TL;DR: The FEBEX (Full-scale Engineered Barriers Experiment in Crystalline Host Rock) test was installed at the Grimsel Test Site underground laboratory (Switzerland) and is a near-to-real scale simulation of the Spanish reference concept of deep geological storage in crystalline host rock.
Journal ArticleDOI
Approaches to modeling coupled thermal, hydrological, and chemical processes in the drift scale heater test at Yucca Mountain
Eric Sonnenthal,Akira Ito,Nicolas Spycher,Mikazu Yui,John A. Apps,Y. Sugita,Mark E. Conrad,Susumu Kawakami +7 more
TL;DR: In this article, a large-scale underground thermal test (Drift Scale Test-DST) in fractured volcanic tuff resulted in changes to water and gas chemistry as well as mineral precipitation and dissolution in fractures.
Book ChapterDOI
THM Simulation of the Full-Scale In-Situ Engineered Barrier System Experiment in Grimsel Test Site in Switzerland
TL;DR: In this paper, the simulation of the thermal, hydraulic and mechanical behaviour in the buffer during heating phase is required, e.g. the evolutions and the distributions of stress, relative humidity and temperature at specified points in bentonite buffer material.
Book ChapterDOI
A Research Program for Numerical Experiments on the Coupled Thermo-Hydro-Mechanical and Chemical Processes in the Near-Field of a High-Level Radioactive Waste Repository
TL;DR: In this paper, the authors present the current status and future activities on the research for numerical experiments on the coupled T-H-M-C processes in order to predict the near-field long-term evolution.
Book ChapterDOI
Prototype Code Development for Numerical Experiments on the Coupled Thermo-Hydro-Mechanical and Chemical Processes in the Near-Field of a High-Level Radioactive Waste Repository
Atsushi Neyama,Akira Ito,Masakazu Chijimatsu,Yoshinao Ishihara,Tomoyuki Hishiya,Mikazu Yui,Y. Sugita,Susumu Kawakami +7 more
TL;DR: Using this coupling system “COUPLYS”, the prototype code for the coupled T-H-M-C processes has been developed and the efficiency and quality of existing individual process codes are improved.
