FIELD: transport.SUBSTANCE: group of inventions relates to feeding solution into container accommodating hazardous wastes, in particular nuclear wastes. In the method, solution is fed into container immovably connected with the first and the second reservoirs. The first reservoir communicates with container via the first hole, the second reservoir - via the second one. In this process, solution flow is subjected to forced continuous circulation in circulation circuit. During this circulation, the second flow of solution is drawn which is less intensive than the first flow, and delivered to container. Solution appearance in the second reservoir is detected. When this appearance is detected solution bleeding from circulation circuit is terminated. Device for implementation of the method contains solution circulation circuit consisting of vessel for solution storage, pump for solution transfer connected with the vessel, source pipeline to transfer solution exiting the pump, return pipeline to transfer solution to the vessel, and discharge pipeline following the source pipeline. The device also contains the first and the second reservoirs immovably connected with container against holes made in its wall, and sensor detecting solution appearance in the second reservoir. In this structure, circulation circuit contains bleeding device connecting source, return and discharge pipelines, and cutoff of discharge pipeline from the circuit is performed by on-off valve installed at the inlet of discharge pipeline. Herewith, source and return pipelines provide continuous solution circulation, and bleeding device provides drawing part of solution flow circulating in the circuit and its delivery to discharge pipeline.EFFECT: group of inventions provides better container filling when there is no reliable information on wastes volume in it, and better insulation.18 cl, 4 dwg |
