Thaum ib lub tshuab hluav taws xob siv hluav taws xob siv tau tsuas yog siv tau yooj yim tab sis tsis tshua muaj isotope uranium-235 rau roj, ib lub tshuab reactor ua haujlwmuranium-238 lossis thorium, ntawm qhov loj. Muaj ntau ntau.

Cov khoom siv fissionable twg yog siv rau hauv cov reactor breeder?

Thermal breeder reactor uas siv thermal-spectrum (ie: moderated) neutrons los yug fissile uranium-233 los ntawm thorium (thorium roj voj voog). Vim yog tus cwj pwm ntawm ntau yam nuclear fuels, lub thermal breeder xav tias kev lag luam ua tau tsuas yog nrog cov roj thorium, uas zam kev tsim ntawm cov transuranics hnyav dua.

Dab tsi yog ob yam fissionable uas nquag siv hauv nuclear reactors?

Ntxiv cov neutrons kuj tau tso tawm uas tuaj yeem pib cov tshuaj tiv thaiv kab mob. Thaum txhua lub atom sib cais, lub zog loj heev raug tso tawm. Uranium thiab plutonium feem ntau yog siv rau fission tshwm sim hauv nuclear fais fab reactors vim lawv yooj yim los pib thiab tswj.

Lub ntsiab lus dab tsi uas feem ntau siv hauv nuclear reactors?

Cov roj uas nuclear reactors siv los tsim nuclear fission yog pellets ntawm element uranium. Hauv lub reactor nuclear, atoms ntawm uranium raug yuam kom tawg. Raws li lawv sib cais, cov atoms tso cov khoom me me hu ua fission khoom. Fission cov khoom ua rau lwm cov uranium atoms sib cais, pib achain reaction.

Yuav ua li cas cov roj nuclear tshiab tsim nyob rau hauv lub reactor breeder?

Cov neeg yug tsiaj sai sai siv cov neutrons ceev kom txhawb nqa cov tshuaj tiv thaiv fission nrog rau kev yug me nyuam. Cov isotopes uas tsis yog fissile 238 U thiab 232 Th hloov mus rau fissile isotopes ntawm 239 Pu thiab 233U, feem, yog li tsim cov roj tshiab thaum lub sijhawm ua haujlwm reactor.

Qhov twg sidehows pib?

Sideshows thawj zaug tshwm sim ntawm txoj kev ntawm Oakland, California thaum lub sijhawm nruab nrab xyoo 1970 Thawj qhov kev ua yeeb yam yog thawj zaug ad hoc carhows uas tib neeg yuav tuaj koom hauv Eastmont Mall lossis Foothill Square chaw nres tsheb.

Hom kev sib txuas lus twg yog qhov siab tshaj hauv kev tshaj tawm kev nplua nuj?

Kev sib txuas lus ntsej muag yog qhov nruab nrab nplua nuj tshaj plaws raws li MRT vim nws tso cai rau kev sib pauv ntawm tus kheej ib txhij los ntawm cov ntsiab lus lus, lub suab, lub ntsej muag, kev taw qhia ntawm saib, gestures, thiab postures.
