Abstract
PROCEDIMIENTO Y APARATO PARA ESTABILIZAR UNA ENVOLTURA (18) EVITANDO SU DESVIACION LATERAL. EL DESLIZADOR DE RETENCION DE ENVOLTURA (50, 50'') TIENE UNOS MUELLES QUE EJERCEN FUERZAS ORIENTADAS AL INTERIOR, OPUESTAS A LA DESVIACION LATERAL. CADA ESTABILIZADOR INCLUYE UN MUELLE DE PRECARGA Y UNO DE RETENCION SISMICA, CON BRAZOS ELASTICOS (62A, 62B, 64A-64D) CONECTADOS CON LAS EXTREMIDADES OPUESTAS DE UN ELEMENTO DE SOPORTE COMUN (60). LOS BRAZOS ELASTICOS DEL MUELLE DE PRECARGA FORMAN UN PRIMER MUELLE DE LAMINA DE RIGIDEZ RELATIVAMENTE PEQUEÑA Y LOS DEL MUELLE DE RETENCION SISMICA, UN SEGUNDO MUELLE DE LAMINA DE RIGIDEZ MAS IMPORTANTE. LAS RIGIDECES SE CONSIGUEN DANDO AL PRIMER MUELLE DE LAMINA UNA BASE MAS LARGA QUE LA DEL SEGUNDO. LAS ALMOHADILLAS (68A-68D) DEL MUELLE DE RETENCION SISMICA CONTACTAN CON LA VASIJA A PRESION DEL REACTOR, PERO NO SE PRECARGAN DURANTE LAS CONDICIONES DE FUNCIONAMIENTO. EL MUELLE DE RETENCION SISMICA SE CARGA RESPONDIENDO A LA DESVIACION LATERAL DE LA ENVOLTURA, POR EJEMPLO EN CASO DE FENOMENO SISMICO.
