Why is fresh uranium fuel safe to handle with standard PPE while “spent” fuel is so hazardous?

691 viewsChemistryOther

My uninitiated mind would think that it would be the other way around.

I was watching a video about nuclear power. The guy being interviewed was wearing safety glasses and nitrile gloves while holding a uranium fuel pellet. Then the camera pans to a screen showing the robot handling spent fuel in the bottom of a 40-foot deep pool of heavy water. The pool is in a room behind a big red door with every “do not enter” warning imaginable. I would think the fuel would be less radioactive coming out than going in.

The fuel works by turning into other stuff. 

When it’s spent it has turned from something safe into something that isn’t safe. 

Also you can touch fresh food (sandwich) with bare hands but you shouldn’t touch spent food (poop) after your body (reactor) has used it for fuel
