Do we need nuclear power for sustainable energy production?
Nuclear power produces nuclear waste.
Radioactive waste cannot be stored securely for ten/hundred thousand years.
Under/Surface ground water source could be contaminated by the radiating elements. Real life case of water contamination
Nuclear power plant produce High-level radioactive waste (Tc-99, I-129 for example) which can be lethal for most forms of life and can still be dangerous for thousands of years. See
It is less about the quantity of nuclear waste. It is about the duration it needs to be taken care of, up to 10000 years. There is not a single thing man has been able to take care for such a long time.
The best available technology for depositing high-level radioactive waste requires deep, stable geological formations, which is not feasible for many countries. (Source: IAEA Safety Standards: Classification of radioactive waste, link:
Newer reactor designs can also use most of the long-lived "waste" as fuel. The remaining radioactive waste is minuscule in volume and can be safely stored on-site.
Even if we stopped operating nuclear power plants, we still would have to care for all the waste that was produced until now and the waste that is produced in other industry sectors like nuclear medicine. The amount of additional waste does not change the situation significantly.
We can handle radioactive waste.
Nuclear waste from the Uranium Fuel Cycle is
