Modeling of Pore Coarsening in the Rim Region of High Burn-up UO2 Fuel
An understanding of the coarsening process of the large fission gas pores in the high burn-up structure (HBS) of irradiated UO2 fuel is very necessary for analyzing the safety and reliability of fuel rods in a reactor.

A study into the propagation of the uncertainties in nuclear data to the nuclear concentrations of nuclides in burn-up calculations [PDF]
The key papers on estimating the uncertainties in nuclear data deal with the influence of these uncertainties on the effective multiplication factor by introducing the so-called sensitivity factors and only some of these are concerned with the influence ...
