Question

Both nuclear fusion and nuclear fission reactions
release radioactive waste.
release large amounts of energy.

Answer 1

Short answers
- "Both release large amounts of energy." — True. Both fission and fusion convert small amounts of mass into energy (E = mc^2) and thus release very large amounts of energy per reaction compared with chemical reactions.
- "Both release radioactive waste." — Misleading/partly true. Fission produces large amounts of long‑lived, high‑level radioactive waste (spent fuel, fission products, transuranics). Fusion does not produce comparable amounts of fission‑type waste from the fuel itself (the primary fusion product for D–T is helium, which is non‑radioactive), but fusion reactors produce radioactive waste by neutron activation of structural materials and by tritium handling. That activation waste is generally smaller in volume and has shorter characteristic half‑lives than typical fission waste, though it is still radioactive and must be managed.

If you want, I can give numbers/examples (typical energies per reaction, types and half‑lives of wastes, or how fusion waste is managed).
