Nuclear fission tsim kom sov
Reactors siv uranium rau nuclear roj. Cov uranium tau ua tiav rau hauv cov me me ceramic pellets thiab muab tso ua ke rau hauv cov hlau kaw uas hu ua roj rods. Lub tshav kub tsim los ntawm fission hloov cov dej mus rau hauv chav, uas tig lub turbine los tsim hluav taws xob tsis muaj carbon.
Tom qab ntawd, ib tug kuj yuav nug, nws yuav siv sij hawm ntev npaum li cas los tsim ib tug nuclear fais fab nroj tsuag?
Niaj hnub nuclear fais fab nroj tsuag tau npaj rau kev tsim kho hauv tsib xyoos lossis tsawg dua (42 lub hlis rau CANDU ACR-1000, 60 lub hlis los ntawm kev txiav txim rau kev ua haujlwm rau AP1000, 48 lub hlis los ntawm thawj qhob rau kev ua haujlwm rau EPR thiab 45 lub hlis rau ESBWR) as opposed to over a kaum xyoo rau qee qhov dhau los nroj tsuag.
Qhov thib ob, lub zog nuclear ua haujlwm li cas ib kauj ruam? Cov txheej txheem nyob rau hauv uas lub zog nuclear yog tsim los ntawm ib tug series ntawm cov kauj ruam:
- Splitting ntawm Atoms. Uranium atoms, nyob rau hauv daim ntawv ntawm ceramic-coated pellets, yog muab tso rau hauv ib tug reactor core.
- Kev nqus. Cov rods tswj tau siv los nqus cov dawb floating neurons tso tawm thaum lub sij hawm fission txheej txheem.
- Kub.
- Dej thiab kav dej.
Tsis tas li ntawd, qhov twg yuav tsum tsim cov chaw tsim hluav taws xob nuclear?
Vim tag nrho nuclear reactors Hauv Tebchaws Meskas xav tau dej los ua haujlwm, koj yuav tsum tsim ib qho ze ntawm lub pas dej lossis tus dej (txawm hais tias nws muaj peev xwm tsim lub pas dej cuav, ib yam li Dominion. Cov tiam North Anna Hwj chim Chaw nres tsheb hauv Central Virginia).
Puas yog nuclear pheej yig dua hnub ci?
Lawv pom thaum ntawd hnub ci tshwm pheej yig dua nuclear , intermittency (lub hnub tsis ci 24 teev ib hnub twg) txhais tau tias hnub ci cov nroj tsuag ua haujlwm ntawm 20 mus rau 30 feem pua ntawm cov peev txheej. Qhov no yog qis dua tshaj qhov nruab nrab 90 feem pua rau a nuclear cog. “Los ntawm qhov ntsuas ntawd, nuclear yog ntau tshaj kev sib tw,” Durning sau.

Vim li cas kuv lub tshuab hluav taws xob tsis tsim hluav taws xob?
Feem ntau ua rau lub tshuab hluav taws xob portable tsis tsim hluav taws xob yog los ntawm kev poob ntawm cov hlau nplaum seem. Generators ua hauj lwm los ntawm kev txav hluav taws xob conductors los ntawm magnetic teb. Koj lub tshuab hluav taws xob tsis muaj hlau nplaum. Thaum cov hlau nplaum seem ploj lawm, lub tshuab hluav taws xob yuav tsis muaj zog thaum pib
Lub teeb ntsuas hluav taws xob siv los kuaj xyuas hluav taws xob li cas?
Lub teeb ntsuas hluav taws xob siv lub teeb tuav hauv ib qho kev sojntsuam txuas nrog tus pas nrig taw tes nrog cov hlau txuas txuas. Qhov kev tsim no yog qhov zoo tshaj plaws rau kev tho cov hlau, kuaj lub fuse lossis kuaj xyuas qhov nqi ntawm lub roj teeb. Yog tias muaj hluav taws xob tam sim no, lub teeb yuav teeb pom tseeb tias lub voj voog muaj zog thiab ua haujlwm zoo
Lub zog hluav taws xob hloov hluav taws xob li cas?
Tab sis yuav ua li cas qhov no ua hauj lwm nyob rau hauv cov nqe lus ntawm circuits? Qhov hluav taws xob muaj peev xwm hloov pauv mus rau lub zog hluav taws xob li niaj zaus thaum cov hluav taws xob txav mus los ntawm lub voj voog. Tom qab ntawd, lub zog hluav taws xob tau xa mus rau cov khoom hauv Circuit Court. Yog hais tias lub voj voog muaj lub teeb, nws tawm los ua lub teeb lub zog thiab lub zog hluav taws xob tsis zoo
Dab tsi yog cov yam ntxwv ua siab hloov hluav taws xob hloov hluav taws xob LET muaj thaum piv nrog LET hluav taws xob tsawg?
Dab tsi yog cov yam ntxwv ua kom muaj hluav taws xob hloov hluav taws xob siab (LET) hluav taws xob muaj thaum piv nrog cov hluav taws xob qis-LET? Cov huab hwm coj ntau ntxiv, txo qhov nkag mus. (Vim lawv cov nqi hluav taws xob thiab cov khoom loj heev, lawv ua rau ntau ionizations hauv cov ntaub so ntswg, sai sai poob lub zog
Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms?
Tus nqi zoo attracts tus nqi tsis zoo thiab ua rau lwm tus nqi zoo. Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms? Cov nqi hluav taws xob yog cov cuab yeej ntawm tag nrho cov atoms
