METHOD OF NON-CAVITY FILLING OF REACTOR SPACES WHEN DECOMMISSIONING URANIUM-GRAPHITE NUCLEAR REACTOR |
摘要 |
FIELD: processing and recycling of waste.SUBSTANCE: invention relates to technology of operation of uranium-graphite nuclear reactors. In compliance with method of no-cavity filling reactor spaces at reactor decommissioning as per version of on-site disposal selected is path of process channel, through which cavity will be filled in. Preliminarily prepared paths for free movement of screw. In selected channel screw pipe is inserted and screw is placed coaxially inside pipe. In nearest path of process channel vibrating boom is installed. Loose barrier material is fed into top of screw pipe. By means of screw under pressure barrier material is advanced in filled cavity. Simultaneously with help of vibration oscillations of vibrating boom and operation of screw conditions created for separation of formed "hill", material compaction, flotation around obstacles and walls.EFFECT: possibility to form solid security barriers with sufficient meagreness for sorption and limitation of migration of radionuclides at decommissioning of uranium-graphite nuclear reactor as per on-site version of disposal.2 cl, 1 dwg |
