Essay

Physical and mathematical models were developed and thermal calculation of LFCM formation process on upper marks of destroyed ChNPP Unit 4 was carried out. These estimates have shown that, on the upper marks of destroyed Unit 4 not less than 15 tons of LFCM are localized. A scenario was offered, how areas with high uranium content in premises 305/2 had produced. Thy probability of deep cavity formation in sub-reactor solid plate filled with FCM with high uranium content was grounded. A model of area with high uranium content in southern part of premise 305/2 south-east quadrant was developed. The mass parameters of above area were estimated. It is shown that sub-reactor solid plate, in quadrant 46/47, И/К, includes FCM clusters with probable maximum uranium concentration making 30 % and more
