          Abstract

          In this study, the steady and transient neutronic behaviour of MYRRHA ADS is investigated. For this purpose, a recently proposed analytical benchmark of the diffusion kinetics as 1D slab model of the MYRRHA ADS concept developed in Belgium has been extended to the cylindrical geometry which represents the system more realistically. Analytical calculations are performed using the Customized Solution Method and numerical Laplace inversion techniques such as Fixed-Talbot and Gaver-Wynn-Rho algorithms. Results are compared with the finite element program FLEXPDE® and they are found to be in complete agreement. The necessity of modeling the MYRHHA reactor in cylindrical geometry rather than slab geometry to obtain more realistic benchmark results is demonstrated.

          Kurzfassung

          In diesem Beitrag wird das Neutronenverhalten des beschleunigerbetriebenen Reaktors MYRRHA untersucht. Dazu wird eine kürzlich vorgeschlagene analytische Bewertung der Diffusionskinetik in eindimensionaler Stabgeometrie zur Modellierung des in Belgien entwickelten MYRRHA ADS Konzepts erweitert zu einer Zylindergeometrie, die das System realistischer darstellt. Analytische Berechnungen wurden durchgeführt unter Verwendung der Customized Solution Methode und numerische Laplace Inversionsverfahren, wie z.B. Fixed-Talbot und Gaver-Wynn-Rho Algorithmen. Die Ergebnisse werden verglichen mit dem finite Elemente Programm FLEXPDE® und stimmen miteinander überein. Die Notwendigkeit den MYRRHA Reaktor besser in Zylindergeometrie als in Stabgeometrie zu modulieren, um realistischere Benchmark Ergebnisse zu erhalten, wird demonstriert.
