Abstract
Reducing separated weapon grade (WG) plutonium is very crucial since this plutonium may be misused and/or released accidentally into the environment. Burning WG plutonium in nuclear reactors can help to solve this serious problem effectively. In this study, the incineration of WG plutonium mixed with thorium in a (DT) fusion driven high power density hybrid reactor was investigated for an operation period of 24 months. Furthermore, the effect of using different coolants on the burning of WG plutonium in the hybrid blanket was examined. Numerical calculations showed that WG plutonium can be denatured to reactor grade level within a very short time by using a high power density hybrid reactor. Moreover, addition of WG plutonium to thorium improved the neutronic performance of the reactor significantly.
Kurzfassung
Die Verringerung von waffenfähigem Plutonium ist sehr wichtig, da dieses Plutonium missbraucht und/oder durch einen Unfall in die Umwelt gelangen werden könnte. Die Verbrennung von waffenfähigem Plutonium in Kernreaktoren kann dieses Problem effektiv lösen helfen. In der vorliegenden Studie wurde die Verbrennung von waffenfähigem Plutonium gemischt mit Thorium in einem (DT) fusionsgetriebenen Hochleistungshybridreaktor untersucht für einem Betriebszeitraum von 24 Monaten. Des Weiteren wurde der Effekt der Verwendung verschiedener Kühlmittel auf die Verbrennung von waffenfähigem Plutonium in der Hybridummantelung untersucht. Numerische Berechnungen zeigen, dass waffenfähiges Plutonium mit Hilfe eines Hybridreaktors in sehr kurzer Zeit denaturiert werden kann auf ein Maß, so dass es für Reaktoren verwendbar ist. Darüber hinaus verbessert der Zusatz von waffenfähigem Plutonium zu Thorium die Neutroneneigenschaften des Reaktors erheblich.
