Storing all of the highly active radioactive waste that France produced over a year takes about 47 40-foot shipping containers.

Small feeder shops can contain a few hundred containers. Actual container shops contain thousands.

47 does not seem like much?

And what about the mid to low radioactive waste? Also let's not forget France does not have any long term storage facility for their highly radioactive waste yet. Why if it is so easy have they not managed?

Nuclear-level containment on geological timescales is potentially impossible.

Its not like you can put it into a dump and its "gone" like household trash. Radioactivity is ionizing, so it corrodes all materials and cannot be physically contained. The earth's crust is to porous (i mentioned the radon problem in another post) to keep it underground.
