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 ID 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 Gayer-Wynn-Rho algorithms. Results are compared with the finite element program FLEXPDE(R) 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.
