Seismic qualification of complex equipment by combined analysis and testing

Vilho Jussila, Ludovic Fülöp

    Research output: Book/ReportReport


    This report is deliverable for 2014 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 2014, in Subproject 3, the review task for an emergency diesel generator day-tank has been carried out and reported. 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, staring 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. The use in testing for results from the modelling are indicated further, and testing options for certain components of the day-tank are discussed.
