How comes there is nuclear fuel waste when uranium stays radioactive for hundreds of years shouldn’t we be able to use the same fuel rod until 2122+?

We *could* use the fuel for much longer, by using more efficient reactor designs such as [breeder reactors](https://en.wikipedia.org/wiki/Breeder_reactor).
We don’t because it’s just cheaper to dig more Uranium out of the ground. Uranium is dirt cheap compared to how much energy you can get from a kilogram of it.
