Why don't we force nuclear decay ?

Today my physics teacher was telling us about nuclear decay and how happens (we need to put used uranium that we cant get anymore energy from in a concrete coffin until it decays) but i learnt that nuclear fission(how me make nuclear power) causes decay every time the uranium splits. So why don't we keep decaying the uranium until it isn't radioactive anymore?

We can't force nuclei to decay, but we can make them undergo reactions that turn them into other nuclei which decay faster.

There is some promise of doing this with waste from nuclear reactors, so that we don't have to store it as long.
