Numerical Analysis and Optimization of Divertor Cooling System

Authors: Andrei Khodak, Michael A. Jaworski

Abstract: Novel divertor cooling system concept is currently under development at Princeton Plasma Physics Laboratory (PPPL). This concept utilizes supercritical carbon dioxide as a coolant for the liquid lithium filled porous divertor front plate. Coolant is flowing in closed loop in the T tube type channel. Application of CO2 eliminates safety concerns associated with water cooling of liquid lithium systems, and promises higher overall efficiency compared to systems using He as a coolant.
