Monte Carlo simulations have been carried out to investigate microscopic surface structures during chemical reduction of a transition metal oxide, AO (A=Ni, Co, Fe, Mn), in which oxygen is immobile and cations are mobile via cation vacancies. The reduction is controlled by diffusion of cation...

The international OECD/NRC BWR Full-size Fine-Mesh Bundle Tests (BFBT) benchmark, based on the NUPEC database, encourages advancement in sub-channel analysis of two-phase flow in rod bundles, which has great relevance with regard to the nuclear reactor safety margin evaluation. This benchmark...
