Advances in the Electrolysis of Tritiated Water

DIFFERENT TYPES OF SEPARATORS FOR THE ELECTROLYSIS OF TRITIATED WATER HAVE BEEN PREPARED AND EXPOSED TO ALPHA RADIATION DAMAGE. THE BEST RESULTS HAVE BEEN OBTAINED BY A SEPARATOR, PREPARED BY RESERVE-PHASE IN WATER OF A SOLUTION OF POLYSULPHONE AND TITANIUM TETRABUTYLATE IN N-METHYLPYRROLIDONE. AS A FUNCTION OF THE RATIO BETWEEN THE POLYMERIC BINDER (POLYSULPHONE) AND THE ACTIVE COMPONENT (TITANIUM OXIDE) THE BEHAVIOUR OF THE SEPARATORS CHANGE UNDER AN ELECTROLYTIC POINT OF VIEW, AFTER THE EXPOSURE TO ALPHA RADIATION UP TO 60 MRAD. THE BEST RESULTS HAVE BEEN OBTAINED WHEN THE CONTENT OF TIO2 IS CLOSE TO 6%. WITH DIFFERENT CONCENTRATIONS THE SEPARATORS RESIST LESS TO THE RADIATION DAMAGE. THE CHARACTERISATION OF THESE SEPARATORS HAVE BEEN COMPLETED BY TESTING THEM IN HIGH CONCENTRATED ALKALINE ELECTROLYTIC MEDIUM IN ALPHA ACTIVITY AND MEASURING BEFORE AND AFTER THE TESTS, THE MECHANICAL AND ELECTROLYTIC PROPERTIES.
