Conclusion
The developed concept and the hands-on experience in steady-state operating
LM PFE creation and tests allows the solving a number of critical issues in the
development of appropriate PFE design that meet the requirements for long-
term operation at DEMO type tokamak conditions.
Tungsten fiber based CPS with lithium provides PFE surface protection and
renewal under expected power flux. Thin-walled cooling system ensures
maintenance of LM surface temperature at an appropriate level preventing
plasma pollution. The new composite structural material (67%W fibers + 33%
Eurofer steel) for the PFE first wall is presented to meet requirement in radiation
stability, thermal and stress capabilities. New type of coolant based on water-gas
spray is considered and proposed as more convenient coolant for lithium-
containing PFE that meet temperature limit and safety demands. All these points
allow to elaborate promising design of the DEMO divertor target plate.
