摘要
FIELD: nuclear power engineering. SUBSTANCE: for decrease of harmful effects of emergency object on people and for increased reliability of burial underground burial ground is created under object where object is moved and heat liberated by object is withdrawn. Vertical shaft and horizontal adits towards center of object are constructed at safe distance from reactor. Cooling and heating sources are installed in adits, ground of foundation of object is reinforced in advance by drilling of inclined boreholes with placement of thick-walled casing pipes and by freezing of this ground with the aid of source of cold. Then underground working fixed with lining is created uniaxially to object above adit. Heat exchangers connected to specified sources of heat and cold are positioned inside working, internal space of working is filled and water is frozen, ground under object is unfrozen, casing pipes are removed out of inclined boreholes and vertical boreholes are drilled up to ice over perimeter of object. Then feed of coolant is stopped and heat-transfer agent is supplied into heat exchangers of foundation of working. As ice thaws and object sinks water created under these conditions is evacuated. EFFECT: improved safety of burial of ecologically hazardous objects. 2 cl, 1 dwg
