Nuclear energy

nuclearNuclear energy has its opportunities and its threats.

  • The opportunities are the supply of an abundance of energy without emission of greenhouse gasses.
  • The threats are intentional or unintentional contamination of the environment with radioactive material by accidents, waste or actions of violence.

Even intrinsically safe nuclear fission power stations may become a terrorist target or of malevolent governments. History shows that practically all potential disasters sooner or later actually occur and that the stability of not any country is guaranteed over ages. Statements about theoretical safety of thousands or even millions of years are nonsense, because no organisation is safer than its management or the government of the relative country. The long term risk of nuclear fission therefore is extremely large. Nuclear fusion seems less dangerous, but insufficient knowledge is currently available for a sound assessment. The prospects of nuclear fission are also limited by its total costs including waste and plant dismantling and disposal. Availability of uranium is sufficient although economical high concentrations will be depleted sooner or later.
The International Atomic Energy Agency controls nuclear research and power plants.
A scientific assessment without emotions about nuclear energy is virtually impossible. This standard considers energy from nuclear fusion harmful to a similar extent as energy from combustion of mineral sources, if only because the preventive measures are the same, namely renewable energy sources.
