Zinthu zosawerengeka zapadziko lapansi

Ma nyutroni mu ma nyutroni otenthetsera amafunikira kuwongolera.Malinga ndi mfundo ya ma reactors, kuti akwaniritse zowongolera bwino, maatomu opepuka okhala ndi manambala ambiri pafupi ndi ma neutroni ndi opindulitsa pakuwongolera kwa neutroni.Chifukwa chake, zida zowongolera zimatanthawuza zida za nuclide zomwe zili ndi manambala otsika kwambiri ndipo ndizosavuta kugwira ma neutroni.Zinthu zamtunduwu zimakhala ndi gawo lalikulu lomwazikana ndi neutroni ndi gawo laling'ono la mayamwidwe a neutroni.Ma nuclide omwe amakwaniritsa izi ndi monga hydrogen, tritium,beryllium, ndi graphite, pamene zenizeni zomwe zimagwiritsidwa ntchito zimaphatikizapo madzi olemera (D2O),beryllium(Be), graphite (C), zirconium hydride, ndi zinthu zina zosowa zapadziko lapansi.

The matenthedwe nyutroni kutenga mtanda zigawo zadziko losowazinthuyttrium,cerium,ndilanthanumzonse ndi zazing'ono, ndipo zimapanga ma hydrides ofanana pambuyo pa kuyamwa kwa haidrojeni.Monga zonyamulira ma haidrojeni, atha kugwiritsidwa ntchito ngati owongolera olimba mu ma rector cores kuti achepetse kuchuluka kwa ma neutroni ndikuwonjezera mwayi wanyukiliya.Yttrium hydride ili ndi maatomu ambiri a haidrojeni, ofanana ndi kuchuluka kwa madzi, ndipo kukhazikika kwake ndikwabwino kwambiri.Mpaka 1200 ℃, yttrium hydride imangotaya haidrojeni pang'ono, ndikupangitsa kuti ikhale yodalirika yochepetsera kutentha kwambiri.
