Iineutron kwi-thermal neutron reactors kufuneka zimodareyithwe.Ngokomgaqo we-reactors, ukuze kuphunyezwe isiphumo esihle sokumodareyitha, iiathom ezikhanyayo ezinamanani obunzima kufutshane ne-neutron ziluncedo kwimodareyitha ye-neutron.Ngoko ke, izinto zokumodareyitha zibhekisela kwezo zinto ze-nuclide eziqulethe amanani aphantsi obunzima kwaye akukho lula ukubamba i-neutron.Olu hlobo lwemathiriyeli ine-neutron enkulu esasaza icandelo elinqamlezayo kunye necandelo elincinci le-neutron lokufunxa.Iinuclides ezihlangabezana nale meko ziquka i-hydrogen, i-tritium,ibheriliya, kunye negraphite, ngelixa ezona zisetyenziswayo ziquka amanzi anzima (D2O),ibheriliya(Be), igraphite (C), i-zirconium hydride, kunye nezinye iikhompawundi zomhlaba ezinqabileyo.
Neutron thermal bamba amacandelo cross ofumhlaba onqabileyoizintoiyttrium,i-cerium, kwayelanthanumzonke zincinci, kwaye zenza iihydrides ezihambelanayo emva kokufunxwa kwehydrogen.Njengabathwali be-hydrogen, zinokusetyenziswa njengeemodareyitha eziqinileyo kwii-reactor cores ukucothisa amaxabiso e-neutron kunye nokwandisa ukuba nokwenzeka kokusabela kwenyukliya.I-Yttrium hydride iqulethe inani elikhulu le-athomu ye-hydrogen, elilingana nomlinganiselo wamanzi, kwaye ukuzinza kwayo kugqwesileyo.Kude kube yi-1200 ℃, i-yttrium hydride ilahlekelwa yi-hydrogen encinci kuphela, iyenze ibe sisixhobo esithembisayo sobushushu obuphezulu bereactor.
