Conditions for Reaching Radiation Equivalence of Native Raw Materials and Long-Lived Radioactive Waste in Nuclear Energy in Russia

The basic requirements of regeneration of spent fuel from BREST reactors in order to reach radiation equivalence in the nuclear energy system are presented. It is shown on the basis of computational modeling of scenarios for the development and long-term operation of the nuclear energy system, including nuclear power plants with thermal and fast reactors, that radiation equivalence of waste and natural uranium can be reached. At the same time, the requirements of radiochemical technology also extend to the reprocessing of spent fuel from thermal reactors. The effect of the content of actinides and fission products in the waste on the hold-up period to reach radiation equivalence is shown.
