Abstract

In the present work, we investigated the isotopic replacement of deuterium with protium in EK‑181 steel under plasma irradiation. Samples were sequentially irradiated with deuterium and hydrogen plasma to a fluence of 1 × 1025 at/m2 at 473 K with a bias voltage of −100 V. Thermal desorption spectroscopy (TDS) analysis of the deuterium retention in the samples before and after exposure to H plasma showed that, after H plasma irradiation, the amount of deuterium, as determined from desorption of HD and D2 during the analysis, decreased by approximately a factor of 25. It is shown that protium‑for‑deuterium (H–D) isotopic exchange under plasma irradiation is a more effective method for removing deuterium from EK‑181 steel than vacuum annealing.
