摘要
The system and method (10) for safely isolating radioactive material (M) in an emergency situation includes a borehole (20) located in close proximity and at a depth sufficient for safe isolation of the material (M). In one embodiment, no external power supply is required. In another embodiment, a full casing bore hole (20) with a barrier on the bottom (25) is used to form a dry hole that can safely isolate hot material (M) without the risk of causing a steam explosion. To do. In the embodiment used for the isolation of contaminated water (W), the borehole casing (21) is perforated and the perforation (23) intersects a permeable area where water (W) can flow easily. In yet another embodiment, the gravitational crack is located at the bottom end (25) of the borehole (20) and the radioactive material (M) enters the gravitational crack. The dense slurry or fluid can be mixed with the radioactive material (M) to form and expand gravity cracks upon disposal of the radioactive material (M).
