Research Features

We are engaged in research on innovative nuclear reactors that reduce social and environmental risks by enhancing safety and nuclear security characteristics. Based on risk assessments of abnormal events that could be caused by malicious human activities, measures to improve inherent safety and nuclear security characteristics are being studied, and optimization design methods for nuclear reactors, including extrinsic measures such as nuclear material protection and safety protection, are being investigated. Furthermore, as research to ensure public confidence in the use of nuclear energy and improve transparency, we are applying advanced approaches such as deep learning models to develop advanced min methods and low-cost, reliable min techniques for identifying the origin of nuclear materials and radio-isotopes (RN materials), We are also working on the development of concepts that will contribute to improving the traceability of RN materials.

Research Overview

  1. Development of innovative nuclear reactors with reduced social and environmental risks
    Aiming to realize innovative nuclear reactors with reduced risk to society and the environment by optimizing safety and nuclear security characteristics, we are evaluating nuclear thermal stability and mechanical and chemical safety of nuclear reactors against abnormal events caused by malicious human actions, and examining optimization design methods for nuclear reactors based on these evaluations. The optimization of extrinsic measures such as safety protection, safeguards, and nuclear material protection, which are complementary approaches to the intrinsic characteristics that are difficult to modify artificially based on the fuel and core design approach, is conducted from the starting point to optimize the efficiency and economy of the extrinsic measures, including safety and nuclear security characteristics, to realize innovative nuclear reactors with safety and nuclear security characteristics and the synergy of these characteristics. The ultimate goal of the project is to propose an optimization approach to realize innovative nuclear reactors with safety and security characteristics and synergies between these characteristics.
  2. Research on Traceability Improvement of Nuclear Materials and Radioisotopes by "Nuclear Forensics
    Based on the knowledge of "nuclear forensics technology" that clarifies the history of nuclear and radioactive materials, we propose measures and means to improve the traceability of nuclear materials and radioisotopes (RN materials), which are indispensable for the sustainable development of modern society, and to increase the "transparency" in the use of RN materials. This research is aimed at improving the traceability of nuclear materials and radioisotopes (RN materials). This research will not only reduce the risk of nuclear proliferation and nuclear security by making military diversion and criminal use of RN materials more difficult, but will also contribute to the efficiency of international safeguards and physical protection measures, and to the response to contingencies beyond the design assumptions of nuclear power systems. This research contributes to the advancement, cost reduction, and reliability improvement of nuclear forensic
    min approaches by applying advanced approaches such as deep learning models, and by proposing traceability improvement measures that package tracer additives that facilitate the detection and identification of RN materials and their detection and measurement methods, Our ultimate goal is to contribute to the promotion of the social use of RN substances.
