Final cleansing of the PIVER prototype vitrification facility -Decontamination of the hot-cell; Assainissement final de l`installation prototype de vitrification PIVER. Decontamination de la cellule chaude

Abstract

Dismantling of the PIVER pilot vitrification facility began in 1984. Under a first contract FI 1D - 0057 with the European Community, all the process equipment was removed from the cell and decontamination was undertaken. The residual in-cell irradiation level was less than 10 mGy.h{sup -1} by the beginning of 1990, allowing brief access of operators to the cell for specific tasks. The cell cleanup work was completed in 1990; the telemanipulators were dismantled, and biological shielding was set up around a few remaining localized hot spots. By the end of the year, the in-cell dose rate had dropped to below 0.2 mGy.h{sup -1}. Research and development work on final decontamination processes was conducted from January to July 1991. Four already developed processes (electrolytic, shotpeening, cryogenic and gel) were tested under hostile radioactive conditions on a representative facility to assess their advantages and drawbacks, their effectiveness, and any points requiring special attention for large-scale application. The final decontamination operations were carried out on only a portion of the cell wall ; they did not significantly reduce the overall ambient irradiation level in the cell.
