Formation of filtration fields in the near zone of radwaste storage facilities during decommissioning

Atomic Energy Aims and scope

Information is presented on the formation of filtration fields on sections of near-surface radwaste storage facilities with different degrees of degradation of engineered barriers. The initial geological-hydrogeological data for building models of filtration flow field formation near groups of storages facilities. Scenarios of the filtration field formation for decommissioning storage facilities are examined. It is shown that the restoration of engineered barriers to their initial state during decommissioning is a technogenic action which produces definite changes of the hydrogeological conditions on adjoining sections of the storage facilities. It is noted that restoration of the protective properties of a part of the facilities can result in the formation of secondary peripheral sections of radionuclide contamination. The character of the change in the hydrogeological conditions of the technogenic water-bearing horizon in the near-zone of storage facilities must be taken into account when taking corrective actions.
