Heat load analysis on the cable-in-conduit with central core conductor for the TF coil Rebut layer design
- Massachusetts Inst. of Tech., Cambridge, MA (United States)
The current Rebut Layer Design for the ITER TF coil calls for a cable-in-conduit with central core conductor, representing a break from the conventional configuration. In an effort to find the maximum heat load which this conductor can sustain without instigating quench, a model was developed to characterize the heat transfer behavior of the core. This model approximates the superconducting strands as double-sided fins exposed to two separate, parallel liquid helium flows. The model successfully predicts a reasonable value of maximum heat load, and yields results that compare well with a preliminary, computational analysis. The double-sided fin model also provides information on how such geometric parameters as core-to-cable space area ratio and strand winding angle can be adjusted to improve the heat transfer performance of the conductor. Experimental verification of the model is needed to insure compatibility with actual designs.
