Abstract

Procedimiento para incorporar sustancias residuales radioactivas, que contienen liquido, en material sintético termoplástico con ayuda de un dispositivo amasador, caracterizado porque el termoplástico se alimenta a temperatura ambiente al dispositivo amasador, porque el termoplástico se calienta en el dispositivo amasador a como mínimo 100ºC, porque al termoplástico calentado se le agregan los materiales residuales el termoplástico y los materiales residuales se mezcla entre sí a una temperatura incrementada de 100 a 200ºC y más, porque la mezcla se seca bajo mantenimiento de la temperatura en forma en si conocida por evaporación y porque la mezcla evaporada se extrae mecánicamente del dispositivo amasador.
