IAEA recomendation says that the minimization of radioactive wastes is also required in the decommissioning activities. In addtion, it is necessary to manage a risk depending on the progress of the dismantling activities. In this study, the methodology for the evaluation and the validation of the planning, conducting and the completion of the decommissioning will be sophisticated as follows.
- Modelling for optimization of reducing both of radioactive wastes arising and doses for worker and public, and developing the methodology
- Development of risk assessment methods during dismantling activities

| Summary | The candidate is expected to elucidate the influence of in-pile irradiation on the property of new fuel claddings, which will be used for not only accident tolerant fuel for light water reactor, but also for small modular reactor and for accelerator-driven transmutation system. A wide variety of tests such as micrstructural observation, mechanical strength (tensile, hardness measurement etc), high temperature oxidation, and corrosion will be conducted using the cladding materials which were irradiated under various environmental conditions. Based on the experimental data acquired, a correlation between changes in microstructure and mechanical properties in the materials and radiation damage behavior will be evaluated. Through these works, it is expected that synergistic function among environmental factors (irradiation, thermal load, stress, atmosphere etc) influencing on correlation evaluation for those materials will be clarified. |

| Summary | Chemical reactions and phenomena at the solid-liquid or liquid-liquid interfaces are often different from those of solution phase. In order to accurately predict the effects of radiation on living organisms and substances, it is important to clarify the mechanism of radiation-induced chemical reactions that occur at the interfaces. In this research theme, we will study the interface structure in an ultrathin region of about 1 nm by making use of sum frequency generation spectroscopy, which is an advanced laser spectroscopy method as an interface probe. By applying this method, we will try to elucidate the molecular structure change of the interface under X-ray irradiation. The subjects of the experiment are not only substances important for nuclear engineering such as nuclear fuel and metal materials, but also biomolecules aiming to create fundamental knowledge that leads to accurate prediction of radiation effects. |

| Summary | An accelerator consists of many piece of precision devices. Since then, the accelerator is only properly working, if all components are operated in strict synchronization. J-PARC is a multi-purpose accelerator complex and delivers beams for multiple destinations simultaneously. It is required to optimize the beam conditions for each beam destination. In addition, input timing and output data to the beam diagnostic system must be strictly controlled for each operation mode. In this theme, we conduct research and upgrading control system of not only beam diagnostics but also various instruments. We are also aiming to establish highly stable accelerator operation and high quality beam to all user facilities. We will develop a beam diagnostic instrument which is usable with high intensity beam, eliminating failure of timing, data archive system or free of failure, recording system for mal function or sign of machine failure. |

| Summary | We are developing water leak detectors for early detection of water leak events that occur in heat transfer tubes of steam generators in sodium-cooled fast reactors to suppress the spread of accidents. This system aims to achieve high reliability and detection performance by utilizing the phenomenon that hydrogen generated in the sodium-water reaction transmits through a Ni film installed in the gas and sodium. This development is a key issue in terms of feasibility of larger steam generators because it contributes to early detection of accidents and prevention of their spread. In the development, the behavior of hydrogen in gas and sodium is considered phenomenologically, and an algorithm to improve the signal-to-noise ratio that can identify hydrogen generated during a water leak event is developed through the use of computer chemistry and verification through testing at the Oarai Research and Development Institutes. The study will examine the behavior of hydrogen in sodium and gas (dissolved hydrogen atoms, dissolved hydrogen molecules, hydrogen bubbles, and hydrogen compounds) according to plant operating conditions and water leak events in heat transfer tubes, and analyze the behavior around the Ni film. The system will be constructed to enable highly reliable detection of minute leaks. The research scope will be considered according to the applicant's preference and experience. |

| Summary | As part of research on the creation of new technologies for liquid sodium, a fundamental study has been conducted focusing on the control of wettability between liquid sodium and substrate metals. So far, it has been clarified that the interatomic interaction at the interface between liquid sodium and substrate metal affects the wettability. Therefore, the purpose of this study is to obtain fundamental knowledge on wettability control technology by utilizing chemical reactions at the atomic level and changes in atomic bonds on the surface of metal that come into contact with liquid sodium. In particular in order to understand the factors of wettability control, various surface treatments are carried out to the substrate metal, and wettability with liquid sodium is evaluated by experiment. Furthermore, in order to clarify the cause of change, the substrate surface is analyzed using various analysis methods. Therefore, in addition to surface treatment technology, excellent knowledge about surface analysis technology is required to the doctoral research fellow. In addition, in order to deepen understanding of the evaluation by experiments, the analysis of the atomic interaction will be carried out from the theoretical calculation of the electronic state of the interface model, and the theoretical evidence will be obtained. |

| Summary | This R&D attempts to verify and establish a mid-and-long-term behavior estimation method for a hundred or several thousand years and to construct its deterioration model, and will contribute to selection of a method for managent of radioactive wastes arising from decommissioning operations. A wide variety of radioactive wastes have arisen from decommissioning of the Fukushima Daiichi Nuclear Power Station. These wastes need to be managed (storage, processing, disposal) for a certain period. It is not rational to obtain each data on the soundness and deterioration of a waste solidified product for all wastes, since characteristics of a waste solidified product changes according to properties of the wastes. |

| Summary | This R&D attempts to treat radioactive organic liquids containing uranium after evaluating characterization of them, and will contribute to the promotion of decommissioning of domestic nuclear facilities. Waste organic solvent and machine oil used in nuclear facilities have been stored, and it can be predicted that many research facilities will generate them according to decommissioning. It is considered that these organic solvents and the like have a negative impact on the landfill environment and are difficult to be solidified by using cementitious materials. Therefore, it is positioned as one of the wastes that is difficult to treat, and it is required to establish an appropriate processing method as the steam reforming treatment or the alkali activated materials (AAM) solidification. |

| Summary | Among the research and development on geological disposal technology, as part of the research on long-term stability of the geological environment, advanced research on evaluating methods for fault zone activity (without using age of over-lying strata) and its hydro-mechanical influence along fault zone (hydrothermal activity, deep-seated fluid / gas, groundwater, magma activity, etc.) will be carried out. Studies that evaluate the relationship between any of these and uplift / subsidence and erosion / sedimentation from the viewpoint of tectonics are also possible. In particular, in this recruitment, it is desirable to conduct research and development using the methods of dynamic and kinematic inverse analysis related to the formation and activity of faults and fractures.(https://www.jaea.go.jp/04/tono/) |
