4、 Nā noi kikoʻī a me ka noiʻi patent koʻikoʻi o nā Element Rare Earth i nā mea nuklea
Ma waena o lākou, ʻoi aku ka ikaika o ka fusion nuklea a me ka nuclear fission reactions i nā mea nuklea, a paʻa nā koi no nā mea.I kēia manawa, ʻo nā reactors mana ka nui o ka nuclear fission reactors, a hiki ke hoʻolaha ʻia nā reactors fusion ma ke ʻano nui ma hope o 50 mau makahiki.ʻO ka noi ohonua lahanā mea i loko o nā mea hana reactor;Ma nā kahua kemika nukili, hoʻohana nui ʻia nā mea ʻene honua i nā koʻokoʻo mana;Kahi mea hou aʻe,scandiumua hoʻohana pū ʻia i ka radiochemistry a me ka ʻoihana nuklea.
（1） E like me ka lāʻau ʻawaʻawa a i ʻole ke koʻokoʻo mana e hoʻoponopono i ka pae neutron a me ke kūlana koʻikoʻi o ka reactor nuklea.
I nā reactors mana, ʻoi aku ka kiʻekiʻe o ke koena mua o nā cores hou.ʻOi aku i ka wā mua o ka pōʻaiapuni refueling mua, i ka wā e hou ai ka wahie nuklea i loko o ke kumu, ʻo ke koena reactivity ka mea kiʻekiʻe loa.I kēia manawa, ʻo ka hilinaʻi wale ʻana i ka hoʻonui ʻana i nā koʻokoʻo mana e hoʻopaʻi i ke koena o ka reactivity e hoʻokomo i nā koʻokoʻo mana.ʻO kēlā me kēia koʻokoʻo mana (a i ʻole pūʻolo koʻokoʻo) pili i ka hoʻokomo ʻana i kahi mīkini hoʻokele paʻakikī.Ma kekahiʻaoʻao, hoʻonui kēia i nā kumukūʻai, a ma kekahiʻaoʻao,ʻo ka weheʻana i nā puka i loko o ke poʻo o ka moku kaomi hiki ke alakaʻi i ka emiʻana o ka ikaika.ʻAʻole wale ia he mea waiwai ʻole, akā ʻaʻole ʻae ʻia ka loaʻa ʻana o kahi nui o ka porosity a me ka ikaika structural ma ke poʻo o ka moku kaomi.Eia nō naʻe, me ka ʻole o ka hoʻonui ʻana i nā koʻokoʻo mana, pono e hoʻonui i ka neʻe ʻana o nā mea hoʻopaʻi kemika (e like me ka boric acid) e uku ai i ke koena reactivity.I kēia hihia, he mea maʻalahi ka manaʻo o ka boron ma mua o ka paepae, a e lilo ka coefficient mahana o ka moderator i mea maikaʻi.
No ka pale ʻana i nā pilikia i ʻōlelo ʻia aʻe nei, hiki ke hoʻohana maʻamau ʻia ka hui ʻana o nā mea ʻawaʻawa, nā lāʻau hoʻomalu, a me ka mana hoʻopaʻi kemika.
（2） Ma ke ʻano he dopant e hoʻomaikaʻi ai i ka hana o nā mea hana reactor
Pono nā reactors i nā ʻāpana hana a me nā mea wahie e loaʻa i kahi pae o ka ikaika, ka pale ʻana i ka corrosion, a me ke kūpaʻa wela kiʻekiʻe, ʻoiai e pale ana i nā huahana fission mai ke komo ʻana i ka mea hoʻomaha.
1) .Ke kila kakaikahi
He kūlana kino a me kemika ko ka nuclear reactor, a loaʻa i kēlā me kēia ʻāpana o ka reactor nā koi kiʻekiʻe no ke kila kūikawā i hoʻohana ʻia.He hopena hoʻololi kūikawā ko nā ʻano honua ʻokoʻa ma ke kila, ʻo ia hoʻi me ka hoʻomaʻemaʻe, metamorphism, microalloying, a me ka hoʻomaikaʻi ʻana i ka pale ʻana i ka corrosion.Hoʻohana nui ʻia ka honua laʻa i loaʻa nā kila i nā reactor nuklea.
