| Abstract: |
The paper describes experimental studies assessing the release of radionuclides into the gas phase from aqueous process media. These include simulators of solutions after clarification and dissolution of spent nuclear fuel (SNF) and re-extraction of transplutonium and rare earth elements. We propose algorithms for calculating the release of elements and its rate during the transition to the gas phase from simulant solutions. The dependence of the radionuclide release rate on the temperature, air flow, and composition of the process medium is shown. In terms of specific activity, strontium, cesium, cerium, ruthenium, europium, and technetium make the greatest contribution to the activity of the gas phase. [ABSTRACT FROM AUTHOR] |
