We analyzed the Cost Of Electricity (COE) for an Inductively-Driven Long-pulse Tokamak (IDLT) reactor with the ARIES system code, and compared with a conventional pulsed tokamak reactor PULSAR-II design. To obtain ultra-long pulse operation for up to 〜 8 hours using only an inductive current drive, the major radius of the IDLT reactor should be increased up to 〜 10 m, while that of PULSAR-II is 〜 8 m with a pulse length of〜2 hours. In addition, the IDLT reactor has no energy storage system to compensate an electric power during dwell periods. It was found that the COE of IDLT reactor is 7% more than that of PULSAR-II, although the major radius is different between IDLT and PULSAR-II. This is because the fatigue problem is mitigated due to the reduction of the operation cycle number, and the power supply system is lightened due to the slow start-up of the plasma current. We should also remark that the maintenance scheme should be reconsidered in the IDLT reactor, because a single radial movement of blanket modules employed in the PULSAR design is difficult in large aspect-ratio devices such as the IDLT reactor.
