Original Abstract

The influence of the thermal conductivity on the development of the core temperatures during LOCA type accident is investigated in this article. At first, the RELAP5 model of the PSB VVER-1000 facility was validated against the experimental from the 11% upper plenum LOCA test. After validation, the model was modified in such a way that the heating rod geometry was changed to regular fuel pin based on the TVSAT-T fuel assembly design. With the modified model, a series of simulations was run in order to see the influence of burnup and SiC additive on the development of the cladding surface temperatures during LOCA accident.
