“…Demonstrations in current tokamaks are important to demonstrate that the released tritium is recoverable and there are no reactive radicals that could be reabsorbed before exiting the torus. Debris produced by ablative methods will need to be efficiently collected [47]. The merits and shortcomings of several techniques are listed in Table II.…”

“…The contaminants at a deeper depth are removable when irradiated by a laser, but this has resulted in surface ablation. 2 Previous research has also shown an enhancement in cesium at the surface when irradiated by a laser. 3 Thus, the main goal of this project was to find the optimal laser parameters that would enhance metal contaminant redistribution on a mineral oxide matrix in a non-destructive manner.…”

“…A large number of pulses introduces structural modifications and precipitations. This microstructural alteration due to the laser modifies the properties of the oxide [5][6][7][8]. In addition, the profile of the content of radionuclides bound to the oxide are higher near the oxidized outer surface, this greater content is due to its solubility and its low diffusibility.…”

The destruction of the passive oxide can be caused by the action of a radionuclide, which collides with the surface of the oxide. In this case, the β− nuclear particle produced by the decay of tritiated water is considered for corrosion, and it follows that the β− energy is absorbed first into the oxide. The penetration depth is sufficient for all the passive oxides to be destabilized. Destabilization was examined by voltammetry and by the electrochemical circuit in the passive potential. The corresponding pathway leads to the destruction of oxide. Tests carried out using a chaos data analyzer are an aid for expertise. Different behavior may occur depending on the passive potential and the β− density. The synchronization of phase space spectra and tests realized sector by sector make possible the interpretation of divergence leading to unstable oxide and oxide destruction at different passive potentials and for different β− particle densities.
