Description

In year 2006 we started data processing from the Dukovany NPP operating history database that contained data from the old measurement system VK3 and the new Scorpio-WWER. The work has been done in cooperation with the reactor physicists at Dukovany NPP. Obtained data from database were compared with calculated parameters from 3D diffusion macrocode MOBYDICK. During the data processing it was found that the Gd fuel assemblies have different time plot of measured assembly outlet temperature compared to the non-Gd fuel assemblies. The consequent analyses were focused on the detailed outlet temperature comparison of Gd and non-Gd fuel assemblies during their whole in-core life cycle. In near future it is planned to develop calculation methods for the correction of measured assembly outlet temperature. Consequently, the correction methods will be implemented to the modernized Scorpio-WWER for Dukovany NPP (Authors)
