| Summary: | The potential of a catalyzed (D, D) fusion-driven hybrid blanket is investigated for the regeneration of light water reactor spent fuel. Total enrichment grade is 2.172 % at beginning of regeneration. The hybrid blanket has excellent neutronic performance and is investigated to achieve different cumulative fission fuel enrichment (CFFE) grades. A regeneration period of up to 36 months is investigated by a plant factor of 75% under a first wall catalyzed (D, D) fusion neutron current load of 10 14. Neutron (14.1 MeV)/cm 2. s and 10 14 neuton (2.45 MeV)/cm 2. s. This corresponds to a first wall load of 2.64 MW/m 2. Regeneration periods of 12, 20, 28 and 36 months are considered, resulting in final enrichment grades of 3.0, 3.5, 4.0, and 4.5 %, respectively. The blanket energy multiplication M is quite high and increases only by ~ 30 % in 36 months. The electricity production remains fairly constant during this period. Consequently, this power exploits the non-nuclear island very well. At the same time, the peak-to-average fission power density ratio ? decreases by ~10 %. |
