Abstract

SISTEMA ANTIDESPEGUE PARA REACTORES NUCLEARES. CONSTA DE UN ORGANO INSERTABLE (14) QUE TIENE DOS JUEGOS DE RESORTES DE LAMINAS (23) QUE TRANSMITEN A UNOS ENSAMBLAJES (10A, 10B) UN EMPUJE QUE PROVIENE DE UNA ESTRUCTURA SUPERIOR CONSTITUIDA POR UNA PLACA SUPERIOR DEL CORAZON DEL REACTOR. ESTOS MEDIOS ELASTICOS ESTAN INSCRITOS EN LA SECCION RECTA DEL ENSAMBLAJE (10) HASTA SU INTRODUCCION POR LA ESTRUCTURA COMUN QUE PROVOCA EL DESPLIEGUE DE LOS ORGANOS ELASTICOS. EL ORGANO INSERTABLE TIENE UN RESORTE (39) DE TRANSMISION DEL ESFUERZO EJERCIDO SOBRE LA ESTRUCTURA COMUN AL ENSAMBLAJE (10) EQUIPADO CON EL ORGANO.
