I apologize in advance if I am not understanding you, but the process of fission generates new radioactive daughter nuclides and neutron activated material. The radioactivity in a nuclear reactor isn't simply a concentrated aggregate of the original fuel. It is a heterogeneous mixture of transmuted elements that is quite different from the original in its radioactivity.

Not really, because the nuclear fuel would naturally degrade into much the same materials anyway, just over a longer time frame. Nuclear reactors just speed up the process.

Yes that means higher concentrations of those decay products to deal with in the short term, but these mostly have quite short half lives in the grand scheme of things, in the order of years or decades.

The environmental impacts of nuclear energy are often grossly overestimated, this is why so many environmentalists are advocating for nuclear energy.
