Analysis of the vibrations of the internal structures of a water reactor

Description

The response of the ''basket'', shield and flow separation sleave of the reactor studied to flow-induced stresses was determined in two stages: study of the characteristic frequencies and associated characteristic modes, and estimation of the excitation force with calculation of the response. The calculation was carried out by applying the method of finite elements to shells in the form of figures of revolution using the Revomode code. The maximum displacement obtained is less than 1/10 mm

Abstract (French)

La reponse du panier, du bouclier et de la virole de separation des debits du reacteur etudie, aux sollicitations dues a l'ecoulement a ete decomposee en deux parties: la recherche des frequences propres et des modes propres associes et l'estimation de la force d'excitation avec calcul de la reponse. Le calcul a ete fait en utilisant la methode des elements finis appliquee aux coques de revolution dans le code Revomode. Le deplacement maximum obtenu est faible, inferieur au dixieme de mm
