Abstract

METODO DE DESCONTAMINACION DE SISTEMAS DE REFRIGERACION DE REACTORES NUCLEARES. COMPRENDE LAS OPERACIONES DE PASAR EL REACTOR Y AÑADIR UNA COMPOSICION DESCONTAMINANTE AL REFRIGERANTE DE SU SISTEMA DE REFRIGERACION; HACERLO CIRCULAR ENTRE UNA RESINA CAMBIADORA DE CATION Y EL SISTEMA DE REFRIGERACION HASTA QUE LA RADIACTIVIDAD EN EL REFRIGERANTE QUE SALE DEL SISTEMA NO ES MAYOR QUE LA DEL QUE ENTRA; SEPARAR LA COMPOSICION DESCONTAMINANTE MEDIANTE CIRCULACION DEL REFRIGERANTE POR UNA RESINA CAMBIADORA DE ANION; AÑADIR EL REFRIGERANTE OZONO, CERIO IV Y UN COMPUESTO AROMATICO SOLUBLE EN AGUA CON UN GRUPO CETONA; HACER CIRCULAR EL REFRIGERANTE HASTA QUE LA CONCENTRACION DE CROMO NO AUMENTA; ELEVAR SU TEMPERATURA HASTA 100JC; HACERLO PASAR A TRAVES DE UNA RESINA ANIONICA; LLEVAR LA TEMPERATURA A 60-200JC Y REPETIR LAS OPERACIONES ANTERIORES.
