1) Catastrophic accidents and radiation release
- Although rare, accidents (e.g., Chernobyl 1986, Fukushima 2011) can release large amounts of radioactive material, causing acute health effects, long‑term cancers, large‑area contamination, evacuations, economic loss and ecological damage.
- Risk is reduced by modern reactor designs, safety systems and regulation, but the potential consequences remain high.
2) Long‑lived radioactive waste
- Spent nuclear fuel and some reactor byproducts remain hazardous for thousands to hundreds of thousands of years and require secure, monitored storage and permanent disposal (deep geological repositories).
- Safe long‑term management is technically challenging, politically controversial and costly; many countries still lack finalized permanent disposal solutions.
3) Proliferation and security risks
- Civilian nuclear technology (uranium enrichment, plutonium reprocessing) can be diverted to produce fissile material for nuclear weapons.
- Nuclear facilities and material are also potential targets for theft, sabotage or terrorism, requiring strict safeguards, export controls and physical security.
