Doğal Li soğutuculu-$ThSi_2$ yakıtlı bir füzyon-fisyon hibrid reaktöründe farklı trityum üretim malzemelerinin etkinliğinin incelenmesi

Bu çalışmada $ThSi_2$ yakıtlı bir füzyon-fisyon hibrid reaktör ele alınmıştır. Reaktörde soğutucu olarak doğal Li seçilmiş ve trityum üretim bölgesinde $Li_2Ti0_3$, $Li_2Zr0_3$, $Li_4Si0_4$ ve $Li_2O$ gibi dört farklı Li bileşikleri kullanılmıştır. Reaktörde füzyon nötron kaynağı olarak 14.1 MeV D-T nötronları kullanılmış ve $Delta t=10$ gün olmak üzere 4 yıllık çalışma süresince reaktörde trityum üretimi, $^{233}U$ izotopu üretimi, fisyon enerjisi üretimi ve nükleer güç üretiminin değişimleri incelenmiştir. 4 yıllık reaktör işlem zamanında trityum üretiminde $Li_2O$, $^{233}U$ izotopu üretiminde ve fisyon enerjisi üretiminde $Li_2Zr0_3$ bileşiğinin kullanıldığı mantolar en iyi sonuçları vermiştir.

Investigation of effectiveness of different tritium breeding materials in a fusion-fission hybrid reactor fuelled with $ThSi_2$-moderated with natural Li

In this work, a fusion-fission reactor fuelling with $ThSi_2$ is investigated. Natural Li is selected as a moderator in the reactor and $Li_2Ti0_3$, $Li_2Zr0_3$, $Li_4Si0_4$ ve $Li_2O$ are used in the tritium breeding zones of the reactor. 14.1 MeV D-T neutrons are used as a fusion neutron source. Tritium breeding rates, $^{233}U$ breeding rates, fission energy breeding rates and fission power production are investigated for At=10 days during a reactor operation period over four years, Using $Li_2O$ in tritium breeding zones of the reactor provided highest tritium breeding rate. Highest value of $^{233}U$ breeding and production of the fission energy are reached with using of $Li_2Zr0_3$ in tritium breeding zones of the blanket.
