Figure [BIASU] Simulation of the R1 configuration with 104 active generations and 104 neutrons per generation. Left plot: relative estimated (“apparent”) 1- uncertainties (%), right plot: true 1- uncertainties estimated with independent simulations (%). Figure [BIASU2] Simulation of one pin-cell of the R1 configuration with reflective boundary conditions on all edges. Left plot: true 1- uncertainties estimated with independent simulations (%), central plot: relative estimated (“apparent”) 1- uncertainties (%), right plot: ratio between true and apparent uncertainties. nSRC is the number of neutrons per generation and nCA is the number of active cycles. Figure [STC] The UO2 pin-cell is divided into twenty cells (from cell 1 at one extremity to cell 20 at the other extremity). First line, from left to right: cycle to cycle flux correlations in cells 1, 5 and 10 respectively. Second line, from left to right: cell to cell correlations with temporal lags of 0, 50 and 200 respectively. Figure [CLUS] Left plot: Simulation with 1000 cycles and 1000 neutrons per cycle of the UO2 fuel pin with reflective boundary conditions. Right Plot: Simulation with 1000 cycles and 105 neutrons per cycle of the UO2 fuel pin with reflective boundary conditions. nSRC is the number of neutrons per generation and nCycle is the overall number of cycles.
