Abstract

UN METODO DE DETERMINACION DEL GRADO DE HUMEDAD EN CADA UNA DE UNA PLURALIDAD DE VARILLAS DE COMBUSTIBLE NUCLEAR MIENTRAS SON PROCESADAS PARA EXTRAER LA HUMEDAD EN UNA ESTUFA EN LA QUE SE HACE EL VACIO. EL VAPOR PROCEDENTE DE UNA VARILLA SELECCIONADA AL AZAR ES CONDENSADO EN UN SEPARADOR ENFRIADO POR NITROGENO LIQUIDO, Y DESPUES, PREFERIBLEMENTE, ES ABSORBIDO POR PERCLORATO DE MAGNESIO, CUYA VARIACION DE PESO ES DETERMINADA COMO MEDIDA DEL GRADO DE HUMEDAD DEL COMBUSTIBLE DE LA VARILLA.
