Short answer: Fusion — but with an important caveat.
Why:
- Fission: splits heavy nuclei into radioactive fission products and leftover actinides (spent fuel). That produces large amounts of high‑level, long‑lived radioactive waste that needs secure storage for decades to millennia.
- Fusion (e.g., D–T): the primary fuel reaction produces helium (non‑radioactive). However, fusion reactors emit high‑energy neutrons that activate structural materials and can make components radioactive; fusion also uses and breeds tritium, which is radioactive. Overall, the waste from fusion is expected to be much smaller in volume and shorter lived than fission waste.
So if you mean “which process does not produce radioactive waste at all”: strictly speaking, neither is completely free of radioactive byproducts. If you mean “which produces little or no long‑lived high‑level waste”: fusion is the answer.
