OECD Nuclear Energy Agency

Next week, government and industry leaders will gather at Roadmaps to New Nuclear 2024 conference to discuss concrete ways to make good on global objectives to increase #nuclear energy production to fight climate change and assure energy security. 💡 Co-chaired by Sweden's Deputy Prime Minister and Minister for Energy, Business and Industry, Ebba Busch, and OECD Nuclear Energy Agency's Director-General William D. Magwood, IV, this meeting will focus on collective practical steps to assure that new nuclear build can be accomplished effectively and at the scale required to meet the objectives of countries that expect nuclear energy to play a significant role in their #energy futures. 🌍⚛️ #RoadmapsToNewNuclear Learn more 🖱️ www.oecd-nea.org/roadmaps

For almost two-and-a-half decades, the OECD Nuclear Energy Agency's 𝗙𝗼𝗿𝘂𝗺 𝗼𝗻 𝗦𝘁𝗮𝗸𝗲𝗵𝗼𝗹𝗱𝗲𝗿 𝗖𝗼𝗻𝗳𝗶𝗱𝗲𝗻𝗰𝗲 (FSC) has served as a platform to build understanding and enhance stakeholder engagement in the fields of radioactive waste management, decommissioning and legacy management. 🗯️ To progress on these themes, the NEA organised the FSC Swedish National Workshop focused on Dialogue and Transparency When a Site and Method are Licensed. Hosted by the Swedish Radiation Safety Authority (SSM) and municipality of Östhammar from 23-24 September 2024 in Sweden, the workshop included discussions on the present and future role of SSM in stakeholder engagement to further explore topics raised by research projects. The workshop also featured meetings with community members in Östhammar, which was chosen as the site for Sweden’s geological repository in 2009, and high school students from Östhammar Vattenfallsgymnasiet were invited to share their views.

🌧️ The concept of local intense precipitation (LIP) has been widely used in flood risk assessments for #nuclear installations, but it is not well defined in the literature. To characterise LIP for nuclear installations, the OECD Nuclear Energy Agency is seeking to bring together key information and the best available technical approaches and methods. In this context, the NEA in collaboration with the Ontario Power Generation organised an international workshop in Toronto, Canada, to discuss LIP and its impacts on nuclear installations. Workshop sessions explored: ➡️ Key issues and knowledge gaps in tackling the LIP impact on nuclear installations ➡️ Historical trends in extreme precipitation and estimating methods ➡️ Design storms, probabilistic flood hazard assessment and potential LIP effects on nuclear power plants ➡️ Protection and mitigation procedures ➡️ Climate change issues related to LIP phenomena and the use of climate change models The NEA will publish the workshop proceedings, including final conclusions and recommendations for follow-up activities.

This week in Hungary: Safety Case Symposium 2024 💬 Organised by the OECD Nuclear Energy Agency, the symposium focuses on advancing the construction of safe deep geological repositories (DGRs) for high-level radioactive waste. The four-day event was opened by Dr Márk Alföldy-Boruss, Deputy State Secretary of Ministry of Energy of Hungary, and NEA Director-General William D. Magwood, IV. With numerous national programmes advancing towards licensing and realising their #DGRs for high-level radioactive waste, this symposium offers a vital platform to discuss the evolution and implementation of safety cases, featuring insights from international programmes at various stages of development. 🌍 More information 🖱️ https://lnkd.in/eDgGdNxZ

Advancing the understanding of fuel safety issues: 2️⃣5️⃣ years of international collaboration 🌎 The OECD Nuclear Energy Agency, through its Working Group on Fuel Safety (WGFS), seeks to advance current understanding and address cross-cutting issues related to fuel behaviour in accident conditions, including work on associated aspects of thermal-hydraulics, oxidation, chemistry, mechanical behaviour and reactor physics. Experts recently convened for the 25th WGFS annual meeting in Paris. Former WGFS chairs and many long-serving members rejoined the current delegates to reflect on the past, celebrate the achievements of the group and discuss future activities. Members exchanged information on the status of their national nuclear industries, research activities and regulatory frameworks related to nuclear fuel and heard updates about ongoing NEA joint projects related to nuclear fuel.

Happening next week 📅 Preparatory webinar for the fourth 𝗡𝗘𝗔 𝗦𝘁𝗮𝗸𝗲𝗵𝗼𝗹𝗱𝗲𝗿 𝗜𝗻𝘃𝗼𝗹𝘃𝗲𝗺𝗲𝗻𝘁 𝗪𝗼𝗿𝗸𝘀𝗵𝗼𝗽 🗯️ Engaging with a wide range of stakeholders with different perceptions and expectations, also including civil society and non-governmental organisations, is essential in decision making related to nuclear energy activities such as new plant construction, decommissioning and waste disposal. 🏗️ To foster productive dialogue and collaboration among the nuclear sector representatives and society, the OECD Nuclear Energy Agency organises Stakeholder Involvement Workshops. Ahead of the fourth NEA Stakeholder Involvement Workshop, the NEA will hold preparatory webinars that will convene representatives from government institutions, industry, academia, NGOs and civil society from NEA member countries and beyond. The discussions during the first webinar will explore how to improve understanding of power imbalances that may occur when involving stakeholders in decision-making processes, and will examine key considerations for the nuclear sector. First preparatory webinar: 𝙀𝙣𝙨𝙪𝙧𝙞𝙣𝙜 𝘽𝙖𝙡𝙖𝙣𝙘𝙚𝙙 𝙋𝙤𝙬𝙚𝙧 𝙖𝙣𝙙 𝙄𝙣𝙛𝙡𝙪𝙚𝙣𝙘𝙚 𝘼𝙢𝙤𝙣𝙜 𝙎𝙩𝙖𝙠𝙚𝙝𝙤𝙡𝙙𝙚𝙧𝙨 📅 14 October 2024, 13:00-16:00 CEST 📍 Online More information and registration 👉 https://lnkd.in/eXYfu5zc Pictured 📸 NEA Stakeholder Involvement Workshop held in 2023
