N2 - It is argued that a full set of tests should subject the model coils for the ITER (International Thermonuclear Experimental Reactor) to a minimum of 40000 operating cycles. They describe a proposal to carry out such an extended performance cyclic test where the TF (toroidal field) and CS (central solenoid) model coils would be combined into a single test arrangement and the field cycled continuously every 1 to 4 min. They propose that the TF model coils be down-sized to a noncircular shape, 2 m3.5 m ID, and be operated as inserts in the CS model coils rather than tested in a stand-alone mode. Approximately four months of continuous cycling would be required for the life test, but it is likely that two years of elapsed time would be required to complete the tests. Near-continuous operation would also demonstrate the reliability of auxiliary cryogenic and power systems. To compensate for the loss of large coil fabrication experience with the down-sizing of the TF model coil, the authors propose that a full-scale double pancake of the ITER TF coil be fabricated from production conductor, and that it be cold tested in a prototypical 'Q/A Production Test'.
