Izinto ezilinganisiwe zomhlaba ezingavamile

Ama-neutron ku-thermal neutron reactors adinga ukulinganiswa. Ngokuvumelana nesimiso sama-reactors, ukuze kuzuzwe umphumela omuhle wokulinganisa, ama-athomu alula anezinombolo ezinkulu eduze nama-neutron anenzuzo ekulinganiseni kwe-neutron. Ngakho-ke, izinto zokulinganisa zibhekisela kulezo zinto ze-nuclide eziqukethe izinombolo zesisindo esiphansi futhi akulula ukubamba ama-neutron. Lolu hlobo lwento lunengxenye enqamulayo ye-neutron ehlakazekayo enkulu kanye nengxenye encane yokumuncwa kwe-neutron. Ama-nuclide ahlangabezana nalezi zimo ahlanganisa i-hydrogen, i-tritium,i-beryllium, kanye ne-graphite, kuyilapho angempela asetshenziswayo ahlanganisa amanzi asindayo (D2O),i-beryllium(Be), i-graphite (C), i-zirconium hydride, nezinye izinhlanganisela zomhlaba eziyivelakancane.

Izingxenye ezinqamulayo ze-neutron zokubamba zeumhlaba ongavamileizakhii-yttrium,i-cerium, futhii-lanthanumzonke zincane, futhi zakha ama-hydride ahambisanayo ngemva kokumuncwa kwe-hydrogen. Njengabathwali be-hydrogen, angasetshenziswa njengamamodareyitha aqinile kuma-reactor cores ukuze kwehliswe izilinganiso ze-neutron futhi kwandiswe amathuba okusabela kwenyukliya. I-Yttrium hydride iqukethe inani elikhulu lama-athomu e-hydrogen, elilingana nenani lamanzi, futhi ukuzinza kwayo kuhle kakhulu. Kuze kube ngu-1200 ℃, i-yttrium hydride ilahlekelwa yi-hydrogen encane kakhulu, iyenze ibe into ethembisayo yokwehlisa izinga lokushisa kwe-high-temperature.
