Lognormal-Based Sampling for Fission Product Yields Uncertainty Propagation in Pebble-Bed HTGR

Figure 17

Multiplication factor predictions with operation time. Operation time involves a running-phase (0–2500 days) and equilibrium core state (3049 days). The multiplication factor prediction differences of V.S.O.P. built-in yields and ENDF/B-VII.1 posterior yields are plotted.
