Tóm tắt
Steady state Superconducting Tokamak (SST-1) to address some of the physics and technology issues related to steady state tokamak operation. The plasma facing components (PFC) of SST-1, placed inside the vacuum vessel (VV) of the tokamak, are designed to be compatible for steady state operation. The main consideration in the design of the PFC is the steady state heat removal of up to 1 MW/m/sup 2/. In addition to remove high heat fluxes, the PFC also arc designed to be compatible for high temperature baking. The thermal responses of the PFC and VV during their bakeout phase have been calculated analytically and with a 2D finite element analysis using ANSYS. The detailed analysis of radiation losses between the PFC and VV and the thermal-hydraulics of PFC baking are presented.
