One of the candidates is a low temperature immobilisation process to avoid volatilising radioactive Cs and Sr species. Detailed radionuclide volatilisation experiments were performed at Hitachi Research Laboratories in Japan, to investigate possible Cs volatilisation behaviour from commercial zeolitic adsorbents. Cs volatilisation was shown to be negligible, in most cases below detection limits, at temperatures below 600ºC, with volatilisation starting at 700 ºC and strongly increasing above 800ºC.

A zeolitic model wasteform, chabazite, was loaded with between 8-12 wt.% Cs waste loading and was sintered with two lead-based glass compositions, lead borosilicate (PBS) and a lead borate (PB) glass composition, at a maximum temperature of 600ºC.

PBS GCM formation was successful at a maximum of 500ºC, while the PB GCM formation was shown to be possible at a maximum temperature of 400ºC. Sintering optimisation undertaken has shown that the microstructure of the final wasteform can be finely tuned by controlling composition, sintering profiles and thermal treatment regimes. Sintering behaviour was shown to be independent of Cs waste loading of the adsorbent, but was shown to be strongly influenced by thermal treatment of the wasteform during sintering.
