes.But the nukes have uran with the plut already before fission.So if i saw any uran i thought it was the uran already there before.
