Qhov sib txawv tseem ceeb ntawm fissile thiab fertile isotopes yog tias fissile isotopes yog cov khoom uas tuaj yeem ua rau cov tshuaj tiv thaiv fission, whereas fertile isotope yog cov khoom uas tuaj yeem hloov mus rau hauv fissile isotope.
Cov ntsiab lus fissile isotope thiab fertile isotope tuaj nyob rau hauv qeb ntawm nuclear chemistry. lawv txhais ob hom atoms uas muaj cov lej sib txawv ntawm cov neutrons nrog tib tus lej ntawm cov protons hauv lawv cov nuclei (isotopes) uas yog cov xov tooj cua. Muaj ob hom kev tawm tsam nuclear loj xws li cov tshuaj tiv thaiv fission thiab fusion tshuaj tiv thaiv. Cov fissile isotope thiab fertile isotope muaj txiaj ntsig zoo txog kev cuam tshuam fission.
Fissile Isotopes yog dab tsi?
Fissile isotopes yog atoms uas tuaj yeem ua rau muaj kev cuam tshuam. Cov no kuj muaj npe raws li cov khoom siv fissionable. Qee cov ntaub ntawv fissile paub zoo xws li Uranium-235, Plutonium-239, thiab Uranium-233. Txawm li cas los xij, ntawm peb hom no, tsuas yog Uranium-235 tshwm sim ib txwm muaj thaum lwm ob yog cov tshuaj hluavtaws tsim los ntawm Uranium-238 thiab Thorium-232, raws li.
Daim duab 01: Plutonium Isotope
U-235 yog ib qho isotope ntawm cov tshuaj Uranium, uas yog tsim los ntawm 92 protons thiab 143 neutrons hauv nws cov nucleus. Lub cim tshuaj rau Uranium yog muab raws li 235 92 U. Lub ntuj abundance ntawm U-235 yog hais txog 0.72%. Qhov loj ntawm no isotope yog hais txog 235.043 amu.
Plutonium yog ib qho khoom siv tshuaj lom neeg uas muaj tus lej atomic 94 thiab cim Pu. Nyob rau hauv lub sij hawm ntawm lub ntsiab lus, Plutonium tuaj yeem pom nyob rau hauv cov actinide series ntawm f block ntsiab. Nyob rau hauv chav tsev kub thiab siab, nws yog nyob rau hauv lub solid-state. Lub teeb tsa hluav taws xob ntawm lub caij no tuaj yeem muab tau raws li [Rn]5f67s2 Yog li ntawd, nws muaj rau electrons nyob rau hauv f orbital.
Fertile Isotopes yog dab tsi?
Fertile isotopes yog atoms uas tuaj yeem hloov mus rau fissile isotopes. Cov isotopes fertile no tsis tuaj yeem raug fission lawv tus kheej vim lawv muaj cov neutrons uas tsis muaj zog. Lawv tuaj yeem raug fission tsuas yog hloov lawv tus kheej mus rau fissile isotopes. Qee qhov piv txwv ntawm ib txwm muaj cov isotopes fertile muaj xws li Thorium-232 thiab Uranium-238. Ob qho no tsuas yog ib qho tshwm sim fertile isotopes.
Daim duab 02: Kev hloov pauv ntawm Fertile Isotopes rau Fissile Isotopes
Kev hloov pauv ntawm cov isotopes fertile rau hauv fissile isotopes yog ua los ntawm irradiation ntawm isotopes hauv nuclear reactors. Ntawm no, cov neutrons ua ke nrog cov isotopes ua rau lawv fissile. Tom qab qhov kev hloov dua siab tshiab no, cov khoom siv fissile tshiab tuaj yeem cuam tshuam cov hluav taws xob tawg. Thaum Thorium-232 thiab Uranium-238 hloov mus rau fissile isotopes, cov isotopes no ua Plutonium-239 thiab Uranium-233, raws li.
Qhov txawv ntawm Fissile thiab Fertile Isotopes yog dab tsi?
Qhov sib txawv tseem ceeb ntawm fissile thiab fertile isotopes yog tias fissile isotopes yog cov khoom uas tuaj yeem ua rau cov tshuaj tiv thaiv fission, hos cov isotope fertile yog cov khoom uas tuaj yeem hloov mus rau fissile isotope. Tsis tas li ntawd, fissile isotopes tuaj yeem raug fission tshua ncaj qha, thaum cov isotopes fertile tsis tuaj yeem raug fission ncaj qha. Uranium-235, Plutonium-239, thiab Uranium-233 yog cov piv txwv ntawm fissile isotopes thaum Thorium-232 thiab Uranium-238 yog cov piv txwv ntawm fertile isotopes.
Cov lus hauv qab no qhia txog qhov sib txawv ntawm fissile thiab fertile isotopes.
Summary – Fissile vs Fertile Isotopes
Cov ntsiab lus fissile isotope thiab fertile isotope yog siv feem ntau hauv nuclear chemistry. Qhov sib txawv tseem ceeb ntawm fissile thiab fertile isotopes yog tias fissile isotopes yog cov khoom uas tuaj yeem ua rau cov tshuaj tiv thaiv fission, whereas fertile isotope yog cov khoom uas tuaj yeem hloov mus rau hauv fissile isotope.
