NEA conference focuses on new nuclear development
More than 300 delegates from around the world attended the OECD Nuclear Energy Agency’s recent Roadmaps to New Nuclear 2025 conference in Paris, France. In attendance were representatives from governments, industry, public and private financial sectors, academia, legal firms, think tanks, and research institutions. Cohosted by the Korean government, the event focused on practical, near-term solutions to barriers facing nuclear new builds.

The next few years bring the exciting prospect of new reactor designs achieving commercial operation with a diversity of technology and quantity that has not been seen for decades. With this new opportunity comes an old challenge - initial core design. These designs tend to be distinct from standard reloads in their fuel composition, which can lead to cycle-specific safety analysis and core management constraints. The fuel in initial cores must also support a range of new reactor commissioning and startup testing that can add requirements for flexibility and robustness through the first cycle of operation. At the same time, these startup tests provide a unique opportunity for validation of core management code systems through comparisons of model predictions against measured results. This panel will provide an opportunity to learn from recent experience in developing and implementing initial core designs and startup testing campaigns through a series of short presentations followed by a question and answer session.
