摘要

In recent years, there has been a growing interest in developing high-fidelity reactor physicscalculations, for both stationary and transient (operational and accidental) behavior. In thiscontext, the H2020 McSAFE project represents a collaborative effort led by 12 institutionsfrom 7 EU countries to provide reliable and efficient numerical tools for the simulation ofgeneration 2 and 3 light water reactors (LWR). In order to meet this challenge, several newmajor features are under development for Monte Carlo codes to be able to simulate nonstationaryneutron transport with and without thermal-hydraulic feedbacks. Within thisframework, in the present work a series of transient scenarios with reactivity insertions dueto control rod movement for a 3D PWR Minicore benchmark are proposed and analyzed.Simulations are obtained based on the Serpent and TRIPOLI-4? Monte Carlo codes, wherekinetic capabilities have been recently (and independently) developed. The respectiveresults are compared to each other in order to assess the accuracy of non-stationarysimulations on realistic configurations. Running times, convergence and foreseenrequirements are also briefly discussed.
