Tore Supra的一个特点是面向等离子体的组件（PFC）是主动冷却的，允许研究长时间和高能量放电。在放电过程中，发热器（ICRH、ECRH和LHH）和辅助设备中消耗的大部分能量转移到主冷却回路（B50和B60）。注入等离子体中的能量被PFC主冷却回路B30完全回收。主回路通过热交换器由副回路冷却。完整Tore Supra冷却系统先前存在的局限性是由于二次回路的热交换性能。从2001年到2003年，各种初级回路已经升级，在2003年的实验活动中，取得了显着的成果，特别是在非感应放电与注入能量的低杂波电流驱动（LHCD）系统高达1.1GJ。对于长时间高能量放电，量热法测量的PFC释放的热能与注入等离子体的能量之间的一致性非常好（90-95%）。此外，对各种冷却回路的量热测量允许评估冷却系统的全局操作。
One particularity of Tore Supra is that the plasma facing components (PFCs) are actively cooled, allowing research on long duration and high energy discharges. During a discharge, a large part of the energy dissipated in the heating generators (ICRH, ECRH and LHH) and auxiliaries is transferred to the primary cooling loops (B50 and B60). The energy, which is injected in the plasma, is totally recovered by the PFCs primary cooling loop B30. The primary loops are cooled via heat exchangers by a secondary loop. The previously existing limitations of the complete Tore Supra cooling system were due to the heat exchange performance to the secondary loop. From 2001 to 2003, the various primary loops have been upgraded and during the 2003 experimental campaign, significant results were obtained, particularly during non-inductive discharges with an injected energy by the lower hybrid current drive (LHCD) system of up to 1.1GJ. For the long and high energy discharges, the agreement between the thermal energy exhausted from the PFCs and measured by the calorimetry and the energy injected in the plasma is very good (90–95%). Furthermore, calorimetry measurements on the various cooling loops allow to assess the global operation of the cooling system.
