Progress of Thermal Shield for KSTAR; Design and Manufacturing

W. C. Kim, J. S. Bak, C. Mantileri and D. K. Kang

Abstract

Thermal shields for KSTAR (Korea Superconducting Tokamak Advanced Research) have been designed and are now under fabrication/installation. Thermal and mechanical analysis shows that the global temperature distribution of the thermal shields is within the designed value of 80 K and they withstand the mechanical loads under operation conditions and abnormal conditions. The assembly process has been designed to avoid any interference with adjacent components during tokamak assembly. Fabricating a prototype has proven the manufacturing feasibility, including forming of the shield panel and welding the tube on the panel. We report the details of engineering design, assembly procedure, and fabrication and installation progress.
