This comprehensive publication presents a detailed overview of the insights and outcomes gathered during a series of technical meetings conducted by Member States currently operating CANDU-type nuclear power plants. A significant focus is placed on fostering future harmonization in the regulatory framework, level 1 PSA methodologies and tools, and level 1 PSA scope. Furthermore, valuable information is shared regarding the actions taken in response to the lessons learned from the Fukushima Daiichi accident.

The meetings, held in various locations, brought together experts from different countries who operate CANDU-type nuclear power plants. These experts shared their experiences, challenges, and best practices related to the operation and regulation of these plants.

One of the key areas of emphasis was the need for future harmonization in the regulatory framework for CANDU-type nuclear power plants. The participants recognized the importance of maintaining a consistent and uniform approach to safety and security across all Member States operating these plants. They discussed potential areas for collaboration and coordination to achieve this goal, including the development of common standards, guidelines, and regulations.

Level 1 PSA methodologies and tools were also discussed in detail. The participants emphasized the importance of using reliable and validated methodologies to assess the safety and security of CANDU-type nuclear power plants. They discussed the development and improvement of existing tools, as well as the adoption of new technologies and approaches to enhance the accuracy and reliability of PSA assessments.

Level 1 PSA scope was another important topic of discussion. The participants recognized the need to expand the scope of PSA assessments to include all potential hazards and risks associated with the operation of CANDU-type nuclear power plants. They discussed the development of a comprehensive risk management framework that covers all aspects of plant operations, including maintenance, training, and emergency response.

In addition to the technical discussions, the publication also includes information on the actions taken in response to the lessons learned from the Fukushima Daiichi accident. The participants shared their experiences and insights on how the accident impacted the operation and regulation of CANDU-type nuclear power plants. They discussed the steps taken to enhance safety and security, including the implementation of new regulations, the development of emergency response plans, and the improvement of communication and coordination among stakeholders.

Overall, this comprehensive publication provides valuable insights and outcomes from the technical meetings of Member States currently operating CANDU-type nuclear power plants. It highlights the importance of collaboration, harmonization, and continuous improvement in the regulatory framework, level 1 PSA methodologies and tools, and level 1 PSA scope. The information shared on the actions taken in response to the Fukushima Daiichi accident further reinforces the commitment of Member States to enhance the safety and security of CANDU-type nuclear power plants.
