▁enough ▁to ▁make ▁a ▁commercial ▁power ▁station ▁econom ically ▁vi able ▁in ▁the ▁presence ▁of ▁the ▁inten se ▁neut ron ▁bomb ard ment . ▁The ▁damage ▁is ▁primarily ▁caused ▁by ▁high ▁energy ▁neut rons ▁knock ing ▁atoms ▁out ▁of ▁their ▁normal ▁position ▁in ▁the ▁cry stal ▁lattice . ▁A ▁related ▁problem ▁for ▁a ▁future ▁commercial ▁fusion ▁power ▁station ▁is ▁that ▁the ▁neut ron ▁bomb ard ment ▁will ▁indu ce ▁radio activity ▁in ▁the ▁re actor ▁material ▁itself . ▁M aint aining ▁and ▁de comm ission ing ▁a ▁commercial ▁re actor ▁may ▁thus ▁be ▁difficult ▁and ▁expensive . ▁Another ▁problem ▁is ▁that ▁super con duct ing ▁magnet s ▁are ▁dam aged ▁by ▁neut ron ▁flux es . ▁A ▁new ▁special ▁research ▁facility , ▁IF M IF , ▁is ▁planned ▁to ▁investigate ▁this ▁problem . ▁ ▁Another ▁source ▁of ▁concern ▁comes ▁from ▁the ▁ 2 0 1 3 ▁to k am ak ▁parameters ▁database ▁interpolation ▁which ▁says ▁that ▁power ▁load ▁on ▁to k am ak ▁di vert ors ▁will ▁be ▁five ▁times ▁the ▁previously ▁expected ▁value ▁for ▁I TER ▁and ▁much ▁more ▁for ▁actual ▁electric ity - gener ating ▁react ors . ▁Given ▁that ▁the ▁project ed ▁power ▁load ▁on ▁the ▁I TER ▁di vert or ▁is ▁already ▁very ▁high , ▁these ▁new ▁find ings ▁mean ▁that ▁new ▁di vert or ▁designs ▁should ▁be ▁ur g ently ▁tested . ▁However , ▁the ▁corresponding ▁test ▁facility ▁( AD X ) ▁has ▁not ▁received ▁any ▁fund ing ▁. ▁ ▁A ▁number ▁of ▁fusion ▁research ers ▁working ▁on
