Molten fluoride salts incorporation into pristine and ion-modified carbon allotropes and metallic foils

Incorporation of molten fluoride salts into different carbon allotropes (gl assy carbon, pyrolytic graphite etc.) and metallic foils (Ni, Ti, etc.), pr istine and ion-treated substances, has been studied using non-destructive, depth sensitive nuclear analytical methods - Neutron Depth Profiling (NDP) and Rutherford Backscattering (RBS). Strong interaction between the molten LiF and LiF + KF + NaF salts and the tested materials was found. The result s are of great interest for accelerator driven transmutation technology (AD TT) which is a promising way towards effective liquidation of nuclear waste s.
