“…One of the candidates is the combined electrolysis and catalytic exchange (CECE) process [1][2][3][4] which was practiced for detritiation of the moderator of a heavy water nuclear reactor and is developing in order to be applied to the tritium waste management. Another is the combination of electrolysis and cryogenic hydrogen distillation which has carried out the detritiation of heavy water used in a CANDU reactor [5,6]. Particularly, the last process serves also the tritium production.…”
