Abstract

Water detritiation is important for protection of members of the public and the environment against tritium and for commercially feasible operation of the fuel cycle of industrial fusion reactor. Review of two main technologies for water detritiation at industrial scale reveals that combined electrolysis and catalytic exchange (CECE) is a more preferable option than water distillation. In this chapter, a review of thermodynamic equilibrium and mass transfer parameters for water detritiation is presented together with consideration of possible configurations for operation of water detritiation system in combination with isotope separation system. Different types of hydrophobic catalysts for liquid phase catalytic exchange (LPCE) column, as a key element of CECE technology, are described. Assessment of performance of LPCE column based on simplified approach or detailed computer model is also presented.
