Resumen : | The viability of a fusion reactor is preeminently
conditioned by the tritium self-sufficiency. An assessment
of different parameters representing the tritium production,
as the Tritium Breeding Ratio (TBR), the Tritium
Production Rate (TPR) density and their poloidal and
radial variations along the PbLi breeder zones has been
performed for the last DCLL DEMO designs developed in
the frame of the EUROfusion Programme. The final overall
value of 1.104 obtained allows accomplishing the fuel selfsufficiency
requirement. This TBR value includes not only
the contribution of the Breeding Blanket (BB) modules but
also of the Back Supporting Structure (BSS). The BSS
design resulted fundamental to reach the 1.1 criterion.
Lastly, the influence of the integration in the reactor of the
heating and current drive (H&CD) systems that will
penetrate the breeder volume has been evaluated.
Assuming different configurations for them, the TBR loss
has been determined. All the calculations have entailed the
use of the particle transport Monte Carlo code MCNP5. |
