Abstract
Heavy metal molten salts have a good potential to be used in fusion reactors due to their capability of increasing fusion power and producing fissile fuel. In this study, the effect of various molten salts bearing nuclear fuel (99.5 % Flibe + 0.5 % Weapon grade (WG) PuF4, 99 % Flibe + 1 % WG PuF4, 99.5 % Flibe + 0.5 % Reactor Grade (RG) PuF4, 99 % Flibe + 1 % RG PuF4, 75 % LiF + 25 %ThF4, 75 % LiF + 24 % ThF4 + 1 % 233UF4 and 75 % LiF + 23 %ThF4 + 2 % 233UF4) on the neutronic performance of a magnetic fusion reactor called ARIES-RS was investigated. Neutron transport calculations were performed with the help of the code, Scale4.3. Numerical results showed that a significant enhancement on the neutronic performance was achieved with respect to the energy multiplication and fissile fuel breeding by keeping the sufficient tritium for the (DT) driver compared to the pure ARIES-RS fusion reactor for all investigated coolants except for the salts of 75 % LiF + 25 % ThF4 and 75 % LiF + 24 % ThF4 + 1 % 233UF4. Since these two salts did not satisfy tritium self-sufficiency.
Kurzfassung
Geschmolzene Schwermetallsalze haben wegen ihrer Fähigkeit die Fusionsenergie zu erhöhen und spaltbaren Brennstoff zu erzeugen gute Vorraussetzungen bei Fusionsreaktoren zum Einsatz zu kommen. In der vorliegenden Arbeit wird der Einfluss verschiedener Brennstoff-haltiger geschmolzener Salze (99,5 % Flibe + 0,5 % Weapon grade (WG) PuF4, 99 % Flibe + 1 % WG PuF4, 99,.5 % Flibe + 0,5 % Reactor Grade (RG) PuF4, 99 % Flibe + 1 % RG PuF4, 75 % LiF + 25 % ThF4, 75 % LiF + 24 % ThF4 + 1 % 233UF4 and 75 % LiF + 23 % ThF4 + 2 % 233UF4) auf das neutronenphysikalische Verhalten eines magnetischen Fusionsreaktors, ARIES-RS, untersucht. Neutronentransportrechnungen wurden durchgeführt mit Hilfe des Codes Scale4.3. Die numerischen Ergebnisse zeigen, dass eine signifikante Erhöhung des neutronenphysikalische Verhaltens in Bezug auf die Energiemultiplikation und die Erzeugung spaltbaren Brennstoffs erreicht wird durch Aufbewahrung von ausreichend Tritium für die (DT) Treiber verglichen mit dem reinen ARIES-RS Fusionsreaktor für alle untersuchten Kühlmittel, außer für die Salze von 75 % LiF + 25 % ThF4 und 75 % LiF + 24 % ThF4 + 1 % 233UF4. Diese beiden Salze erfüllen nicht die Selbstversorgung mit Tritium.
