Abstract

Problems related to use of Erbium as burnable poison for VVER are discussed. Comparison is made between neutronics characteristics of Uranium-Gadolinium and Uranium-Erbium fuel cycles. The study shows that use of Erbium as burnable poison allows decreasing the peaking factor in the core. Meanwhile residual Erbium at the end of the fuel cycle makes it necessary to increase fuel enrichment. There is made the conclusion of prospects of using Erbium as burnable poison for VVER.

Kurzfassung

Vor- und Nachteile des Einsatzes von Erbium als Reaktorgift in WWER Reaktoren werden vorgestellt. Dazu werden die Neutronenparameter der Brennstoffzyklen beim Einsatz von Uran-Gadolinium und von Uran-Erbium verglichen. Die Untersuchung zeigt, dass der Einsatz von Erbium als Reaktorgift eine Absenkung des Peakfaktors der Leistungsverteilung im Kern erlaubt. Gleichzeitig erfordert der Restwert des Erbiums am Ende eines Brennstoffzyklus eine höhere Anreicherung des Brennstoffs. Als Fazit werden die positiven Erwartungen an die Nutzung von Erbium zusammengefasst.
