Safety of radioactive waste repositories operation is associated with a multibarrier system designed and
constructed to isolate and contain the waste from the biosphere. Each of radioactive waste repositories is equipped
with system of barriers, which reduces the possibility of release of radionuclides from the storage site. Safety
systems may differ from each other depending on the type of repository. They consist of the natural geological
barrier provided by host rocks of the repository and its surroundings, and an engineered barrier system (EBS).
The EBS may itself comprise a variety of sub-systems or components, such as waste forms, canisters, buffers,
backfi lls, seals and plugs. The EBS plays a major role in providing the required disposal system performance.
It is assumed that the metal canisters and system of barriers adequately isolate waste from the biosphere. The
evaluation of the multibarrier system is carried out after detailed tests to determine its parameters, and after
analysis including mathematical modeling of migration of contaminants. To provide an assurance of safety of
radioactive waste repository multibarrier system, detailed long term safety assessments are developed. Usually
they comprise modeling of EBS stability, corrosion rate and radionuclide migration in near fi eld in geosphere
and biosphere. The principal goal of radionuclide migration modeling is assessment of the radionuclides release
paths and rate from the repository, radionuclides concentration in geosphere in time and human exposure to
ionizing radiation.
