Radioactive (los yog nuclear ) pov tseg yog ib tug byproduct los ntawm nuclear reactors, roj ua cov nroj tsuag, tsev kho mob thiab chaw tshawb fawb. Xov tooj cua pov tseg kuj yog tsim thaum decommissioning thiab dismantling nuclear reactors thiab lwm yam nuclear chaw.
Tseem yuav paub yog, dab tsi yog nuclear pov tseg ua los ntawm?
HLW suav txog ntau dua 95 feem pua ntawm tag nrho cov xov tooj cua tsim tawm hauv cov txheej txheem ntawm nuclear tsim hluav taws xob. Cov xov tooj cua pov tseg los ntawm siv roj pas nrig muaj feem ntau ntawm cesium-137 thiab strontium-90, tab sis nws kuj tseem muaj xws li plutonium, uas tuaj yeem suav hais tias yog transuranic. pov tseg.
Ib yam li ntawd, nuclear pov tseg mus qhov twg? Kev lag luam hluav taws xob tsim tawm feem ntau ntawm nuclear pov tseg nyob rau hauv Teb Chaws Asmeskas, uas tseem khaws cia saum av ze ntawm txhua qhov ntawm 99 kev lag luam nuclear reactors tau tawg nyob ib ncig ntawm lub teb chaws. Nuclear pov tseg khaws cia rau hauv cov pas dej kom txias tau ntau xyoo, thiab qee qhov tau txav mus rau saum av pob zeb pob zeb.
Ib yam li ntawd ib tug yuav nug, yuav ua li cas yog nuclear pov tseg tsim?
Qib siab pov tseg HLW tshwm sim los ntawm 'hluav taws' ntawm uranium roj hauv a nuclear reactor. HLW muaj cov khoom fission thiab cov ntsiab lus transuranic tsim nyob rau hauv lub reactor core. HLW suav tsuas yog 3% ntawm qhov ntim, tab sis 95% ntawm tag nrho cov xov tooj cua ntawm ua pov tseg.
Vim li cas nuclear pov tseg yog teeb meem?
Nuclear khib nyiab . Qhov kev sib tw ntawm kev ua nuclear fais fab kev nyab xeeb tsis tas tom qab lub hwj chim tau tsim. Nuclear roj tseem muaj kev phom sij txaus ntshai rau ntau txhiab xyoo tom qab nws tsis muaj txiaj ntsig hauv kev lag luam reactor. Qhov tshwm sim pov tseg pov tseg teeb meem tau dhau los ua qhov nyuaj rau cov neeg tsim cai.

Dab tsi yog cov khoom pov tseg ntawm cov tshuaj tiv thaiv lub teeb?
Dej, thaum tawg, ua rau oxygen, hydrogen, thiab electrons. Cov electrons txav los ntawm cov qauv hauv chloroplasts thiab los ntawm chemiosmosis, ua ATP. Cov hydrogen hloov mus rau NADPH uas yog tom qab ntawd siv rau hauv cov tshuaj tiv thaiv lub teeb. Oxygen diffuses tawm ntawm cov nroj tsuag raws li cov khoom pov tseg ntawm photosynthesis
Yuav ua li cas koj pov tseg ntawm txoj kev tsheb ciav hlau?
Pov tseg txoj kev tsheb ciav hlau sib txuas hauv qhov chaw pov tseg. Ntau lub xeev muaj cov cai rau hom kev pov tseg uas yuav lees txais kev sib tw tsheb ciav hlau. Hu rau qhov chaw pov tseg kom paub tseeb tias nws puas lees txais cov kev sib raug zoo. Feem ntau, qhov kev txiav txim siab no yog txiav txim los ntawm lub chaw tswj xyuas cov khib nyiab hauv zos lossis hauv koj lub xeev
Puas yog cov tshuaj lom neeg pov tseg puas tsuaj?
Ib yam li cov roj teeb, cov tshuaj spa thiab pas dej ua ke yog cov khib nyiab uas yuav tsum tau muab pov tseg kom zoo - thiab tsis txhob nyob hauv cov thoob khib nyiab
Vim li cas nws nyuaj rau pov tseg cov pov tseg nuclear?
Nuclear pov tseg yog ib qho nyuaj tshaj plaws ntawm cov pov tseg rau kev tswj hwm vim tias nws muaj kev phom sij heev. Vim nws cov xov tooj cua thiab cov khoom muaj kev phom sij heev, cov khib nyiab nuclear yuav tsum tau ua tib zoo khaws cia lossis rov ua dua
Dab tsi yog cov khoom pov tseg ntawm cov saw hlau thauj khoom?
Yog tias muaj cov pa oxygen, kev ua pa ntawm tes hloov lub zog los ntawm ib qho molecule ntawm qabzib mus rau 38 molecules ntawm ATP, tso carbon dioxide thiab dej pov tseg
