In 1995, 32,200 metric tons of spent fuel with a total activity of 30,200 MCi were stored by the electric utilities at 70 sites (either in pools or in dry storage systems) (2, 4).By 2020, the projected inventory will be 77,100 metric tons of heavy metal (MTHM) with a total activity of 34,600 MCi.Igneous incursions into sedimentary layers can be dated using Uranium decay. Again small changes in the amount of Uranium or the amount of Lead can lead to large differences in the estimated age of the igneous layers.Also the calculation are based on assumptions that the layer started with no lead and 100% uranium and no erosion has occurred.
Radioactive dating then can only be used to generally support the theory of evolution.
The estimated cost of remediation and restoration actives in the Department of Energy complex during the next decades is in the order of 200 billion dollars (3).
Just over 20 percent of the electricity generated in the United States is produced by nuclear power reactors.
In fact, the need for safeguards to protect against the diversion of separated plutonium applies equally to all grades of plutonium (10).
The peaceful use of nuclear energy will inevitably require a strategy for the disposition and disposal of actinides.
Np) are long-lived, they have a major impact on risk assessments of geologic repositories.
