PROCESS OF CRASHED ATOMIC REACTOR ENTOMBMENT Russian patent published in 2008 - IPC G21F9/24 

FIELD: physics; construction.

SUBSTANCE: process of crashed atomic reactor entombment includes construction of underground mortuary in the form of vertical underground excavation. Internal volume of the excavation is filled with ice which forms a new temporary ice foundation under the basis of the crashed reactor. The weight of the latter is shifted to the new ice foundation, heat is conducted to it, and gradually the height of ice foundation is decreasing till the complete removal of ice. At that, the crashed reactor is set at the mortuary made previously at the basement of excavation. Before deposition of the crashed reactor underground, solidity (thickness) of frozen soil body under the reactor basis is improved, and then, after the new ice foundation is ready, the load is increased, and the previous ground base is destroyed by adjoining of excavation ice body to the crashed reactor basis via flexible load-bearing cables laid through the vertical wells.

EFFECT: reduces amount of work in immediate proximity to a crashed atomic reactor.
