METHOD OF AND DEVICE FOR ELIMINATING TOXIC MATERIALS Russian patent published in 1996 - IPC

FIELD: elimination of toxic materials by means of nuclear expositions. SUBSTANCE: cavity preorganized in rock salt mass is filled with toxic chemical materials and reagents that disintegrate chemical materials and turn them into solutions or solid harmless materials under the action of high temperatures built up by nuclear explosion; to this end, nuclear device is placed in cavity, holes providing communication between cavity and earth surface are sealed; mass of toxic chemical materials M_tchm and strength of rock salt bed H_bed are found from equation M_tchm≅α(V_o),β,E_o,M_rg=γ•M_tchm,H_bed≥60•F1/3o

, where α(V_o) is factor depending on cavity volume V_o; β is factor depending on proportion and type of structural materials and type of toxic chemical materials, t/kt; g is factor depending on type of toxic chemical materials; E_o is nuclear explosion power, kt of trotyl equivalent. EFFECT: facilitated procedure. 6 cl, 1 dwg
