$ThC_2$ yakıtlı ve $Li_{17}Pb_{83}$ soğutuculu bir füzyon-fisyon reaktöründe trityum üretim bölgesinde farklı Li bileşikleri kullanılmasının reaktör performansına etkilerinin değerlendirilmesi

Bu çalışmada $ThC_2$ yakıtlı ve $Li_{17}Pb_{83}$ soğutuculu bir füzyon-fisyon reaktörü ele alınmıştır. Reaktörün trityum üretim bölgesinde LiH ve $LiO_2$ olmak üzere iki farklı Li bileşiği kullanılmıştır. Reaktörde füzyon nötron kaynağı olarak 14.1 MeV D-T nötronları kullanılmış ve $\Delta t=3$ gün olmak üzere 2 yıllık çalışma süresince reaktörün nötronik performansı, termal nötronlarla fisyon olabilen yakıt ve nükleer güç üretiminin değişimleri incelenmiştir. İlk duvar füzyon nötron akısı 5 $MW/m^2$ olan mantoda o yakıt bölgesinde $\frac{V_m}{V_f}$=2 hacimsel oranı alınmıştır. Trityum üretim bölgesinde LiH kullanılması 2 yıllık reaktör işlem zamanı için en yüksek trityum üretimini sağlamıştır. Fisyon olabilen kaliteli yakıt üretiminde en yüksek değere mantonun trityum üretim bölgesinde $LiO_2$ kullanılmasıyla ulaşılmıştır.

Investigation of the effects of reactor performance of using different Li compounds in tritium breeding zones of a fusion-fission reactor fuelling with Uc2 and cooling with $Li_{17}Pb_{83}$

In this work, a fusion-fission reactor fuelling with $ThC_2$ and cooling with $Li_{17}Pb_{83}$ are investigated. Two different Li compounds as LiH and $LiO_2$ are used in tritium breeding zones of the reactor. 14.1 MeV D-T neutrons are used as a fusion neutron source and it is investigated that variations of neutronic performances, fissile fuel breeding and fission power production as $\Delta t=3$ days during a reactor operation period over two years. In the blanket in which first-wall neutron flux is 5 $MW/m^2$ and volumetric ratio is selected as $\frac{V_m}{V_f}$=2 in the fuel zone. During a reactor operation period over two years, using LiH in tritium breeding zones of the reactor provides highest tritium breeding rate. Highest value of fissile fuel breeding is reached with using of $LiO_2$ in tritium breeding zones of the reactor.
