Popis: A ‘Round Robin’ test of the European Commission 's “Repository Systems Simulation Test” has been undertaken. This involved testing an inactive simulant of the French high-level waste glass SON68 (RTT7) in containers which also held backfill, geological materials and water. Ten laboratories undertook the granite option, six salt and three clay. The test procedure was closely specified and is given in detail in a companion paper [1]. Experiments with glass powder and (optionally) solid specimens in contact with aqueous solutions were run for periods of up to one year at 90 °C and the solutions were analysed for Si, B, Li and Mo (compulsory) and other constituents of the corroded glass (optional). The analytical results are used to compare the performance of the glass under conditions representing those that might occur in future repositories in the three media.
