提出了一个示范托卡马克聚变电站Demo-CREST，作为早期实现聚变能净发电的装置。Demo-CREST的等离子体配置进行了优化，以满足电气盈亏平衡条件（净电功率的条件）与ITER参考操作模式的等离子体性能。这种优化方法被认为是适合的示范电厂的设计，以早日实现净发电，因为示范电厂必须确保净发电。等离子体性能也应该比过去的设计研究更可靠地实现。对于目前ITER计划中计划的等离子体性能，在以下工程条件下，Demo-CREST可以实现0至500 MW的净电功率：最大磁场16 T，热效率30%，NBI系统效率50%，NBI电流驱动功率限制在200 MW。通过用热效率更高的系统替换覆盖层系统，也可以获得约1000 MW的净电功率，从而也可以从经济角度研究具有Demo-CREST的商业设备的性能。作为快速轨道概念的一个例子，提出了从实验堆“ITER”到商业工厂“CREST”，通过示范电厂“Demo-CREST "的发展路径。
A demonstration tokamak fusion power plant Demo-CREST is proposed as the device for early realization of net electric power generation by fusion energy. The plasma configuration for Demo-CREST is optimized to satisfy the electric breakeven condition (the condition for net electric power, ) with the plasma performance of the ITER reference operation mode. This optimization method is considered to be suitable for the design of a demonstration power plant for early realization of net electric power generation, because the demonstration power plant has to ensure the net electric generation. Plasma performance should also be more reliably achieved than in past design studies. For the plasma performance planned in the present ITER programme, net electric power from 0 to 500 MW is possible with Demo-CREST under the following engineering conditions: maximum magnetic field 16 T, thermal efficiency 30%, NBI system efficiency 50% and NBI current drive power restricted to 200 MW. By replacing the blanket system with one of higher thermal efficiency, a net electric power of about 1000 MW is also possible so that the performance of the commercial plant with Demo-CREST can also be studied from the economic point of view. The development path from the experimental reactor ‘ITER’ to the commercial plant ‘CREST’ through the demonstration power plant ‘Demo-CREST’ is proposed as an example of the fast track concept.
