Report

Generational variance reduction in Monte Carlo criticality simulations as a way of mitigating unwanted correlations

Autor: Fröhlicher, Kévin, Dumonteil, Eric, Thulliez, Loïc, Taforeau, Julien, Brovchenko, Mariya

Monte Carlo criticality simulations are widely used in nuclear safety demonstrations, as they offer an arbitrarily precise estimation of global and local tallies while making very few assumptions. However, since the inception of such numerical approa

Monte Carlo methods have been used for nuclear applications since the beginning of scientific computing. Decades of method refinements now allow to perform simulations of steady-state fissile systems with quite accurate results and relatively accessi
