Techniques are described for management of high-level tritium-containing raffinate from NPP spent fuel reprocessing including its volume reduction by evaporation and the regeneration of recycled nitric acid, to adjust the still-pot solution for radionuclide partitioning. The questions on residue formation and acidity deminuation are discussed from the point of view of final volume of concentrate, as well as the conditions for production of final products: tritium-containing distillate to be discharged and regenerated nitric acid. A flowsheet for high-level waste management is proposed as a part of NPP spent fuel reprocessing with partitioning of radionuclides according to the degree of their toxicity.
