Presentation and Discussion of the UAM/Exercise I-1b: “Pin-Cell Burn-Up Benchmark” with the Hybrid Method Table 10 Uncertainty in number density of some important fission products. Cross-section uncertainties are taken from SCALE6.1/44-GROUP (
XS). Fission yields (
FYs) and decay data (
DD) source of uncertainty from JEFF-3.1.1.
