Nuclear reactors yog lub plawv ntawm nuclear fais fab nroj tsuag. Lawv muaj thiab tswj cov saw hlau nuclear uas tsim cov cua sov los ntawm txheej txheem lub cevhu ua fission. Cov cua sov ntawd yog siv los ua cov nkev uas tig lub cav los tsim hluav taws xob.
Puas yog nuclear reactors fission lossis fusion?
Thaum fission yog siv nyob rau hauv nuclear fais fab reactors txij li thaum nws tuaj yeem tswj tau, fusion tseem tsis tau siv los tsim lub zog. Qee cov kws tshawb fawb ntseeg tias muaj cib fim ua li ntawd. Fusion muab lub sijhawm txaus siab, txij li fusion tsim cov khoom siv hluav taws xob tsawg dua li fission thiab muaj ze li ntawm cov roj tsis txwv.
Fission tshwm sim hauv nuclear reactor li cas?
Lub sijhawm nuclear fission, ib lub neutron tsoo nrog uranium atom thiab tawg nws, tso tawm ntau 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 sib cais. Cov neutrons txuas ntxiv sib tsoo nrog lwm cov uranium atoms, thiab cov txheej txheem rov ua nws tus kheej ntau dua.
Puas yog fission reactor ua tau?
Muaj ntau lub nuclear fission reactors uas tau muab lub zog muaj txiaj ntsig. Txog tam sim no, muaj pes tsawg qhov siv tau fusion reactors. Nws hloov tawm tias nuclear fission tsis yog qhov nyuaj dhau. Yog hais tias koj noj ib co uranium-235 thiab tua ib tug neutron ntawm nws, lub uranium absorbs lub neutron thiab ua uranium-236.
Puas yog fission chemical lossis nuclear?
Nuclear fission tshwm sim nrog cov ntsiab lus hnyav, qhov twg cov hluav taws xob hluav taws xob thawb lub nucleus sib nrug dominates lub zog nuclear zog tuav nws ua ke. Txhawm rau pib cov kev cuam tshuam fission feem ntau, lub atom yog bombarded los ntawm ib tug neutron los tsim ib tug tsis ruaj tsis khov isotope, uas undergoes fission.

Puas yog nplawm lub tank reactor?
Lub nruam stirred-tank reactor, tseem hu ua vat- los yog backmix reactor, mixed flow reactor, los yog ib tug nruam-flow stirred-tank reactor, yog ib tug qauv qauv rau ib tug tshuaj reactor nyob rau hauv chemical engineering thiab ib puag ncig engineering.
Puas yog kev sim nuclear puas ua rau huab cua puas tsuaj?
Txawm li cas los xij, ntau qhov kev sim riam phom nuclear tau ua nyob rau hauv huab cua thiab hauv av thaum lub sijhawm 1945– 2013 (kev sim nuclear kawg tau ua los ntawm North Kauslim) yog lub luag haujlwm rau Tam sim no ib puag ncig kev sib kis nrog cov pov tseg hluav taws xob uas ua rau thaj chaw ecologically thiab kev sib raug zoo, vim yog… Puas yog foob pob nuclear rhuav tshem huab cua?
Qhov txawv ntawm fission thiab fusion yog dab tsi?
Fission yog qhov sib cais ntawm qhov hnyav, tsis ruaj khov rau hauv ob lub zog sib zog, thiab fusion yog txheej txheem uas ob lub teeb nuclei ua ke ua ke tso tawm ntau lub zog. Txawm li cas los xij, ob qhov txheej txheem muaj lub luag haujlwm tseem ceeb hauv yav dhau los, tam sim no thiab yav tom ntej ntawm kev tsim hluav taws xob.
Fission puas tsim tau lub zog?
Fission thiab fusion yog ob lub cev txheej txheem uas tsim ntau lub zog los ntawm atoms. Lawv muab ntau lab lub zog ntau dua li lwm qhov los ntawm kev tawm tsam nuclear. Puas yog lub zog tsim los ntawm fusion? Nuclear Fusion cov tshuaj tiv thaiv lub hnub thiab lwm lub hnub qub.
Lub sijhawm nuclear fission zog raug tso tawm los ntawm?
Nuclear fission hauv fissile fissile Fissile vs fissionable Ib tug nuclide muaj peev xwm ntawm kev fission (txawm tias tsis tshua muaj tshwm sim) tom qab ntes cov neutron ntawm siab lossis qis zog yog hu ua "fissionable". Lub fissionable nuclide uas tuaj yeem cuam tshuam rau fission nrog qis-zog thermal neutrons nrog qhov ua tau zoo yog hu ua "
