Fabrication of nano-micro-sized 14C enriched constructive elements in plasma deactivation treatment of irradiated reactor graphite
Year: 2020
Type: conference-paper
Abstract: We propose a new fabrication method for the meta-material said "beta-active nano-sandwich" (for example, enriched with radioisotope 14C, etc.) by a plasma sputtering technology that we are developing for the decontamination of nuclear power plants constructions. This new kind of beta-active nano-materials can be a valuable product resulting from nuclear deactivation process and be useful for nuclear medicine applications and creation of advanced beta-voltaic batteries. Plasma sputtering device operation is based on a “dry” plasma decontamination method – the ion sputtering of radionuclides from the radioactively polluted surface (e.g., irradiated reactor graphite). We present calculations results of the plasma sputtering device operating parameters: anode and cathode surface temperature, discharge input power density, equivalent current density, ion sputtering and mass-transfer rates of nano - layers from the processed graphite surface.
