1、 Inkcazelo yeMathiriyeli yeNyukliya
Kwingqiqo ebanzi, imathiriyeli yenyukliya ligama eliqhelekileyo lezinto ezisetyenziswa ngokukodwa kushishino lwenyukliya nophando lwenzululwazi yenyukliya, kubandakanywa amafutha enyukliya kunye nemathiriyeli yobunjineli benyukliya, okt imathiriyeli engeyiyo inyukliya yamafutha.
Izinto eziqhele ukubhekiswa kwizixhobo zenyukliya ikakhulu zibhekisa kwimathiriyeli esetyenziswa kwiindawo ezahlukeneyo zereactor, ekwaziwa njengemathiriyeli yereactor.Imathiriyeli ye-reactor iquka amafutha enyukliya athi atyhutyhe inyutroni phantsi kwebhombu yenyutroni, imathiriyeli yokugquma yamalungu enutroni yamafutha enyukliya, izinto zokupholisa, iimodareyitha zeneutron (iimodareyitha), izixhobo zokulawula intonga ezifunxa ngamandla iinutroni, kunye nemathiriyeli ekhanyayo ethintela ukuvuza kwenyutroni ngaphandle kwereactor.
2, Ubudlelwane obunxulumeneyo phakathi kobutyebi bomhlaba obunqabileyo kunye nezixhobo zenyukliya
I-Monazite, ekwabizwa ngokuba yi-phosphocerite kunye ne-phosphocerite, iyindawo eqhelekileyo yeeminerali kwi-acid ephakathi igneous rock kunye nelitye le-metamorphic.IMonazite yenye yeeminerali eziphambili zentsimbi enqabileyo yomhlaba, kwaye ikhona nakwelinye iliwa lentlenga.I-Brown ebomvu, etyheli, ngamanye amaxesha i-brownish yellow, kunye ne-luster enamafutha, i-cleavage epheleleyo, ubunzima be-Mohs ye-5-5.5, kunye nobunzima obuthile be-4.9-5.5.
Iminerali engundoqo yolunye uhlobo lwe-placer idiphozithi zomhlaba ezinqabileyo e-China yi-monazite, ikakhulu ibekwe e-Tongcheng, e-Hubei, e-Yueyang, e-Hunan, e-Shangrao, e-Jiangxi, e-Menghai, e-Yunnan, nase-He County, e-Guangxi.Nangona kunjalo, ukutsalwa kohlobo lwe-placer ubutyebi bomhlaba obunqabileyo kaninzi alubalulekanga ngokwezoqoqosho.Amatye odwa ahlala equlathe izinto ze-thorium eziguqukayo kwaye zikwangowona mthombo uphambili weplutonium yorhwebo.
3、 Isishwankathelo sosetyenziso lomhlaba olunqabileyo kumxube wenyukliya kunye nokuqhekeka kwenyukliya okusekwe kuhlalutyo lwepatent panorama
Emva kokuba amagama angundoqo ezinto ezinqabileyo zokukhangela umhlaba andiwe ngokupheleleyo, adityaniswa nezitshixo zokwandisa kunye namanani okuhlelwa kwe-fission yenyukliya kunye ne-nyukliya fusion, kwaye zikhangelwe kwi-database ye-Incopt.Umhla wokukhangela ngumhla wama-24 ka-Agasti 2020. Amalungelo awodwa omenzi wechiza angama-4837 afunyenwe emva kokudityaniswa okulula kosapho, kwaye amalungelo awodwa omenzi wechiza angama-4673 amiselwa emva kokunciphisa ingxolo eyenziweyo.
Ukusetyenziswa kwelungelo elilodwa lomenzi wechiza emhlabeni kummandla wokuqhekeka kwenyukliya okanye ukudityaniswa kwenyukliya zisasazwa kumazwe/iingingqi ezingama-56, ingakumbi eJapan, eTshayina, eUnited States, eJamani naseRussia, njl. njl. , apho izicelo zeteknoloji ye-patent yaseTshayina ziye zanda, ngakumbi ukususela ngo-2009, zingena kwinqanaba lokukhula ngokukhawuleza, kwaye iJapan, i-United States kunye neRashiya ziye zaqhubeka nokucwangcisa kule ntsimi iminyaka emininzi (Umfanekiso 1).
