Abstract

An original dissolution method for irradiated Li2TiO3in aqueous H2O2was developed. One could easily obtain fine Li2TiO3powders from the solution through drying and calcination. Li2TiO3pebbles (size ∼0.6 mm, above 90% TD) were obtained from the 'reprocessed' powders. These solutions were also suitable for the formation of a sol emulsion in 2-ethyl-hexanol-1, from which gelled microspheres of lithium titanate could be obtained. Locally prepared Li2TiO3reprocessed and supplied pebble batches were tested for tritium release by temperature programmed desorption (TPD) methods in He + 0.1%H2(R-gas) after their short irradiations in a thermal neutron flux. The relative TPD data were compared. A qualitative correlation was developed between peak characteristics and pebble microstructure. © 2001 Elsevier Science B.V.
