Abstract
In this study, salt-heavy metal mixtures consisting of 93–85% Li20Sn80 + 5% SFG-PuO2 and 2–10% UO2, 93–85% Li20Sn80 + 5% SFG-PuO2 and 2–10% NpO2, and 93–85% Li20Sn80 + 5% SFG-PuO2 and 2–10% UCO were used as fluids. The fluids were used in the liquid first wall, blanket, and shield zones of a fusion–fission hybrid reactor system. A beryllium (Be) zone with a width of 3 cm was used for neutron multiplicity between the liquid first wall and the blanket. 9Cr2WVTa ferritic steel with the width of 4 cm was used as the structural material. The contributions of each isotope in the fluids to the nuclear parameters, such as tritium breeding ratio (TBR), energy multiplication factor (M), and heat deposition rate, of the fusion–fission hybrid reactor were calculated in the liquid first wall, blanket, and shield zones. Three-dimensional analyses were performed using the Monte Carlo code MCNPX-2.7.0 and nuclear data library ENDF/B-VII.0.
Kurzfassung
In dieser Studie wurden als Liquide Salz-Schwermetallhaltige Lösungen mit 93–85% Li20Sn80 + 5% SFG-PuO2 und 2–10% UO2, 93–85% Li20Sn80 + 5% SFG-PuO2 und 2–10% NpO2, und 93–85% Li20Sn80 + 5% SFG-PuO2 und 2–10% UCO verwendet. Die Liquiden wurden an der ersten Flüssigwand, am Blanket- und Shield-Bereich des hybriden Reaktorsystems eingesetzt. Für die Neutronenanreicherung wurde zwischen der ersten Flüssigwand und dem Blanket ein drei Zentimeter dicker Beryllium-Bereich (Be) angebracht. Als Baumaterial wurde vier Zentimeter dicker 9Cr2WVTa ferritischer Stahl verwendet. In dieser Studie wurde der Einfluss eines jeden Isotops auf nukleare Parameter wie dem Tritium-Erzeugungssatz (TBR) an der ersten Flüssigwand, am Blanket- und Shield-Bereich des Fusion-Fision-Hybridreaktors, dem Energie-Vervielfältigungsfaktor (M) und dem Anteil der gespeicherten Wärme berechnet.
