These simulations explained the different response of pre-damaged W with different grain sizes to D irradiation. We also predicted the effect of limited D surface recombination (due to C) on enhanced D retention in bulk and in voids with increasing irradiation temperatures. Increasing damage level (dpa) causes a transition from preferential D trapping in low-energy traps to more voids/bubbles production and growth. Irradiation conditions and temperature variation during and between discharges is critical for hydrogen isotopes accumulation in PFMs.
