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

697 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.

Think of it like this: Before you put something in the oven it is safe to handle, after it spent a bunch of time in a hot oven you can’t pick it up with your bare hands for some time*

*YMMV
