MULTIBARRIER PRINCIPLE

The safety of all the phases of the final disposal process must be ensured before activities are started. When the final disposal operations comply with the safety requirements set by the authorities as well as the internal requirements of Posiva, the radioactive substances will not cause significant health risks to the residents of surrounding areas, even in potential accident situations.

The final disposal will be realized according to the multibarrier principle. This ensures that even if the isolation capability of some canisters was lost, the other barriers would limit and slow down the release of radioactive substances from the fuel contained in the canister. Even in such a case, the consequences for people and the environment would be insignificant.
