The aim of the present study is to evaluate the structural effects induced by a severe flooding/tsunami on a SMR outer containment (e.g. the one of Westinghouse proposal) in agreement with the “stress tests” suggestions, presently foreseen by the European and International Associations and on basis of the lesson learnt from Fukushima accident. Therefore to evaluate the consequences induced by the breaking and splashing water waves on a SMR containment building, non linear analyses (by using adequate FEM codes) were performed simulating the water impact forces in terms of pressure, calculated on the basis of the water velocity and flow depth (according to the ASCE rules). The obtained results highlighted the tsunami effects are mainly dependent on the wave elevation, flow velocity, hydrodynamic phenomena and geometry of the reference structures. Finally they showed that the considered containment building seemed capable to withstand the flooding/tsunami applied forces without unbearable loss of the integrity of SMR containment structure(in the assumed geometries and material characteristics).

Abstract
The aim of the present study is to evaluate the structural effects induced by a severe flooding/tsunami on a SMR outer containment (e.g. the one of Westinghouse proposal) in agreement with the “stress tests” suggestions, presently foreseen by the European and International Associations and on basis of the lesson learnt from Fukushima accident. Therefore to evaluate the consequences induced by the breaking and splashing water waves on a SMR containment building, non linear analyses (by using adequate FEM codes) were performed simulating the water impact forces in terms of pressure, calculated on the basis of the water velocity and flow depth (according to the ASCE rules). The obtained results highlighted the tsunami effects are mainly dependent on the wave elevation, flow velocity, hydrodynamic phenomena and geometry of the reference structures. Finally they showed that the considered containment building seemed capable to withstand the flooding/tsunami applied forces without unbearable loss of the integrity of SMR containment structure(in the assumed geometries and material characteristics).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
