IHeliumidlala indima ebalulekileyo kuphando nakuphuhliso kummandla wokudibanisa kwenyukliya. Iprojekthi ye-ITER kwichweba laseRhône eFransi sisixhobo sokwenza umxube we-thermonuclear esisakhiwayo. Le projekthi iza kuseka umzi-mveliso wokupholisa ukuqinisekisa ukupholisa kwesixhobo sombane. "Ukuze kuveliswe amasimi e-electromagnetic ayimfuneko ukujikeleza i-reactor, i-superconducting magnetic materials iyafuneka, kunye ne-superconducting magnetic materials kufuneka isebenze kumaqondo obushushu aphantsi kakhulu, kufutshane ne-zero ngokupheleleyo." Kwisityalo sokupholisa se-ITER, indawo yesityalo se-helium ithatha indawo ye-3,000 square metres, kwaye indawo yonke ifikelela kwi-5,400 square metres.
Kumalinge okudibanisa inyukliya,i-heliumisetyenziswa kakhulu kwifriji kunye nomsebenzi wokupholisa.IHeliumithathwa njengefriji efanelekileyo ngenxa yeempawu zayo ze-cryogenic kunye nokuhamba kakuhle kwe-thermal. Kwisityalo sokupholisa se-ITER,i-heliumisetyenziselwa ukugcina i-reactor kubushushu obuchanekileyo bokusebenza ukuqinisekisa ukuba inokusebenza ngokufanelekileyo kwaye ivelise amandla okudibanisa okwaneleyo.
Ukuqinisekisa ukusebenza okuqhelekileyo kwe-reactor, isityalo sokupholisa sisebenzisa izixhobo zemagneti e-superconducting ukuvelisa intsimi ye-electromagnetic efunekayo. Iimathiriyeli zemagnethi ezisebenza kakhulu kufuneka zisebenze kumaqondo obushushu aphantsi kakhulu, kufutshane ne-zero ngokupheleleyo, kwiipropathi ezifanelekileyo ze-superconducting. Njengomthombo obalulekileyo wefriji,i-heliuminokubonelela ngemekobume efunekayo yobushushu obuphantsi kwaye ipholise ngokufanelekileyo i-superconducting magnetic material ukuqinisekisa ukuba inokufikelela kwimeko yokusebenza elindelekileyo.
Ukuze kuhlangatyezwane neemfuno zesityalo sokupholisa i-ITER, ii-heliumisityalo sithatha indawo enkulu. Oku kubonisa ukubaluleka kwe-helium kuphando lwenyukliya edityanisiweyo kunye nophuhliso, kunye nokubaluleka kwayo ekuboneleleni ngemekobume efunekayo ye-cryogenic kunye nesiphumo sokupholisa.
Ukuququmbela,i-heliumidlala indima ebalulekileyo kuphando lwenyukliya edityanisiweyo nophuhliso. Njengesixhobo sokukhenkcisa esifanelekileyo, sisetyenziswa kakhulu kumsebenzi wokupholisa wezixhobo zokulinga zenyukliya zokudibanisa. Kwisityalo sokupholisa se-ITER, ukubaluleka kwe-helium kubonakala kumandla ayo okubonelela ngemeko efunekayo yobushushu obuphantsi kunye nesiphumo sokupholisa ukuqinisekisa ukuba i-reactor inokusebenza ngokuqhelekileyo kwaye ivelise amandla okudibanisa okwaneleyo. Ngophuhliso lobuchwepheshe bokudibanisa inyukliya, ithemba lokusetyenziswa kwe-helium kummandla wophando nophuhliso liya kuba banzi.
