Abstract: FIELD: technological processes. 
     SUBSTANCE: invention relates to radiochemical technology. Method of selective extraction of radionuclides from nitric acid solutions involves reduction treatment of initial solution, contacting with extractant consisting of solution of aliphatic hydroxamic acid C 8 -C 10  in hydrophobic liquid alcohols, combined extraction of molybdenum and zirconium nuclides with extract thereof with their purification from uranium, washing of the extract with a solution of nitric acid and separation of radionuclides jointly or separately from the extract during its thermal treatment or by re-extraction into an alkaline solution. Extraction into solutions of aliphatic alcohols C 8 -C 10  with saturated hydrocarbons and extract washing is carried out with addition of a strong reducing agent. Re-extraction of Mo with Zr is carried out in solution of nitric acid by thermochemical oxidation of hydroxamic acid in extract. Destructible complexing agent concentrate is added to the re-extract, and phosphoric acid is washed out with an alkaline solution in proportions providing washing the zirconium alkylphosphate complex from the aqueous solution of molybdenum. 
     EFFECT: invention enables to develop a universal method of selective removal of zirconium and molybdenum at the re-extraction step with their deep purification from alpha and gamma-emitting nuclides.

Arcs are fed continuously from two power supplies with heteropolar current pulses with pulse frequency of not less than 50 Hz. Ratio of duration of flow of current of direct polarity to non-consumable electrode is selected within 0.8–0.6 of period of the first power supply source, which provides both destruction of aluminium oxide film on article and resistance of electrode. Value of pulses to non-consumable electrode is selected based on maximum allowable currents of direct and reverse polarity in single-arc welding at direct current. Ratio of duration of flow of direct polarity current to melted electrode is selected within 0.8–0.4 of period of the second power supply. This provides higher rate of electrode melting in 1.5…2.0 times compared to reversed polarity arc welding.
