Abstract

UN SISTEMA PASIVO DE INYECCION DE SEGURIDAD SE APOYA EN LAS DIFERENCIAS DE LA DENSIDAD DEL AGUA PARA INDUCIR PATRONES DE FLUJO DE CIRCULACION NATURAL QUE CONTRIBUYEN AL MANTENIMIENTO DE CONCENTRACIONES PRESCRITAS DE ACIDO BORICO EN AGUA BORATADA, Y EVITA QUE EL BORO SE ACUMULE EN EL RECIPIENTE (44) REACTOR Y POSIBLEMENTE EVITE LA TERMOTRANSFERENCIA.
