AbstractAbstract
[en] The closure of the container includes optical fibers the two ends of which are fixed perpendicular to a transparent seal containing a prism and a mask with alphanumeric characters. Light from a source is send through the system, in case of the container was broken open and the optical fibers put back in place a pattern different from the initial one will be obtained recording by a camera is possible

Practical decommissioning experience with nuclear installations in the European Community1992
Practical decommissioning experience with nuclear installations in the European Community1992
AbstractAbstract
[en] The cleaning an dismantling of the three hot cells in ORIS Industrie building are not very heavy operation. The surface of the work is reduced; so it is just possible to have only four or five operators at the same time. It is the reason for a long operation delay. The main technical difficulty of these operations consists in: - very high level of radioactivity measured on same apparatus (7000 rad on a press). They must be evacuated without disturbing the industrial production of ORIS Industrie. - putting of working area and the identification of relations between the different intervening parties

AbstractAbstract
[en] Over the years, France has built up significant experience in dismantling nuclear fuel reprocessing facilities or various types of units representative of a modern reprocessing plant. However, only small or medium scale operations have been carried out so far. To prepare the future decommissioning of large size industrial facilities such as UP1 (Marcoule) and UP2 (La Hague), new technologies must be developed to maximize waste recycling and optimize direct operations by operators, taking the integrated dose and cost aspects into account. The decommissioning and dismantling methodology comprises: a preparation phase for inventory, choice and installation of tools and arrangement of working areas, a dismantling phase with decontamination, and a final contamination control phase. Detailed description of dismantling operations of the MA Pu finishing facility (La Hague) and of the RM2 radio metallurgical laboratory (CEA-Fontenay-aux-Roses) are given as examples. (J.S.). 3 tabs
