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

<div>Neutron induced fission process [<a href="/journals/stni/2020/8014521/#B21">21</a>]. The fission products refer to the fission fragments after the emission of prompt neutrons. Independent fission yields (IFYs) characterize the fraction of a fission product produced before any radioactive decay, whereas cumulative fission yields (CFYs) describe the fraction of that produced product over all time after a fission.</div>
