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

Figure 8

Lognormal distribution of random variable in terms of its relative uncertainty. Relative uncertainty is ranged from 10% to 80% and . Dashed line shows the distribution with relative uncertainty lower than or equal to 40%, whereas solid line indicates the distribution with relative uncertainty larger than 40%.
