Abstract

In a hot vitrification pilot plant, built and operated by ENEA at JRC-Ispra, several high-level waste borosilicate glasses were produced, three of which were delivered to the hot cell laboratory at JRC-Karlsruhe for characterisation. A description is given of the microstructural analysis before and after corrosion tests (using a modified SOXHLET MCC-5S procedure), the chemical analysis of the leachates by ICP-MS and ICP-OES and the electron microprobe chemical analysis of the gel layers. The compositions of the glass matrix, waste loading, gamma-activity and canister material are reported.
