Abstract The present paper deals with the assessment of original and a modified version RELAP5/MOD3.3 against OSU Multi Application Small Light Water Reactor (OSU-MASLWR). new implemented features regard suitable correlations for heat transfer coefficient evaluation in helical geometry. Furthermore, two different modelling Helical Coil Steam Generator (HCSG) are assessed. In first approach, HCS...

This paper presents the complete algorithm of site response analysis of nonhomogeneous topographic structures using transient two-dimensional boundary element method (BEM). Seismic behaviour of various topographic features including canyon, half plane, sedimentary filled valley and ridge sections, subjected to incident SV and P waves are analysed. The analysis shows the efficiency of the propos...
