Deuterium retention and ammonia production from D-implanted 316 L stainless steel: insights for future fusion reactors
Abstract
<jats:title>Abstract</jats:title><jats:p>We present a systematic study that quantifies deuterium (D) retention and ammonia (ND<jats:sub>3</jats:sub>) production from 316 L stainless steel (SS316L) following the implantation of D ions in conditions similar to the ones expected in the ITER tokamak, i.e. with kinetic energy below 300 eV. Using Temperature Programmed Desorption (TPD) after deuterium ion implantation at 250 eV/D, we show that deuterium retention increases linearly with the D fluence up to 10<jats:sup>21</jats:sup> D<jats:sup>+</jats:sup>m<jats:sup>−2</jats:sup>, with a retention probability of 18%. For higher D fluence, deuterium retention increases sub-linearly. Analysis of the TPD spectra evolution with varying storage time in vacuum after D implantation, shows that D retention is influenced by D diffusion into the bulk of SS316L. Subsequent to D ion implantation, we evidence the efficient production of ND<jats:sub>3</jats:sub> molecules during TPD, between 400 K and 750 K, from the nitrogen present naturally in SS316L. Up to 21% of the D release during TPD can be found in ND<jats:sub>3</jats:sub> molecules, indeed. The fraction of ND<jats:sub>3</jats:sub> in the total D release depends both on the D ion fluence and the nitrogen concentration profile in the bulk. At least 7% of the D release is found in the form of ND<jats:sub>3</jats:sub> molecules, even at a fluence of 2 × 10<jats:sup>21</jats:sup> D<jats:sup>+</jats:sup>m<jats:sup>−2</jats:sup> and for a natural N concentration bulk profile. Both N diffusion and D diffusion into the bulk appear to dictate the kinetics of ND<jats:sub>3</jats:sub> production. Our findings of efficient production of ND<jats:sub>3</jats:sub> in D-implanted austenitic 316 L stainless steel underline the need for similar studies on reduced-activation ferritic/martensitic (RAFM) steels that contain similar content of nitrogen and will be used in fusion reactor prototypes.</jats:p>
