Approbation of a New Ion-Plasma Technology for Reactor Graphite Deactivation
https://doi.org/10.56304/S2079562922050359
Abstract
A fundamentally new approach for the deactivation of irradiated reactor graphite and metal structures of nuclear power plants is proposed, that is “dry” ion-plasma deactivation technology based on the interdisciplinary approach. The technology includes sputtering of a surface radioactive layer by fast ions of micro-plasma discharge in an inert gas under atmospheric pressure with mass transfer in the diffusion mode and condensation of the sputtered material into the replaceable collector anode. The experimental approbation of ion-plasma technology was carried out using samples of reactor graphite grade GR-280 and optimal operating parameters were obtained.
