Read messageOn behalf of the organizer of this conference, the Japan Atomic Energy Agency (JAEA), I welcome all those involved in the criticality safety research and development to the 12th International Conference on Nuclear Criticality Safety. I strongly hope that this conference, which will be held in Japan for the first time in 20 years, will facilitate the exchange of ideas among criticality safety researchers from all over the world and contribute to strengthen the further development of this field, following the last conference in Tokai-mura, Japan in 2003. JAEA has been the center of nuclear research and development in Japan since 1956, when its predecessor, the Japan Atomic Energy Research Institute (JAERI) was established, and has been involved in a wide range of research activities. Criticality safety assessment is a fundamental technology for nuclear energy utilization. JAEA has maintained quite a few facilities for the criticality experiment, and has continued to develop the reactor physics calculation codes and the evaluated nuclear data libraries, which are essential for criticality safety assessment. JAEA has played a role as a world leading R&D center contributing to criticality safety research. Despite the development of computer simulation technology, the importance of understanding the criticality characteristics of the nuclear material through experiments cannot be overstated. For the new task of handling the fuel debris generated by the accident at TEPCO's Fukushima Daiichi NPP, JAEA is tackling the modification of the criticality experiment apparatus “STACY” aiming to validate the criticality safety evaluation method for fuel debris. As a completely new evaluation target is about to be added to the criticality safety evaluation, it is a great honor for JAEA to host this international conference on the criticality safety in Sendai, the central city of the Tohoku region, which is now undergoing a major recovery from the Great East Japan Earthquake in March 2011. As the comprehensive nuclear research and development organization in Japan, JAEA considers this conference to be of great significance. We look forward to meeting you in Sendai, Japan, a beautiful city with green, in October 2023. Sincerely,
National Research and Development Agency, Japan Atomic Energy Agency Executive Director, Hiroyuki OIGAWA, Ph.D. |
Read messageWelcome to ICNC2023. It is our great pleasure to organize the 12th International Conference on Nuclear Criticality Safety ICNC2023, held in Sendai, Japan on October, 2023. This is the third conference held in Japan, after Tokyo, 1987 and Tokai-mura, 2003. The last ICNC in Japan, ICNC2003 was hosted by JAERI (Japan Atomic Energy Research Institute, the predecessor of JAEA (Japan Atomic Energy Agency)) and AESJ (Atomic Energy Society of Japan), and co-hosted by JNC (Japan Nuclear Cycle Development Institute, the predecessors of JAEA). ICNC 2023 is organized by JAEA and co-organized by Reactor Physics Division of the AESJ, and OECD/NEA(Nuclear Energy Agency). ICNC has been held every 4 years, and provided a great opportunity for the communication among researchers, engineers, plant operators, students and regulators related to criticality safety. We look forward to welcoming you to an attractive city, Sendai, for an enjoyable stay and a fruitful conference. Sincerely,
Kyoto University Professor, Ken NAKAJIMA |

NanoTerasu and Onagawa Nuclear Power Plant NanoTerasu is the next-generation synchrotron radiation facility that enables visualization in the nanoscale world. The emittance is about 1 nmrad in 3 GeV beam energy with a compact ring circumference of about 350 m and it is one of the brightest synchrotron radiation facilities in the world. Construction of the facility began in 2019, and operation is scheduled to start in 2023. The Onagawa Nuclear Power Plant is a boiling water reactor and has been in operation since 1984. It was the closest nuclear power plant to the epicenter of the Great East Japan Earthquake in 2011, but the operating reactors automatically shut down and were safe. Currently, preparations are underway to restart operations.

STACY and FCA in JAEA Static Experiment Critical Facility (STACY), which was a homogeneous system using solution fuel, had been used to measure the critical volume of low enriched uranium nitrate solution under various conditions from 1995-2011. The STACY is being renovated to a heterogeneous thermal core in order to satisfy new demands for critical experiments of thermal neutron systems. Its first criticality will be achieved in 2023. Fast Critical Assembly (FCA) is the country’s only critical assembly for the study of the neutronic characteristics of fast reactors. Its operation started in 1967, and the FCA experiments have made significant contributions to the development of fast reactors by providing experimental data.
