Establishment of benchmark problems for TRU fission rate ratios of FCA-IX assemblies

Fukushima, Masahiro ; Oizumi, Akito ; Iwamoto, Hiroki ; Kitamura, Yasunori

In the IX-th experimental series in 1980's at the fast critical assembly (FCA) facility, central fission rate ratios for TRU such as $^{237}$ Np, $^{238}$ Pu, $^{242}$ Pu, $^{241}$ Am, $^{243}$ Am and $^{244}$ Cm to $^{239}$ Pu were measured in the seven uranium-fueled assemblies with systematically changed neutron spectra. In the present report, benchmark problems with respect to central fission rate ratios were established for the assessment of the TRU's fission cross sections. We reported the sample calculation results on the benchmark problems by using JENDL-4.0.
