Influence of high-energy particles on copper and stainless steel in fusion reactor materials

Abstract

Many studies were focused on the effect of fusion plasma particles onto the structural materials of future nuclear fusion reactor. In this paper, the effect of the products of the first generation fuel reaction on structural fusion materials as copper and 316-stainless steel target materials was studied. Firstly, the effect of 14.1 MeV neutrons produced from D-T neutron generator for different irradiation time equal to 10, 20, 30, 50 and 60 minutes was investigated. Hence, this effect was analyzed and characterized by X-ray diffration analysis, surface roughness tester, scanning electron microscope and Vickers hardness. Secondly, the effect of 3.5 MeV α-particles on these target materials by different incident angles equal to 0°, 30°, 45°, 60° and 85° using SRIM code was studied. Also, SRIM code was used for calculation α-particles trajectories, projected and straggle ranges, skewness, kurtosis, target ionization / phonons and total displacements for copper and 316- stainless steel target materials.

Effect of 14.7 MeV Protons on Beryllium Micro Brush / Copper ITER First Wall using SRIM

“…As in most implantation processes the extension of the implanted area is very large compared to the ion range, Rp is mostly also the only range quantity which is accessible to measurement. In the previous our studies about the plasma facing components used in future nuclear fusion reactor, we discussed the effect of particles produced from the 1 st generation fusion fuel reaction (14.1 MeV neutrons) on some structural fusion materials as graphite, tungsten, 316-stainless steel and copper experimentally using D-T neutron generator with different irradiation time [19], [20]. Then, we simulate the effect of the released particles from the 2 nd generation of fusion reaction (3.6 MeV α-particles and 14.7 MeV protons) on fusion materials as graphite, zirconium, titanium, tantalum, molybdenum and tungsten [21].…”

“…The displacements of interplanar spacing in copper is studied for α-particles and neutrons in [ 14 ]. The grain size effect on the radiation damage tolerance of cubic zirconia in low and high energy heavy ions is investigated by Radwan and El-Khabeary [ 15 ]. The erosion effect of neutral particles has been studied for the Experimental Advanced Superconducting Tokamak by Mu et al [ 16 ].…”
