• 要約等: <p>For the sustainable use of nuclear power, it is essential to implement geological disposal of radioactive wastes, especially high-level radioactive wastes. In the safety assessment of geological disposal, the repository, the surrounding host rock, and the environment up to the surface are considered as a single system, and the migration of radionuclides within the media that make up this system, i.e., the engineered barrier and the natural barrier, is assessed, and the exposure dose to humans living on the surface is calculated. In this context, geochemistry plays an important role in understanding phenomena relevant to the migration of radionuclides and their modeling. In this review, we summarize the role of geochemistry in safety assessment of geological disposal and introduce a study on the origin of dissolved organic matter and its reactivity with metal ions in deep underground water as an example of geochemical research using an underground research laboratory.</p>
