Estimation of the time to achieve radiation and radiological equivalence of radioactive waste and natural uranium raw material in full replacement of thermal reactors by fast reactors in 2130

The article estimates the time required to achieve radiation and radiological equivalence between radioactive waste and natural uranium raw materials, assuming that all thermal reactors will be fully replaced by fast reactors by the year 2130. Radiation equivalence will be reached when the carcinogenic risks of radioactive waste and natural raw uranium have the same value according to effective dose technologies. The estimated time required for this radiation equivalence is 250 years. Additionally, radiological equivalence can also be achieved if the carcinogenic risk associated with radioactive waste and raw natural uranium has the same values as those of lifetime attributable risk (LAR) technologies. The estimated potential time for this radiological equivalence is 78 years. Furthermore, the potential time for the burial of radioactive waste is also considered. It is estimated that this event will occur after the year 2208.
