Research and development in nuclear reactor physics and thermal-hydraulics continue to
be vital parts of nuclear science and technology in Japan. The Fukushima accident not only …

The new version of the Japanese evaluated nuclear data library, JENDL-5, was released in
December 2021. This paper demonstrates the validation of JENDL-5 for fission reactor …

Accelerator-driven system experiments with spallation neutrons (100 MeV protons and Pb-Bi
target) are carried out in the 235 U-fueled and Pb-Bi-zoned core at the Kyoto University …

Designing reactor cores by means of an artificial neural network is a difficult challenge,
because there are many variables in the core configuration. Especially, for designing a new …

Basic research on the accelerator-driven system is conducted by combining 235 U-fueled
and 232 Th-loaded cores in the Kyoto University Critical Assembly with the pulsed neutron …

This open access book is a unique compilation of experimental benchmark analyses of the
accelerator-driven system (ADS) at the Kyoto University Critical Assembly (KUCA) on the …

Nuclear data-induced uncertainties of neutronics parameters (neutron multiplication factor
keff, one-point kinetics parameters and prompt neutron decay constant α) are quantified for …

To validate lead (Pb) nuclear cross sections, a series of integral experiments to measure
lead void reactivity worth was conducted systematically in three fast neutron spectra with …

To validate lead (Pb) nuclear cross sections, a series of integral experiments to measure
lead void reactivity worths was conducted in a high-enriched uranium (HEU)/Pb system and …

Sensitivity and uncertainty analyses of lead (Pb) isotope cross sections are conducted with
the use of sample reactivity experiments at the Kyoto University Critical Assembly (KUCA) …
