about nuclear waste
Answers
Explanation:
Nuclear waste is the material that nuclear fuel becomes after it is used in a reactor. From the outside, it looks exactly like the fuel that was loaded into the reactor — typically assemblies of metal rods enclosing fuel pellets. But since nuclear reactions have occurred, the contents aren’t quite the same.
Nuclear energy is released when a nuclear fuel nucleus snaps into two. The key component of nuclear waste is the leftover smaller nuclei, known as fission products

Radioactive waste is a type of hazardous waste that contains radioactive material. Radioactive waste is usually a by-product of nuclear power generation and other applications of nuclear fission or nuclear technology, such as research and medicine. Radioactive waste is regulated by government agencies in order to protect human health and the environment.
Radioactivity naturally decreases over time, so radioactive waste has to be isolated and confined in appropriate disposal facilities for a sufficient period until it no longer poses a threat. The time radioactive waste must be stored for depends on the type of waste and radioactive isotopes. Current approaches to managing radioactive waste have been segregation and storage for short-lived waste, near-surface disposal for low and some intermediate-level waste, and burial in a deep geological repository or transmutation for the high-level waste.
A summary of the amounts of radioactive waste and management approaches for most developed countries are presented and reviewed periodically as part of the International Atomic Energy Agency (IAEA) Joint Convention on the Safety of Spent Fuel Management and on the Safety of Radioactive Waste Management.
