NUMO underwent an international review by OECD/NEA (Organization for Economic Co-operation and Development / Nuclear Energy Agency) to assess the technical reliability of NUMO’s Pre-siting SDM-based Safety Case (English version PDF) from a global perspective. To disseminate the review findings and outline NUMO's future endeavors in response, an online technical briefing on geological disposal technology was held on June 8, 2023.
Approximately 200 individuals participated in the briefing, where Ms. Rebecca Tadesse from OECD/NEA provided insights into the background and methodology of the international review. Following this, Mr. Jussi Heinonen, the Chair of the International Review Team, presented an overview of the review results. NUMO then outlined its responses to the recommendations made in the evaluation and discussed future initiatives.
Courtesy of OECD/NEA, the materials used in the briefing are now available on NUMO's website, alongside additional resources. The video recording of the event, as well as responses to questions posed during the briefing and those submitted afterward, is now availabe on NUMO's website. https://www.youtube.com/watch?v=1grzKbf4NGE
Taking into account the recommendations outlined in the review report, NUMO will continue its efforts in developing safety cases and related technological advancements and provide ongoing updates on the progress and outcomes.
We sincerely apologize for any inconvenience caused by technical difficulties experienced during the briefing.
