Summary of the IAEA technical meeting on plasma disruptions and their mitigation

This report summarizes the contributions presented at the IAEA technical meeting on plasma disruptions and their mitigation, held virtually, 20–23 July 2020. The meeting brought together more than 120 experts from nuclear fusion research sites worldwide to discuss experimental, theoretical and modelling work in the field of plasma disruptions with special emphasis on developing a solid basis for possible disruption mitigation strategies in ITER and next generation fusion devices. The main topics of the meeting were: (i) disruption consequences, including electromagnetic loads, heat loads, and runaway electrons; (ii) disruption prediction and avoidance, including machine learning and physics-based approaches, and control aspects; and (iii) disruption mitigation, including shattered pellet injection, alternative techniques and general aspects of disruption mitigation.本报告汇总了2020年7月20日至23日以线上形式举办的国际原子能机构（International Atomic Energy Agency，IAEA）等离子体破裂及其缓解技术专题技术会议的提交成果。本次会议汇聚了来自全球各地核聚变研究机构的120余名专家，围绕等离子体破裂领域的实验、理论与建模研究展开研讨，重点聚焦为国际热核聚变实验堆（International Thermonuclear Experimental Reactor，ITER）及下一代核聚变装置的破裂缓解策略开发夯实坚实基础。本次会议的核心议题包括：(i) 破裂后果：涵盖电磁载荷、热载荷与逃逸电子相关研究；(ii) 破裂预测与规避：涵盖机器学习方法、基于物理的方法及控制相关议题；(iii) 破裂缓解：涵盖碎裂弹丸注入技术、替代技术及破裂缓解的通用相关议题。
