Uranium-235 fissions nrog qis-zog thermal neutronsvim tias lub zog sib txuas los ntawm kev nqus ntawm neutron ntau dua li lub zog tseem ceeb uas xav tau rau fission; Yog li ntawd uranium-235 yog cov khoom siv fissile.
Dab tsi ua rau cov khoom fissionable?
A nuclide uas muaj peev xwm ua rau muaj kev sib cais tom qab ntes cov hluav taws xob siab (ceev) neutrons lossis qis zog thermal (slow) neutrons Txawm hais tias yav tas los siv los ua ib lo lus rau fissile cov ntaub ntawv, cov ntaub ntawv fissionable kuj suav nrog cov (xws li uranium-238) uas tuaj yeem raug fissionedonly nrog high-zog neutrons.
Uranium ua cov xov tooj cua ua li cas?
Uranium tsis muaj zog hauv xov tooj cua vim tias tag nrho cov isotopes ntawm uranium tsis ruaj khov; lub neej ib nrab ntawm nws cov isotopes tshwm sim nyob nruab nrab ntawm 159, 200 xyoo thiab 4.5 billion xyoo. … Uranium decays maj mam los ntawm emitting ib tug alpha particle.
Vim li cas uranium-238 tsis tuaj yeem fissionable?
U- 238 yog fissionable isotope, txhais tau hais tias nws tuaj yeem nkag mus rau nuclear fission, tab sis cov neutrons raug rho tawm ntawm nws yuav xav tau ntau lub zog thiaj li ua rau fission tshwm sim. … vim ntau lub zog xav tau, U- 238 ib txwm yuav tsis raug fission hauv lub tshuab hluav taws xob nuclear.
Dab tsi ua rau uranium fission?
Ib lub atom muaj ib lub nucleus (los yog core) uas muaj protons thiab neutrons, uas yog ib puag ncig los ntawm electrons. … Thaum lub sij hawm nuclear fission, ib lub neutron collides nrog ib tug uranium atom thiab splits nws, tso ib tug loj npaum li cas ntawm lub zog nyob rau hauv daim ntawv ntawm tshav kub thiab hluav taws xob. Ntau cov neutrons kuj raug tso tawm thaum lub uranium atom splits.
