What are the advantages and disadvantages of nuclear power?

When an atom of uranium-235 is bombarded with neutrons, it splits into smaller nuclei and produces a great amount of energy. This nuclear process is called O fission. O fusion. O ionization. O transmutation.

5.How does the US government handle low-level nuclear waste? A.The waste is submerged in water until it no longer produces dangerous levels of heat. B.The waste is stored at a temporary location, then moved to a remote location for long-term storage. C.The waste is transported without shielding, then compacted and buried. D.The waste is cast in concrete and put in a remote, isolated location for long-term storage.
