摘要

Helical fusion power reactors have competitive advantages for steady-state operation because they use a currentless plasma. This paper presents the cooling concept of the indirectly cooled superconducting helical coil for the helical fusion reactor FFHR-d1. The helical coil consists of continuously wound aluminum-alloy-jacketed Nb₃Sn superconductors and intermediate metal plates that not only cool the conductor indirectly, but also support the electromagnetic force. The copper cooling panels are partially mounted in the stainless steel intermediate plate and cooled by cryogenic supercritical helium. The conductor is cooled by contact with the cooling panels through an insulation material with high thermal conductivity, such as a ceramic. Fundamental calculations show that this cooling concept is technically feasible. Experimental investigations yielded a candidate for the ceramic insulator with high thermal conductivity.
