This chapter describes the equipment referred to as breeding blankets that will be used in the next fusion reactors. The mechanisms occurring in such components are addressed, including simplified diagrams to illustrate their functioning. The breeding function for an industrial size machine - the next step after ITER - is crucial because tritium is not available in sufficient quantities on the earth's surface. Only mock-ups - Test Blanket Modules (TBM) - will be tested in ITER to demonstrate the tritium breeding function and to collect experimental data. The TBM are supported by processes aiming to recover the heat generated by the plasma operations and to recover the tritium produced by neutron bombardment. The first section of this chapter focuses on the various TBM concepts proposed by the members of the ITER experimental and scientific programme. Characteristics and expected performance levels are summarized and discussed. In the second section, the processes selected to support the TBM operations are described.

Abstract

This chapter describes the equipment referred to as breeding blankets that will be used in the next fusion reactors. The mechanisms occurring in such components are addressed, including simplified diagrams to illustrate their functioning. The breeding function for an industrial size machine - the next step after ITER - is crucial because tritium is not available in sufficient quantities on the earth's surface. Only mock-ups - Test Blanket Modules (TBM) - will be tested in ITER to demonstrate the tritium breeding function and to collect experimental data. The TBM are supported by processes aiming to recover the heat generated by the plasma operations and to recover the tritium produced by neutron bombardment. The first section of this chapter focuses on the various TBM concepts proposed by the members of the ITER experimental and scientific programme. Characteristics and expected performance levels are summarized and discussed. In the second section, the processes selected to support the TBM operations are described. The technical issues and/or technical locks regarding tritium technologies are then highlighted in the third and final section. © 2013 Nova Science Publishers, Inc. All rights reserved.
