| The goal of this technical report is the estimation of the neutron-induced fission fragment
productions using the most recent optimized design of the converter-fission target assembly.
Calculation of the fission yields has been done using evaluated yields for the fission products
tabulated at three energies of the neutron field. This approach was checked by an alternative
method that uses CINDER to determine fission production rates. In-target fission yields were
further derived and discussed for six isotopes of interest and six fission target configurations.
The report provides detailed fission yields distributions for selected relevant nuclides and
discuses the potential of the investigated target material configurations to enhance the
production of specific nuclear species.
A comparative study between the two production scenarios used in the design, converter
and direct methods, in terms of neutron and fission rate distributions and relevant fission
product yields is finally carried-out. The results clearly confirm that the two production
systems are complementary allowing at the same time to have a picture of the figure of merit
of the future facility. |
