The　high　energetic　particle　generated　from　nuclear　fusion　will　severely　change　material　structures　and　properties　of　the　reactor,　where　the　surface　of　the　steering　gear　would　become　fluffy.　On　this　basis,　the　SRIM　software　is　introduced　in　this　paper,　aiming　to　investigate　the　impact　of　different　ions　with　different　masses　and　energies　on　material　structures　in　order　to　observe　the　damage　on　the　material　caused　by　the　radiation.　According　to　our　simulation,　a　drop　in　13%　elastic　property　has　been　observed.　The　bombardment　can　produce　a　considerable　amount　of　damage,　which　should　be　taken　into　consideration　during　the　design.　Thus,　the　tungsten　shield　can＇t　be　used　as　weight　supporting　element.　Besides,　regarding　the　above　discussion,　a　wider　margin　should　be　taken　into　consider　when　designing　the　fusion　reactor.　We　hope　to　figure　out　some　uncontrollable　error　and　imperfection　still　existing　in　the　simulation.　These　results　offer　a　guideline　for　better　observation　of　the　damage　on　the　material　caused　by　the　radiation.　©　2022　SPIE.