Umfanekiso 1 Indlela yokusetyenziswa kwelungelo elilodwa lomenzi wechiza elinxulumene nosetyenziso lomhlaba olunqabileyo kwinyukliya yokuqhekeka kunye nokudityaniswa kwenyukliya kumazwe/kwiingingqi.
Inokubonwa kuhlalutyo lwemixholo yobugcisa ukuba ukusetyenziswa komhlaba onqabileyo kumxube wenyukliya kunye nokuqhekeka kwenyukliya kugxininise kwizinto zamafutha, iiscintillators, i-radiation detectors, ii-actinides, iiplasma, izixhobo zenyukliya, izixhobo ezikhuselayo, ukufunxa inyutroni kunye nolunye ulwalathiso lobugcisa.
4, Ukusetyenziswa okuKhethekileyo kunye noPhando oluPhambili lwePatent yeZiqalelo zoMhlaba eziRare kwiiMathiriyeli zeNyukliya
Phakathi kwazo, ukudityaniswa kwenyukliya kunye nokuqhekeka kwenyukliya kwizixhobo zenyukliya kunamandla, kwaye iimfuno zemathiriyeli zingqongqo.Okwangoku, izixhobo zokuvelisa amandla ngokuyintloko ziziizixhobo zenyukliya zokuqhekeka, kwaye ii-reactors ezidityanisiweyo zinokusasazwa ngomlinganiselo omkhulu emva kweminyaka engama-50.Ukusetyenziswa kweumhlaba onqabileyoizinto kwimathiriyeli yesakhiwo sereactor;Kwiindawo ezithile zeekhemikhali zenyukliya, izinto zomhlaba ezinqabileyo zisetyenziswa ikakhulu kwiintonga zokulawula;Ukwengeza,scandiumiye yasetyenziswa nakwi-radiochemistry nakwishishini lenyukliya.
(1) Njengetyhefu etshayo okanye intonga yokulawula ukulungisa inqanaba le-neutron kunye nemeko ebalulekileyo yereactor yenyukliya.
Kwiireactors zamandla, intsalela yokuphinda isebenze kwakhona kweecores ezintsha iphezulu kakhulu.Ngokukodwa kwizigaba zokuqala zomjikelo wokuqala wokugalela i-refueling, xa zonke izibaso zenyukliya zisembindini zintsha, ukuphinda kusebenze kwakhona kuphezulu.Ngeli xesha, ukuthembela kuphela ekwandeni kweentonga zolawulo ukuhlawulela ukuphinda kusebenze kwakhona kungazisa iinduku zolawulo ezongezelelekileyo.Intonga nganye yokulawula (okanye inyanda yentonga) ihambelana nokuqaliswa kwendlela yokuqhuba eyinkimbinkimbi.Ngakolunye uhlangothi, oku kwandisa iindleko, kwaye ngakolunye uhlangothi, ukuvula imingxuma kwintloko yenqanawa yoxinzelelo kunokukhokelela ekunciphiseni amandla okwakhiwa.Akukona nje ukungabikho kwezoqoqosho, kodwa akuvumelekanga ukuba nenani elithile le-porosity kunye namandla okwakhiwa kwintloko yenqanawa yoxinzelelo.Nangona kunjalo, ngaphandle kokunyuswa kweentonga zokulawula, kuyimfuneko ukwandisa ukuxinwa kweekhemikhali zokuhlawula i-toxins (ezifana ne-boric acid) ukuhlawulela ukuphinda kusebenze.Kule meko, kulula ukuba ugxininiso lwe-boron lugqithise umqobo, kwaye i-coefficient yokushisa yomodareyitha iya kuba yinto enhle.
Ukuphepha ezi ngxaki zikhankanywe ngasentla, indibaniselwano yeetyhefu ezivuthayo, iinduku zokulawula, kunye nolawulo lwembuyekezo yemichiza ngokubanzi zinokusetyenziswa ukulawula.
