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

<div>Relative difference of lognormal-based sampled independent fission yields mean values (blue dots) and STD (orange dots) to Bayesian updated values. The outlier fission products are (mean values) Ag130m0, Sn127m1, Cd126m0, In126m0, In118m1, Br86m1, and Ge75m0 and (STD values) Sb131m0, Ag130m0, Cd126m0, Sn122m0, and Br86m1.</div>
