Calculation of nuclear reactivity using the generalised Adams-Bashforth-Moulton predictor corrector method
-
D. Suescún-Díaz
Abstract
In this paper, the generalisation of the 4th-order Adams-Bashforth-Moulton predictor-corrector method is proposed to numerically solve the point kinetic equations of the nuclear reactivity calculations without using the nuclear power history. Due to the nature of the point kinetic equations, different predictor modifiers are used in order improve the precision of the approximations obtained. The results obtained with the prediction formulas and generalised corrections improve the precision when compared with previous methods and are valid for various forms of nuclear power and different time steps.
Kurzfassung
In diesem Beitrag wird vorgeschlagen, die generalisierte Adams-Bashforth-Moulton Prädiktor-Korrektor-Methode der 4. Ordnung für die numerische Lösung der punktkinetischen Gleichungen bei Reaktivitätsberechnungen zu verwenden. Wegen der Natur der punktkinetischen Gleichungen werden verschiedene Prädiktor-Modifier verwendet, um so die Genauigkeit der Näherungsverfahren zu erhöhen. Die mit den Prädiktor-Formeln und den generalisierten Korrektoren erhaltenen Ergebnisse verbessern die Genauigkeit verglichen mit vorhergehenden Methoden und sind gültig für verschiedene Formen der Kernenergie und verschiedene Zeitschritte.