(2) Njengedopant yokuphucula ukusebenza kwezixhobo zolwakhiwo lwereactor
Iireactors zifuna iinxalenye zesakhiwo kunye ne-fuel element ukuba zibe nenqanaba elithile lamandla, ukuxhathisa ku-corrosion, kunye nozinzo oluphezulu lwe-thermal, ngelixa zikwathintela iimveliso zokuqhekeka ekungeneni kwesipholisi.
1) .Intsimbi yomhlaba enqabileyo
Isixhobo senyukliya sineemeko ezigqithisileyo zomzimba nezekhemikhali, kwaye inxalenye nganye yereactor nayo ineemfuno eziphezulu zentsimbi ekhethekileyo esetyenziswayo.Izinto ezinqabileyo zomhlaba zineempembelelo ezikhethekileyo zokuguqulwa kwentsimbi, ngakumbi kubandakanya ukucocwa, i-metamorphism, i-microalloying, kunye nokuphuculwa kokuxhathisa ukubola.Umhlaba onqabileyo oqulethe iintsimbi nawo usetyenziswa kakhulu kwizixhobo zenyukliya.
① Isiphumo sokucoca: Uphando olukhoyo lubonise ukuba umhlaba onqabileyo unesiphumo esihle sokucoca kwintsimbi etyhidiweyo kumaqondo obushushu aphezulu.Oku kungenxa yokuba umhlaba onqabileyo unokusabela ngezinto ezinobungozi ezifana neoksijini kunye nesalfure kwintsimbi etyhidiweyo ukuvelisa iikhompawundi zobushushu obuphezulu.Izixhobo ezinobushushu obuphezulu zinokuthi zihlanjululwe kwaye zikhutshwe ngendlela yokufakwa phambi kokuba insimbi etyhidiweyo idibanise, ngaloo ndlela inciphisa umxholo wokungcola kwintsimbi etyhidiweyo.
② I-Metamorphism: kwelinye icala, i-oxides, i-sulfides okanye i-oxysulfides eveliswa kukusabela komhlaba onqabileyo kwintsimbi etyhidiweyo enezinto ezinobungozi ezifana ne-oksijini kunye nesulfure inokugcinwa ngokuyinxenye kwintsimbi etyhidiweyo kwaye ibe yintsimbi enendawo ephezulu yokunyibilika. .Ezi zibandakanya zingasetyenziselwa njengamaziko e-nucleation ahlukeneyo ngexesha lokuqiniswa kwensimbi etyhidiweyo, ngaloo ndlela kuphuculwe ubume kunye nesakhiwo sensimbi.
③ I-Microalloying: ukuba ukongezwa komhlaba onqabileyo kuye kwandiswa ngakumbi, umhlaba onqabileyo oseleyo uya kuchithwa kwintsimbi emva kokuhlanjululwa okungentla kunye ne-metamorphism.Kuba iradiyasi yeathom yomhlaba enqabileyo inkulu kuneathom yentsimbi, umhlaba onqabileyo unomsebenzi ophezulu womphezulu.Ngethuba lenkqubo yokuqinisa intsimbi etyhidiweyo, izinto ezinqabileyo zomhlaba zityetyiswa kumda wengqolowa, ezinokuthi zinciphise kangcono ukuhlukana kwezinto ezingcolileyo kumda wengqolowa, ngaloo ndlela ukuqinisa isisombululo esiqinileyo kunye nokudlala indima ye-microalloying.Kwelinye icala, ngenxa yeempawu zokugcina i-hydrogen zomhlaba ezinqabileyo, zinokufunxa i-hydrogen kwintsimbi, ngaloo ndlela iphucula ngempumelelo i-hydrogen embrittlement phenomenon yentsimbi.
④ Ukuphucula ukuxhathisa kwe-corrosion: Ukongezwa kwezinto ezinqabileyo zomhlaba nako kunokuphucula ukuxhathisa kwentsimbi.Oku kungenxa yokuba imihlaba enqabileyo inamandla aphezulu wokuzidla kunentsimbi engatyiwayo.Ke ngoko, ukongezwa kwemihlaba enqabileyo kunokonyusa amandla e-self corrosion yensimbi engenasici, ngaloo ndlela kuphuculwe uzinzo lwentsimbi kwimithombo yeendaba ezonakalisayo.
2).Uphononongo lwePatent engundoqo
