Txawm hais tias lub zog tsim los ntawm fission yog piv rau yam uas tsim los ntawm kev fusion , lub hauv paus ntawm lub hnub yog dominated los ntawm hydrogen thiab ntawm qhov kub thiab txias qhov twg hydrogen kev fusion yog ua tau, thiaj li hais tias qhov tseem ceeb ntawm lub zog ib cubic meter yog nyob rau hauv kev fusion es ces tus fission ntawm cov xov tooj cua isotopes tsawg heev.

Hauv qhov no, puas yog lub hnub nuclear fusion lossis fission?

Cov Hnub yog lub hnub qub tseem ceeb, thiab yog li tsim nws lub zog los ntawm nuclear fusion ntawm hydrogen nuclei rau hauv helium. Hauv nws qhov tseem ceeb, lub Hnub fuses 500 lab metric tons ntawm hydrogen txhua ob.

Tsis tas li ntawd, lub hnub puas raug fission? Fission yog kev sib cais ntawm cov atoms, xws li los ntawm radioactive decay los yog los ntawm kev sib tsoo. Muaj tseeb tias radioactive decay tshwm sim vim qhov hnub Muaj ntau lub xov tooj cua isotopes xws li thorium, uranium thiab lwm yam. Nws tau hais tias nuclear fusion tso tawm lub zog uas yog 1000 npaug ntau dua li ntawm nuclear. fission.

Ib yam li ib tug yuav nug, puas yog fission lossis fusion muaj zog dua?

Fission tsuas yog tsim ntau lub zog tshaj nws siv nyob rau hauv loj nuclei (cov piv txwv feem ntau yog Uranium & Plutonium, uas muaj nyob ib ncig ntawm 240 nucleons (nucleon = proton los yog neutron)). fusion tsuas yog tsim ntau lub zog tshaj nws siv hauv cov nuclei me me (hauv cov hnub qub, Hydrogen & nws cov isotopes fusing rau hauv Helium).

Lub hnub puas yog nuclear reactor?

Cov hnub yog qhov zoo tshaj plaws nuclear kev fusion reactor ib ncig. NASA Goddard Spaceflight Center Yooj yim yooj yim: Lub ntiajteb txawj nqus. Fusion hauv lub hnub chaw ua haujlwm los ntawm nias plaub lub atoms hydrogen ua ke los tsim ib lub helium atom thiab lub zog. Qhov hnyav hnyav ntawm lub hnub muab lub siab xav tau.
