摘要

核聚变可以提供清洁、丰富的能源。然而,如何管理从核心聚变等离子体向反应堆壁消耗的能量仍然是一个重大挑战。这种情况在新兴的紧凑型反应堆设计中更加复杂,有望实现更具成本效益的商业聚变能源。替代导流器配置(adc)是一种潜在的解决方案。在这项工作中,我们展示了adc的排气控制,采用一种新的方法来诊断中性气体缓冲,从而屏蔽目标。我们在百万安培球形托卡马克升级上的工作表明adc解决了核聚变能源的关键风险和不确定性。它们对扰动的敏感性大大降低,可以在不可行的情况下进行主动排气控制,并有助于增加瞬态的被动吸收,否则会损坏导流器。我们观察到每个分流器与其他反应堆区域的强解耦,使分流器和堆芯等离子体的控制几乎独立。我们的工作展示了adc在聚变反应堆中有效热负荷管理的实际好处。

Demonstration of Super-X divertor exhaust control for transient heat load management in compact fusion reactors

Demonstration of Super-X divertor exhaust control for transient heat load management in compact fusion reactors
Nuclear fusion could offer clean, abundant energy. However, managing the power exhausted from the core fusion plasma towards the reactor wall remains a major challenge. This is compounded in emerging compact reactor designs promising more cost-effective pathways towards commercial fusion energy. Alternative Divertor Configurations (ADCs) are a potential solution. In this work, we demonstrate exhaust control in ADCs, employing a novel method to diagnose the neutral gas buffer, which shields the target. Our work on the Mega Ampere Spherical Tokamak Upgrade shows that ADCs tackle key risks and uncertainties for fusion energy. Their highly reduced sensitivity to perturbations enables active exhaust control in otherwise unfeasible situations and facilitates an increased passive absorption of transients, which would otherwise damage the divertor. We observe a strong decoupling of each divertor from other reactor regions, enabling near-independent control of the divertors and core plasma. Our work showcases the real-world benefits of ADCs for effective heat load management in fusion power reactors. Managing power exhaust in fusion reactors is a key challenge, especially in compact designs for cost-effective commercial energy. This study shows how alternative divertor configurations improve exhaust control, enhance stability, absorb transients and enable independent plasma regulation.
