Which issue poses the greatest long-term challenge in the development of new nuclear power plants?
[a] controlling carbon dioxide emissions
[b] storage of radioactive waste
[c] controlling fission reactions
[d] mining of uranium

Answer is: [B] storage of radioactive waste.

Nuclear (radioactive) waste is hazardous to all forms of life and the environment.

Long term storage of radioactive waste is needed. It is important the stabilization of the waste into a form which will neither react nor degrade over many years.

If nuclear waste is wasted in atmosphere or into oceans and lagre lakes, eventually it will come in contact with living organisms.

Nuclear fission is a nuclear reaction or a radioactive decay where nucleus of atom split into smaller ligher nuclei.
