The mention of nuclear energy brings to mind mushroom clouds and radiation-deformed species. It does not have to be that way; it is not that way at all. Nuclear energy has made and continues to make significant positive contributions to our lives from generation of electricity to applications in science and industry and, maybe the most important of all, medical diagnosis and therapy. No human activity is without some undesirable effects and nuclear energy is no exception. In the process of fissioning the nucleus we generate radiaocative materials that must be safeguarded for many many years. Technically sound ways to take care of these radiocative substances will be discussed. Of course we worry about radiaoactive wastes because we are afraid of radiation, and we should be. But, for this matter too, factual informatioon will help alleviate the fear. Is nuclear energy renewable? Not in the "traditional" sense.But, one should consider the following. One, the fuels used (U and Th)do not have any other use. Two, the burning of U or Th produces new fuels , Pu-239 and U-233 that can be used for continuous generation of electricity or production of radaioisotopes that may be used in industry and medicine.
