I don't get the nuclear debate

Australia’s politicians are wrapped up at the moment with the idea of a nuclear reactor and expanded uranium mining. I’ve got my own views on it and all, uninformed as they are, but one thing I really don’t get, and it keeps coming up, so I’m asking for your wisdom here. They (media, politicians, etc.) always mention “Well, Oil prices are going up and up… so we should investigate Uranium as an alternative source of energy.”

What?

I think I blink and miss something there, every time. What on earth does oil have to do with uranium?

p.s. if you were wondering where the sunday recipe was… I was too lazy and didn’t cook on Sunday. Next week, promise.
