Plasma simulation and modeling for ELMO bumpy torus reactor

A time-dependent deuterium-tritium point model was formulated to assess the energy balance in an ELMO Bumpy Torus Reactor (EBTR) plasma. The effects of the different scaling assumptions on EBTR performance and operating point were analyzed. Although in the present EBT device (EBT-I) plasma transport seems to be governed largely by neoclassical processes, hypothesized anomalous transport losses are included in the plasma simulation model in addition to neoclassical and for classical transport in order to test the sensitivity of EBTR parameters. For the particular case studied, it is shown that the reference EBTR can accommodate anomalous losses one to two orders of magnitude greater than the present neoclassical losses at the operating point (steady state). Results are discussed.
