Olkiluoto was selected as a site for final disposal for spent fuel from Finnish nuclear power stations.At present the first underground tunnel for bedrock characterisation at repository site is being excavated. Theapplication for the nuclear construction permit should be submitted by the operator as early as 2012. Accordingthe current plans the construction of the encapsulation plant and the final repository will start around 2014. Theoperation of the facility will start in 2020. The final disposal facility, I.e. an encapsulation plant and anunderground repository, represents a new type of nuclear facility and new safeguards requirements need to beset. Safeguards measures of STUK are based on the national legislation and regulations as well as Finland'sinternational commitments. The main safeguards objectives at the pre-operational phase are: 1) Generation of theverified as-build design data and 2) Assessment of all available safeguards relevant monitoring data to assure theabsence of undeclared nuclear activities at or near the repository. In order to fulfil these requirements theimplementing company is obligated to report the excavation plans and progress and monitoring reports timely toSTUK, which assesses the information also performs safeguards inspections at the site. At operational phaseverification of as-built design will continue. Concerning nuclear materials Finnish national requirement is thatspent fuel will be comprehensively verified prior encapsulation followed with robust C-o-K methodologies overthe whole encapsulation and disposal process. Finnish SSAC invites the IAEA to make full use of its functionsand findings. It would be beneficial if the IAEA and the State had binding, but flexible, implementationarrangements to ensure that the IAEA safeguards needs are effectively met.
