ARC：一个紧凑的高场聚变核科学设施和示范发电厂，带有可拆卸磁铁
ARC: A compact, high-field, fusion nuclear science facility and demonstration power plant with demountable magnets
摘要：
负担得起的，鲁棒的，紧凑的（ARC）反应堆概念设计研究的目的是减少规模，成本和复杂性的组合聚变核科学设施（FNSF）和示范聚变试验电厂。ARC是一个200-250 MWe的托卡马克反应堆，长半径3.3 m，短半径1.1 m，轴上磁场为9.2 T。ARC有稀土钡铜氧化物（REBCO）超导环向场线圈，它有接头，使拆卸。这允许真空容器被快速更换，减轻第一壁存活性的担忧，并且允许单个装置测试许多真空容器设计和偏滤器材料。设计点的等离子体聚变增益为Qp ~13.6，但完全无电感，自举系数仅为~ 63%。因此，ARC提供高功率增益，具有相对较大的电流分布外部控制。这种极具吸引力的组合是由最新可用的REBCO超导技术线圈上的~23 T峰值磁场实现的。外部电流驱动由两个创新的内置RF发射器提供，使用25 MW的低混合动力和13.6 MW的离子回旋快波功率。由此产生的高效电流驱动提供了远离破坏性极限的鲁棒的稳态核心等离子体。ARC使用全液体覆盖层，由低压、缓慢流动的氟锂铍（FLiBe）熔盐组成。液体包层是低风险技术，提供有效的中子慢化和屏蔽，出色的散热，氚增殖率>= 1.1。FLiBe为液体的大温度范围允许在900 K下使用单相流体冷却和高效布雷顿循环进行毯式操作，从而允许在将ARC作为试验发电厂操作时进行净发电。
英文摘要：
The affordable, robust, compact (ARC) reactor conceptual design study aims to reduce the size, cost, and complexity of a combined fusion nuclear science facility (FNSF) and demonstration fusion Pilot power plant. ARC is a 200-250 MWe tokamak reactor with a major radius of 3.3 m, a minor radius of 1.1 m, and an on-axis magnetic field of 9.2 T. ARC has rare earth barium copper oxide (REBCO) superconducting toroidal field coils, which have joints to enable disassembly. This allows the vacuum vessel to be replaced quickly, mitigating first wall survivability concerns, and permits a single device to test many vacuum vessel designs and divertor materials. The design point has a plasma fusion gain of Q_p~13.6, yet is fully non-inductive, with a modest bootstrap fraction of only ~63%. Thus ARC offers a high power gain with relatively large external control of the current profile. This highly attractive combination is enabled by the ~23 T peak field on coil with newly available REBCO superconductor technology. External current drive is provided by two innovative inboard RF launchers using 25 MW of lower hybrid and 13.6 MW of ion cyclotron fast wave power. The resulting efficient current drive provides a robust, steady state core plasma far from disruptive limits. ARC uses an all-liquid blanket, consisting of low pressure, slowly flowing fluorine lithium beryllium (FLiBe) molten salt. The liquid blanket is low-risk technology and provides effective neutron moderation and shielding, excellent heat removal, and a tritium breeding ratio >= 1.1. The large temperature range over which FLiBe is liquid permits blanket operation at 900 K with single phase fluid cooling and a high-efficiency Brayton cycle, allowing for net electricity generation when operating ARC as a Pilot power plant.
