The challenge of making nuclear power safer doesn't end after the power has been generated. Nuclear fuel remains dangerously radioactive for thousands of years after it is no longer useful in a commercial reactor. The resulting waste disposal problem has become a major challenge for policymakers.
Nuclear waste. Other than that probably plastic because it is not biodegradable.
These are wastes emitting nuclear radiations.
On the power station sites mostly
easily recovered
No, it is not.
All countries that have nuclear reactors have nuclear waste and it is always a problem, though a manageable one.
Yes, but it is a manageable problem
Three problems associated with nuclear waste
The greatest problem with nuclear energy is the potential for catastrophic accidents, such as meltdowns like those seen at Chernobyl and Fukushima. These accidents can have long-lasting environmental and health consequences. Additionally, nuclear waste disposal remains a significant challenge as there is currently no universally accepted solution for storing radioactive waste.
Nuclear wastes are sometimes said to be a problem too difficult to solve because the waste stays radioactive for so long. The only thing that gets rid of nuclear waste is time.
Nuclear fusion produces very little waste compared to nuclear fission. The waste produced by nuclear fusion is mainly low-level radioactive material, which is easier to manage and has a shorter lifespan.
Disposing it.
