The waste is a non-problem, especially when you compare with co2 over decades.
Nuclear energy emits less co2 than renewables: it requires less metals (especially if you store electricity with batteries or other means), and renewables are not baseload energies, meaning you need to burn either coal or gas when there's no sun or wind.
Wind mills require a lot of metals, and installing them is complicated. Solar panels require mining elements, and solar panels degrade over time.

Nuclear energy is green. It's time to say it.
