Title: Start-up of commercial high-level waste vitrification facilities at La Hague

Vitrification of high-level wastes has now entered an industrial phase. The new R7 and T7 vitrification facilities at La Hague integrate the latest technological innovations from a 30-yr program, which has demonstrated the safety, reliability, ease of operations, and maintenance of the AVM (Marcoule vitrification plant) process. The two vitrification facilities, R7 and T7, with a combined glass production capacity of 180 kg/h, will vitrify fission product solutions, dissolution fines, and sodium-rich solutions from the new UP2-800 and UP3 reprocessing plants at La Hague (combined throughput capacity of 1600 tonne U/yr). The main process components (e.g., the calciner and the melter) have been scaled up, the layout has been modified to enhance the overall availability of each vitrification line, and the maintenance technologies and control system architecture have been based on new developments for the UP3 reprocessing plant. Radioactive start-up of the R7 vitrification facility occurred on June 12, 1989. On June 20, 1989, nine glass canisters were produced under very good operating conditions. The second facility, T7, now undergoing cold testing, will be commissioned in early 1991.
