• A Coupled Modeling Simulator for Near-Field Processes in Cement Engineered Barrier Systems for Radioactive Waste Disposal

  Steven J. Benbow, Daisuke Kawama, Hiroyasu Takase, Hiroyuki Shimizu, Chie Oda, Fumio Hirano, Yusuke Takayama, Morihiro Mihara, Akira Honda

  Details are presented of the development of a coupled modeling simulator for assessing the evolution in the near-field of a geological repository for radioactive waste disposal where concrete is used as a backfill. The simulator uses OpenMI, a standard for exchanging data between simulation software programs at run-time, to form a coupled chemical-mechanical-hydrogeological model of the system. The approach combines a tunnel scale stress analysis finite element model, a discrete element model for accurately modeling the patterns of emerging cracks in the concrete, and a finite element and finite volume model of the chemical processes and alteration in the porous matrix and cracks in the concrete, to produce a fully coupled model of the system. Combining existing detailed simulation software in this way with OpenMI has the benefit of not relying on simplifications that might be necessary to combine all of the modeled processes in a single piece of software.

• A study on applicability of elasto-plastic constitutive model to mechanical behavior of buffer material in salt water conditions

  TAKAYAMA Yusuke, KIKUCHI Hirohito

    In this study, an applicability of the modified Cam clay model to the buffer material under salt water conditions was examined. Consolidated-undrained triaxial test was conducted using NaCl solution and artificial seawater. Based on the consolidated-undrained triaxial compression test results and the existing consolidation test results, the difference in the mechanical behavior of the buffer material under distilled water and saltwater condition was clarified. In particular, there was a difference in the unloading behavior in the consolidation test. Through reproducibility analysis of these experimental data, it was confirmed that the mechanical behavior of the buffer material can be roughly reproduced by setting the swelling index according to the salt concentration.

• Long-term mechanical analysis code considering chemical alteration for a TRU waste geological repositor

  MIHARA Morihiro, HIRANO Fumio, TAKAYAMA Yusuke, KYOKAWA Hiroyuki, OHNO Shintaro

    A computer program MACBECE has been developed to provide rigorous calculations of the long-term mechanical behavior of a TRU waste geological repository. Consideration is given to the expected chemical alteration of repository components, including cementitious materials and bentonite, and the mechanical interactions between repository and host rock. The long-term mechanical behavior of a TRU waste repository was evaluated in a deep soft rock site, where creep deformation is likely to occur from the initial construction phase to 10⁵ years after repository closure. It was found that the stress didn't fall into a singularity of yield surface of the EC model applied to the mechanical behavior model of bentonite. The calculated displacement of the inner diameter of the repository, considering mechanical interaction between repository and host rock, was about half that of a result in 2nd progress report on R&D for TRU waste disposal in Japan.

• Numerical study on seawater intrusion in non-uniform aquifer

  SAITO MASAHIKO, TAKAYAMA YUSUKE, NAKAGAWA KEI

  Illegal dumping at the mountainside is one of serious problem in Japan. However, the conventional approaches to the groundwater pollution problem mainly focus on the urban area or flat land. In this study, it was investigated that the change of water content and solute transport caused by rainfall infiltration in the model slope by experiment and numerical analysis. The results show that the change of pore pressure was reproduced well by numerical analysis, and peak value of the concentration at the points near the source was also reproduced well. But, the calculated value of the concentration at the point far from the source was different from measured value.

• NUMERICAL STUDY ON SEAWATER INTRUSION IN NON-UNIFORM AQUIFER

  SAITO Masahiko, TAKAYAMA Yusuke, NAKAGAWA Kei

  Knowledge of seawater intrusion to aquifer is very important for the efficient use of groundwater in coastal area. Conventional numerical simulation for seawater intrusion was mainly performed in uniform porous media. However it is known that hydraulic conductivity varies spatially. The objective of this paper is to investigate a seawater intrusion behavior in non-uniform porous media by numerical simulation using the spatial distribution model for hydraulic conductivity. The results show that the length of seawater intrusion is affected by the shape of permeability distribution. When the aquifer has laminar structure of permeability, the change of seawater intrusion length is smaller than the general aquifer.
