Preface
The main objective of this book is to lead to a considerable emphasis on actual data
of the ADS experiments, showing mainly outstanding features of the KUCA facilities,
including two external neutron sources (14 MeV neutrons and 100 MeV protons) and
a variety of nuclear fuel materials (highly enriched uranium, thorium, and natural
uranium) and reflector materials (polyethylene, graphite, beryllium, aluminum, iron,
lead and bismuth), which play an important role in determining neutron spectrum of
the KUCA core.
The book has been organized into three parts with eight chapters and Appendix.
The authors present, firstly, kinetics parameters: subcriticality and delayed neutron
decay constant covering studies of measurement methodologies and correction
factors, in Chaps. 2–4. Secondly, the authors include static parameters: reaction
rates, nuclear transmutation of minor actinide (Np-237 and Am-241), neutronics of
Pb-Bi (Pb and Bi isotopes) that is a coolant material of actual ADS experimental
facilities, and sensitivity and uncertainty of criticality in the KUCA core, dedicating
studies of neutron spectrum, nuclear transmutation, sensitivity, and uncertainty, in
Chaps. 5–8, respectively. Thirdly, the authors provide all experimental data of
ADS carried out in the KUCA core so that many researchers should easily access,
compiling in Appendix.
The authors would like to acknowledge the assistance of a group of truly exceptional former students of Kyoto University, including Yoshiyuki Hirano, Hervault
Morgan, Hiroshi Shiga, Takahiro Yagi, Hesham Shahbunder, Hak Sung Kim,
Yuki Takemoto, Tetsushi Azuma, Hiroyuki Nakano, Kiichi Sukawa, Yoshimasa
Yamaguchi, Atsushi Fujimoto, and Makoto Ito, and former other research staff,
including Dr. Jae Yong Lim, Dr. Kyeong Won Jang, Dr. Thanh Mai Vu, and Dr.
Song Hyun Kim, carrying out successfully all the ADS experiments at KUCA and
demonstrating interestingly the experimental and numerical results.
It is particularly important to acknowledge the invaluable comments and fruitful
discussions with respect to a series of the ADS experiments at KUCA, of the members
of the ADS Coordinated (Collaborative) Research Projects (CRP) organized by the
International Atomic Energy Agency (IAEA) in 2004 through 2019, including Dr.
Alberto Talamo (Argonne National Laboratory: ANL, US), Dr. Mario Carta (Energia
Nucleare ed Energie Alternative: ENEA, Italy), Prof. Piero Ravetto (Politecnico di
Torino, Italy), Dr. Fabrizio Gabrielli (Karlsruhe Institute of Technology, Germany),
Prof. Chang Hyo Kim (Seoul National University: SNU, Korea), Prof. Mate Szieberth
(Budapest University of Technology and Economics, Hungary), Prof. Hyung Jin
Shim (SNU, Korea), Dr. Alexander Stanculescu (Idaho National Laboratory, US),
and Dr. Yousry Gohar (ANL, US).
The authors also wish to express our gratitude to Ms. Maki Nakatani and Ms.
Mari Yamahana of KURNS for their efforts in helping prepare the various drafts and
manuscripts.
