4. Conclusions

4.1 Lessons learned from the safety analysis conducted as part of the 2005 Dossier

The safety assessment shows that the radiological protection objectives have been met. In all cases, the dose is significantly below the reference value of 0.25 mSv · year ^–1 . The safety of the repository is based on a multi-functional concept, involving the site, the design provisions and the primary packages in a complementary manner, giving the repository a high degree of robustness. The altered evolution situations identified by the analysis are few in number and relate to a limited number of well-identified scenarios. These do not lead to a radiological impact significantly greater than that of the normal evolution scenario.
