Diversion path analysis for the Swedish geological repository
2008 (English)Report (Other academic)
The Swedish strategy to handle the spent fuel from the nuclear power plants isthe direct disposal in a geological repository. The safeguards regime covering allnuclear material in the state will be expanded to cover the new repository, whichwill require a novel safeguards approach due mainly to the inaccessibility of thefuel after disposal. The safeguards approach must be able to provide a high levelof assurance that the fuel in the repository not diverted, but must also be resourceefficient. An attractive approach with regards to use of resources is to monitoronly the access points to the repository, i.e. the openings. The implementationof such an approach can only be allowed if it is shown to be sufficiently secure.With the purpose of determining the applicability of this “black box” approach, adiversion path analysis for the Swedish geological repository has been carried out.The result from the analysis shows that all credible diversion paths could be cov-ered by the black-box safeguards approach provided that the identified boundaryconditions can be met.
