Blanket and Process Engineering / Proceedings of the Second National Topical Meeting on Tritium Technology in Fission, Fusion and Isotopic Applications (Dayton, Ohio, April 30 to May 2, 1985) / dx.doi.org/10.13182/FST85-A24602

The tritium technology needs for a Tokamak Demonstration Reactor (DEMO) have been reviewed and compared with the technology that will be developed from pre-DEMO experimental facilities. The Engineering Test Reactors, of either the tokamak or tandem mirror type, can provide most of the technology which can be safely extrapolated to the DEMO. Unresolved issues which need major attention are plasma-wall interactions, tritium barriers in the heat transfer system and tritium breeding in fusion reactor-relevant experimental facilities.
