| Purpose of this facility |
disposal of contaminated soils at site of NPP, migration
of radionuclides in the soil (contaminated soil in simulate
natural conditions, testing ignite or zeolite sorption
layers, compressed and non-compressed soil behaviour testing) |

| Future developments |
Long term testing of radiocesium and radiostrontium
in soil horizont in natural rainfall regime, monitoring
of the effectiveness of the sorbent layer, dependence
of radionuclide vertical migration in soil on the soil
treatment (non-compessed condition) |
