Decomposition of Tritiated Water With Solid Oxide Electrolysis Cell

A new concept for decomposing tritiated water with a solid oxide electrolysis cell is proposed. This method is essentially free from problems such as large tritium inventory, radiation damage, and solid waste, so it is expected to be a promising one. Preliminary experiments with the cell using stabilized zirconia with 8 mol% CaO were performed. Water vapor was decomposed electrically and cell voltage agreed well with the theoretical value.
