Neutrons nyob rau hauv Thermal Neutron Reactors yuav tsum tau ua kom tsawg. Raws li cov ntsiab cai ntawm reactors, txhawm rau kom ua tiav cov txiaj ntsig kev ua tiav zoo, lub teeb atomer nrog cov lej loj nrog cov neeg neutron sim. Yog li, cov khoom siv nruab nrab hais txog cov khoom nuclide uas muaj cov lej tsawg thiab tsis yooj yim los ntes neutrons. Cov khoom siv no muaj qhov loj dua Neutron scativing cross-section-seem thiab ib qho me me nruab nrab kev tso cai hla-ntu. Lub nuclides uas tau raws li cov mob no suav nrog cov tshuaj hydrogen, tritium,beryllium, thiab graphite, thaum lub sij hawm tiag tiag uas siv suav nrog cov dej hnyav (D2O),beryllium(Yog), graphite (c), zirconium hydride, thiab qee cov hauv ntiaj teb tsawg kawg.
Lub thermal Neutron ntes hla ntu ntawmTsis tshua muaj ntiaj tebNtsiab lusyttrium,xiIAB, thiablus qhiaYog txhua tus me, thiab lawv tsim cov dej kas cees tom qab nqus dej. Raws li cov nqa khoom ntau hydrogen, lawv tuaj yeem siv ua cov tuberator khov hauv cov tshuaj tua neeg kom qeeb nucderron cov nqi thiab nce qhov tshwm sim ntawm nuclear cov kev tshua. Yttrium hydride muaj ntau ntawm hydrogen abs, sib npaug nrog cov dej, thiab nws cov ruaj khov yog qhov zoo heev. Txog 1200 ℃, yttrium hydride tsuas yog poob ntau heev me ntsis hydrogen, ua rau nws muaj kev pab cuam kub reactor frequelation cov khoom.
