The test module coil (TMC-I) is the first test coil wound with multifilamentary Nb3Sn conductor in order to demonstrate high field superconducting toroidal field coils for fusion. The TMC-I was constructed in 1982 and the electrical, mechanical, and thermal characteristics were tested at the magnetic field of 10.2T by using the Cluster Test Facility (CTF). Thereafter, the TMC-I was successfully charged up to 11.1T in the Cluster Test Facility reinforced by adding two more back-ground coils (CBC) to the existing Cluster Test Coils (CTC). This paper describes thermal characteristics obtained in the cool-down, the heat load measurements, and the manual dump test of the TMC-I.
