Uhlobo lwe-Y Uhlobo lwesihluzi soLiquid uHlahlelo lwaMasuntswana aqulathe ii-Alpha Emitters kuManzi afileyo kwiReactor Annnular Chamber of Unit 2 yeFukushima Daiichi Nuclear Power Plant

Enkosi ngotyelelo lwakho https://likvchina.goodao.net/, usebenzisa uguqulelo lwenkxaso yebrawuza yeCSS co., LTD. Ngowona mava angcono, sicebisa ukuba usebenzise isikhangeli esitsha (okanye ucime imo yokuhambelana kwi-Internet Explorer). Okwangoku, ukuqinisekisa inkxaso eqhubekayo, siya kubonisa isayithi ngaphandle kwezitayela kunye neJavaScript. Amacandelo aqulethe i-alpha (α) nuclides afunyenwe kwintlenga kumanzi ajikelezayo e-reactor no. 2 ye-Fukushima Daiichi Nuclear Power Plant (FDiNPS). I-Uranium (U), eyona nxalenye iphambili yamafutha enyukliya, yahlalutywa ngokuskena i-electron microscope (SEM). Ezinye i-α -nuclides (i-plutonium [Pu], i-americium [Am] kunye neCurium [Cm]) zifunyenwe yi-α locus, kunye ne-morphology ye-α -nuclide particles yahlalutywa yi-SEM energy spectrum analysis (EDX). Amasuntswana aliqela e-uranium ukusuka kwi-submicron ukuya kwi-microns ezininzi afunyenwe ngokuskena i-electron microscopy. Ezi ngqungquthela ziqulethe i-zirconium (i-Zr) kunye nezinye izinto ezenza i-fuel cladding kunye nezinto zokwakha. Umlinganiselo we-235U/238U we-isotope kwiqhezu eliqinileyo (kuquka amasuntswana e-U) uyahambelana namafutha enyukliya afunyenwe kwi-reactor no. 2. Oku kubonisa ukuba i-uranium yokwakheka kwamafutha afanayo iba ngcono. Amalungu aqulathe ii-nuclides ezichongiweyo luhlalutyo lwe-alpha trajectory lususela kumashumi ukuya kumakhulu eemicrons. Uhlalutyo lwe-EDX lwe-spectroscopic lubonisa ukuba la maqhekeza aqulethe i-iron. I-Pu, i-Am kunye ne-Cm i-adsorbed kwi-Fe particles ngenxa yexabiso elincinci le-α -nuclide. Olu phononongo lucacisa iiyantlukwano kwiintlobo eziphambili ze-U kunye nezinye ze-alpha nuclides kwi-hydroponic deposits ye-annular chamber ye-FDiNPS 2 reactor. I-Tepco's Fukushima Daiichi iplanti yamandla enyukliya (FDiNPS) yonakaliswe kakhulu yinyikima kaMatshi 11, 2011 kunye netsunami eyalandelayo. Ngelo xesha, iiyunithi 1-3 ze-reactors ezintandathu zazisebenza, kwaye i-fuel yenyukliya kwiiyunithi ze-1-3 zonakaliswe. Amanzi olwandle kunye namanzi amatsha atofwa ukususa ubushushu obubolileyo kumafutha enyukliya. Amanzi ahlala kwindawo engaphantsi kwesakhiwo, apho iinxalenye zamafutha enyukliya zinyibilika, nto leyo edala idama lokusasazeka ngemitha elinamandla kakhulu lamanzi. Amanzi afileyo aqulethe i-radionuclides efana neemveliso ze-fission kunye ne-nuclear fuel actinides. Ukuseka inkqubo yonyango lwemichiza yokususa iiradionuclides, ukuseka inkqubo yobunjineli bokujikeleza, kunye nokubuyisela amanzi okupholisa ukuze aphinde asetyenziswe. Ukusukela ngoko, umyinge wamanzi amileyo uye wehla kancinci kancinci, kodwa amasuntswana amahle aqulathe ukugxilwa okuphezulu kwealpha (α) radionuclides afunyenwe ngaphantsi komhlaba kwizakhiwo zereactor. Ugxininiso lwealpha nuclides (102-105 Bq/L) emanzini amileyo, kuquka nentlenga, luphezulu kunamanzi apholisayo kwizakhiwo ezisezantsi. Iradiated radionuclides, njenge-uranium (U) kunye ne-plutonium (Pu), inokubangela utyhileko olumandla lwangaphakathi xa zingena emzimbeni. I-α -nuclide iyona nuclide ephambili yeemveliso ze-fission kwaye kufuneka ilawulwe ngokungqongqo xa kuthelekiswa ne-cesium (Cs) -137 kunye ne-strontium (Sr) -90. Ubuchule bokususwa ngokufanelekileyo kwee-alpha nuclides kumanzi amileyo kufuneka kuphuhliswe. Ukuza kuthi ga ngoku, amanzi amileyo aqokelelwa kwigumbi lonyaka elingaphantsi kwesakhiwo sereactor seYunithi 2, kwaye intlenga kumanzi amileyo yahlalutywa ngohlalutyo lweradiochemical. Iisampulu eziqulathe amacandelo oludaka oluxutyiweyo olusuka kumanzi amileyo esakhiwo sereactor ziqinisekise ubukho bealpha radionuclides. Ukuze uqhubeke nokunyanga amanzi amileyo nzulu kwizakhiwo zereactor kwixa elizayo, ukuqonda okungcono kweentlobo ezahlukeneyo ze-alpha emitters kuyafuneka, ngakumbi ezo ziqulethe izinto eziqinileyo kumanzi amileyo. Kulo cwaningo, ii-particles ze-radioactive ezihambelana ne-Cs particles (CsMPs) zifunyenwe ngaphandle kwendawo ye-FDiNPS, kwaye ukubunjwa kwazo ngokomzimba kunye neekhemikhali kunye ne-morphology zahlaziywa 3, 4, 5, 6, 7, 8. Abe et al. iqokelele ii-CsMP ezikhutshwe yi-FDiNPS kwi-atmosfera kwaye zihlalutye ngokusebenzisa i-synchronous X-rays ukufumana i-U kwii-CsMPs. Ochiai et al. ifumene amakhulu e-nanometers e-U particles kwi-CsMP ngohlalutyo lwe-SEM-EDX. Ipatheni ye-diffraction ye-UO2 kwi-magnetite yabonwa nge-microscope yokudlulisa i-electron, kwaye iziphumo zibonise ukubunjwa kwe-UO2. Ngokufanayo, iipatheni ze-diffraction ye-UO2 kunye ne-zirconia zifunyenwe kwiinqununu ezixubileyo ze-Zr kunye ne-U kwi-CSMP. Oku kubonisa ukuba i-U ikhona kwi-CsMP ngendlela ye-UO2 kunye ne-U-Zr nanocrystals. UKurihara et al. I-8 ihlalutye i-isotope ratios ye-235U kunye ne-238U kwi-CsMP nge-nanoscale sub-ion mass spectrometry kwaye yafumanisa ukuba kukho i-U ekubunjweni kwamafutha kwi-reactor no. 2 kwi-CsMP. Ucazululo lomhlaba 9, 10, 11, 12, 13, iisuntswana eziphuma emoyeni kunye neeCsMPs7 nazo zinike ingxelo yokukhutshelwa kwamafutha enziwe ngepolyurethanes kokusingqongileyo. UBuddha