① Ka hopena hoʻomaʻemaʻe: Ua hōʻike ʻia ka noiʻi e kū nei he hopena maikaʻi ka hoʻomaʻemaʻe ʻana o ka honua laha i ke kila hoʻoheheʻe ʻia i nā wela kiʻekiʻe.ʻO kēia no ka mea hiki i nā honua laha ʻole ke hana me nā mea ʻino e like me ka oxygen a me ka sulfur i loko o ke kila hoʻoheheʻe e hana i nā pūhui wela kiʻekiʻe.Hiki ke hoʻokuʻuʻia a hoʻokuʻuʻia nā mea wela kiʻekiʻe ma keʻano o ka hoʻokomoʻana ma mua o ka hoʻoheheʻeʻiaʻana o ke kila i hoʻoheheʻeʻia, ma laila e ho'ēmi ai i ka mea haumia i loko o ke kila hoʻoheheʻe.
② Metamorphism: ma ka ʻaoʻao ʻē aʻe, hiki ke hoʻopaʻa ʻia nā oxides, sulfides a i ʻole oxysulfides e ka hopena o ka honua laʻa i loko o ke kila hoʻoheheʻe me nā mea ʻino e like me ka oxygen a me ka sulfur hiki ke hoʻopaʻa ʻia i loko o ke kila hehee a lilo i hoʻohui ʻia o ke kila me ka helu heheʻe kiʻekiʻe. .Hiki ke hoʻohana ʻia kēia mau inclusions e like me nā kikowaena nucleation heterogeneous i ka wā paʻa o ke kila hoʻoheheʻe ʻia, pēlā e hoʻomaikaʻi ai i ke ʻano a me ke ʻano o ke kila.
③ Microalloying: inā e hoʻonui hou ʻia ka hoʻohui ʻana o ka ʻāina laha ʻole, e hoʻoheheʻe ʻia ke koena o ka honua laha ʻole i ke kila ma hope o ka hoʻomaʻemaʻe ʻana a me ka metamorphism.No ka mea, ʻoi aku ka nui o ka radius atomic o ka honua laha ʻole ma mua o ka hao ʻātoma, ʻoi aku ka kiʻekiʻe o ka ʻoihana honua.I ka wā o ke kaʻina hana paʻa o ke kila hoʻoheheʻe ʻia, hoʻonui ʻia nā mea ʻenehana honua ma ka palena o ka palaoa, hiki ke hōʻemi maikaʻi i ka hoʻokaʻawale ʻana o nā mea haumia ma ka palena o ka palaoa, no laila e hoʻoikaika ai i ka hopena paʻa a pāʻani i ka hana o ka microalloying.Ma ka ʻaoʻao ʻē aʻe, ma muli o ke ʻano o ka mālama ʻana i ka hydrogen o ka honua laha, hiki iā lākou ke hoʻomoʻa i ka hydrogen i ke kila, a laila e hoʻomaikaʻi maikaʻi ai i ke ʻano hydrogen embrittlement o ke kila.
④ E hoʻomaikaʻi i ka pale ʻana i ka corrosion: ʻO ka hoʻohui ʻana i nā mea ʻenekele honua hiki ke hoʻomaikaʻi i ka pale ʻana o ke kila.ʻO kēia no ka mea, ʻoi aku ka ʻoi aku o ka ʻoi aku ka nui o ka pohō iā ia iho ma mua o ke kila kila.No laila, hiki i ka hoʻohui ʻana i nā ʻāina laha ʻole ke hoʻonui i ka pono corrosion ponoʻī o ke kila kila, a laila e hoʻomaikaʻi ai i ke kūpaʻa o ke kila i nā media corrosive.
