Properties of Titanium Sponge Bed for Tritium Storage

A TRF (Tritium Removal Facility) will be constructed at Wolsong Nuclear Generating station to remove the tritium from heavy water. Titanium sponge has been selected as suitable material for tritium product immobilization. This paper is a summary of the experimental results conducted for the various properties of the reaction between titanium sponge and hydrogen isotopes. The conditions for activation, hydriding and dehydriding were investigated. The factors such as initial gas pressure and the helium content in the gas stream influencing the hydriding rate of the bed were examined.
