UNDERGROUND BURIAL FOR STORING RADIOACTIVE WASTE MATERIALS Russian patent published in 1996 - IPC

FIELD: environment protection. SUBSTANCE: burial is to be built in permafrost ground. The operation spaces of the workings, where containers with radioactive waste materials are placed, are in the area of continuously spread fusing permafrost at a depth satisfying a relation of H₁> H_ac+ R_o/H₂< H_pf- R_o, where H₁ is the depth of the upper part of the working operation space, H₂ is the depth of the lower part of operation space, H_ac is the lower boundary of the permafrost ground layer, H_pf is the upper boundary of the permafrost ground layer, R_o is the maximum size of operation space heat compensation zone. Distance L_i between the neighboring workings is selected to satisfy a relationship , where R_oi is the size of each operation space heat compensation zone. EFFECT: enhanced reliability of the burial. 2 dwg
