Abstract

PROCEDIMIENTO PARA LA LIMPIEZA DE CIERTAS ZONAS INACCESIBLES DE CIRCULACION REDUCIDA, EN EL LADO SECUNDARIO DE UN GENERADOR NUCLEAR DE VAPOR. COMPRENDE LAS SIGUIENTES OPERACIONES: PRIMERA, SE CALIENTA EL INTERIOR DEL LADO SECUNDARIO DEL GENERADOR DE VAPOR Y SE ELEVA LA TEMPERATURA DE LA SOLUCION ACUOSA DE AGENTE DE LIMPIEZA ORGANICO, MEDIANTE EL PASO DEL FLUIDO CALIENTE A TRAVES DEL LADO PRIMARIO DEL GENERADOR DE VAPOR; SEGUNDA, SE REDUCE LA PRESION EN EL LADO SECUNDARIO DEL GENERADOR DE VAPOR MANTENIENDO AL MISMO TIEMPO DICHO CALENTAMIENTO, PARA PROVOCAR LA RAPIDA VAPORIZACION LOCALIZADA Y LA EBULLICION DE LA SOLUCION ACUOSA DEL AGENTE DE LIMPIEZA.
