Why are the fuel rods in nuclear reactors so tall?
I just watched Animagraffs' great video on How Nuclear Power Works https://www.youtube.com/watch?v=PRWwXeRIvoI .
Right at the beginning, the fuel rods and core assembly are shown to be ~2.5x "human sizes" tall. What's the great benefit of having fuel rods that particular length?
As it seems to make transportation, storage, handling and re-fueling much more involved. Since they're filled with pellets anyway, they could be fabricated to any other more (compact) length. I suppose the benefits must outweigh those trade-offs quite a bit.
