$UC_2$ yakıtlı bir hibrid reaktörün farklı nötron kütüphanelerine göre nötronik performanslarının karşılaştırılması

Bu çalışmada 14.1 MeV D-T füzyon nötron kaynaklı bir hibrid mantonun $\Delta$t=10 gün olmak üzere 4 yıllık reaktör çalışma süresince nötronik performansının, termal nötronlarla parçalanabilen yakıt ve nükleer ısı üretiminin farklı nötron kütüphanelerine göre değişimleri incelenmiştir. İlk duvar füzyon nötron akısı 5 MW/$m^2$ olan mantoda nükleer yakıt olarak $UC_2$ ve soğutucu olarak tabii lityum kullanılmış, yakıt bölgesinde $\frac{V_m}{V_f}$ =2 hacimsel oranı alınmıştır. Ayrıca, nötron reaksiyonları için nötron enerji grup yapılarının ve enerji dağılım aralıklarının manto performansı üzerindeki etkilerinin önemi ortaya koymuştur.

Comparison of neutronic performances according to different neutron libraries hybrid reactor fuelling with $UC_2$

In this work, a neutronic performance, fissile fuel breeding and nuclear heat production were investigated in a hybrid blanket with 14.1 MeV D-T fusion neutron sources $\Delta$t=10 days during a plant operation over four years. In the blanket in which first-wall neutron flux is 5 MW/$m^2$, $UC_2$ is used as a nuclear fuel and natural lithium is used as a moderator. A volumetric ratio is selected as $\frac{V_m}{V_f}$ =2 in the fuel zone. Furthermore, it is pointed out that neutron energy group configurations and energy distribution intervals affect blanket performance.
