 Under conservative assumptions, the total hydrogen inventory (deuterium and tritium) was found to be well below the ITER tritium safety limit, reaching $\approx \SI{14}{g}$ after 25 000 pulses of \SI{400}{s}.
 
 To investigate the influence of helium exposure on these results, a helium bubble growth model was developed.
-The results of this helium growth model were in good aggreement with published numerical results and experimental observations.
+The results of this helium growth model were in good agreement with published numerical results and experimental observations.
 A parametric study was performed to investigate the influence of exposure conditions on the bubbles density and size.
-To investigate the influence of helium bubbles on hydrogen transport, deuterium TDS experiments of tungten pre-damaged with helium were then reproduced.
+To investigate the influence of helium bubbles on hydrogen transport, deuterium TDS experiments of tungsten pre-damaged with helium were then reproduced.
 The distribution of bubbles density and size was computed using this helium bubble growth model and the results were used in FESTIM simulations.
 It was found that exposing tungsten to helium could potentially reduce the hydrogen inventory by saturating defects, making it impossible for hydrogen to get trapped.
 Moreover, the effect of helium bubbles (creation of additional traps for hydrogen) is limited to the near surface region (small compared to the monoblock's scale)
