Concerns when designing a safeguards approach for the back-end of the Swedish fuel cycle

In Sweden, the construction of an encapsulation plant and a geological repository for the final disposal of spent nuclear fuel is planned to start within the next ten years. Due to Sweden’s international agreements on non-proliferation, the Swedish safeguards regime must be extended to include these facilities. The geological repository has some unique features, which present the safeguards system with unprecedented challenges. These features include, inter alia, the long period of time that the facility will contain nuclear material and that the disposed nuclear material will be very difficult to access, implying that physical verification of its presence in the repository is not foreseen.
This work presents the available techniques for creating a safeguards system for the back-end of the Swedish nuclear fuel cycle. Important issues to consider in the planning and implementation of the safeguards system have been investigated, which in some cases has led to an identification of areas needing further research.
The results include three proposed options for a safeguards approach, which have been evaluated on the basis of the safeguards authorities’ requirements. Also, the evolution and present situation of the work carried out in connection to safeguards for geological repositories has been compiled.
