  • Method and apparatus for the treatment of radioactive evaporator concentrates from nuclear plants
    Patent number: 6218592
    Abstract: A method for the treatment of radioactive evaporator concentrates from the evaporation system of nuclear plants comprises the steps of (a) freeing the evaporator concentrates from undissolved components, (b) crystallizing the sodium sulfate contained in the evaporator concentrates as Glauber's salt (Na2SO4.10 H2O) on an immersion cooler, (c) recrystallizing the Glauber's salt deposited on the immersion cooler, (d) optionally, repeating the recrystallization step (c) once or several times, (e) separating essentially inactive sodium sulfate from the process, and (f) recycling the depleted evaporator concentrates of step (a) to the evaporation system.
