Uncertainty analysis of infinite multiplication factor and nuclide number density based on the UAM-PWR benchmark with respect to cross sections, fission yields and decay half-life

Modeling of changes in the nuclide composition of VVER reactor fuel using artificial neural network

“…When the macroscopic cross-sections decrease the cross-sectional area within which the neutrons travel also decreases. It gradually slows down the increase in the neutron flux, just to keep the desired power level of the reactor [ [6] , [12] ] (see Fig. 4 ).…”
