Taw qhia rau uranium nuclear fission
Cov tub ntxhais uranium yog ib lub cev nqaij daim tawv. Cov uranium muaj peb isotopes. Lub npe hu ua isotope hais txog tib lub protons hauv lawv lub nucleus, tab sis cov khoom sib txawv uas muaj cov lej sib txawv ntawm neutrons tau muab tso rau hauv tib txoj haujlwm hauv lub sijhawm. , ntawd yog uranium-234, uranium-235 thiab uranium-238. Ntawm lawv, uranium-234 thiab uranium-238 tsis yauv mus rau nuclear fission, thiab tsuas yog uranium-235 isotope atom tuaj yeem hla nuclear fission, lossis uranium-235 yog qhov tseeb hluav taws xob nuclear. Txawm li cas los xij, uranium-235 cov ntsiab lus tawm ntawm kuv yog qhov tsawg heev, uas suav nrog tsuas yog 0.66%, feem coob yog uranium-238, uas suav 99,2%.
