why is japan producing this material in the first place?

I believe it's a by-product of their electricity generation.

What do they do with all that plutonium?

Search me.

I thought the rods were uranium and that a special refinement process had to take place to extract the plutonium. Is it easier to refine these spent rods and then store them? Plutonium is very dangerous even in small amounts, tons of it on a small island with a history of earthquakes would seem a disproportionate risk.

just a carpenters point of view
