The technological features of manufacturing process for RF CHC TBM

The development of manufacturing technology for the ceramic helium-cooled test blanket module (CHC TBM) is performed in the framework of the concept for RF Federal government program to master the fusion nuclear energy and as a part of the development of DEMO blanket technology. The main technical approach to the development of CHC TBM manufacturing technology is to provide the “combined” analogy with design decisions of DEMO blanket structural elements. The manufacturing technology of CHC TBM structural elements (first wall cramp, load-bearing back cramp, tritium-breeding element and attachment system) has been proposed during the period of 2004–2007. The design details of TBM structural elements and critical issues of manufacturing technology development are also presented in this paper.
