Neutronic integral benchmark experiments on DDX for fusion reactor design by OKTAVIAN

To investigate adequacy and accuracy of measured data and evaluated DDX data file, several Integral Benchmark Experiments have been done for Spherical and Slab Assemblies etc. of Fusion Materials on Tritium Breeding Ratio and Neutron Transmission by OKTAVIAN. The results indicate necessity of further elaborate experimental works in this field, for reliable neutronic design, e.g., TBR in Fusion Reactor Blanket. Appendices show our latest measurements of DDX for several nuclides at a fixed neutron energy. (14.1MeV) and studies on DDX for PKA in radiation damage analysis. (author)
