Summary

Results of calculation of neutron-physical characteristics of model of spatial location of volumes of filled: by a concrete, metal and fuel contained materials with low and high fuel in fusion penetration area of fundamental flag of reactor shaft in south-east part of apartment 305/2 and in the areas of directly joining to the area fusion penetration, the mass and geometrical parameters of which answer the real terms of existence of the hidden accumulation are given. Possibility of description of dynamics of development and independent extinguishing of neutron anomaly, which was registered in 1990 is analyzed, depending on the possible sizes of parameters of heterogeneity of mixture of fuel contained materials with contains a lot of fuel.
