    Research output: Book/ReportReport


    This report is deliverable for 2013 of Subproject 3 in the project SESA "Seismic Safety of Nuclear Power Plants - Targets for Research and Education", part of the SAFIR 2014 program on nuclear safety. In 2013, in Subproject 3, the review task for an emergency diesel generator day-tank has been started according to the discussions in the Ad-Hoc group of SESA. The day-tank has been one configuration supplied by Wärtsilä, and loads were provided by TVO according to a realistic scenario for placement of the day-tank. The aim was to carry out modeling of the day-tank, starting with simple models and ending with very sophisticated liquid interaction models, in order to understand the limitations of the analysis methods usually used in the qualification process. In this stage loads were predefined for the day-tank scenario, but in the next stage some variability of the loading will also be considered. The main emphasis of Subproject 3 is in 2014 according to the multi-annual plan of the SESA project.
