[en] The Fusion Engineering Design Center (FEDC) is focusing FY 1983 activities on evaluating upgrade alternatives for the major fusion device now being completed. FEDC resources are divided equally betweek tokamak applications, in support of TFTR upgrade, and tandem mirror applications, supporting upgrade of the MFTF-B facility. In the course of magnet system design studies related to these activities, several needs for water cooled copper coils are presently perceived. The applications discussed in this paper are the high field choke coils (tandem mirror) and toroidal field coils or coil inserts (tokamaks). In these applications, the important properties are low electrical resistance, high mechanical strength and tolerance to neutron fluence
