Schematic of EVOLVE first wall and blanket.

Advanced Power Extraction (APEX) Study

The intent of the Advanced Power EXtraction (APEX) Study is to identify and explore novel, possibly revolutionary, concepts for chamber technology that might: enable plasma experiments to more fully achieve their scientific research potential; substantially improve the attractiveness of fusion as an energy source; and lower the cost and time for R&D.
In order to achieve high power density and high power conversion efficiency in future fusion plants, several first wall and blanket features are required. High power density means the coolant heat removal capability must be significant and high power conversion implies that the first wall and blanket must operate at high temperatures. The EVOLVE (EVaporation Of Lithium and Vapor Extraction) concept was developed to address these specific issues. It uses the vaporization of liquid lithium to remove heat from the fusion system.
