Eduardo Alonso,J. Alcoverro,F. Coste,L. Malinsky,Véronique Merrien-Soukatchoff,I. Kadiri,Thomas Nowak,Hua Shao,Thanh Son Nguyen,A.P.S. Selvadurai,A.P.S. Selvadurai,G. Armand,G. Armand,Steven R. Sobolik,M. Itamura,Charles M. Stone,Stephen W. Webb,A. Rejeb,Michel Tijani,Z. Maouche,Akira Kobayashi,Hiroshi Kurikami,Akira Ito,Y. Sugita,Masakazu Chijimatsu,Lennart Börgesson,Jan Hernelind,Jonny Rutqvist,Chin-Fu Tsang,Petri Jussila +29 more
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
Thermological Study of Drilling Bone Tissue with a High-speed Drill
Soichiro Kondo,Yoshikazu Okada,Hiroshi Iseki,Tomokatsu Hori,Kintomo Takakura,Akira Kobayashi,Hirokazu Nagata +6 more
TL;DR: Intentional intermittent drilling with irrigation reduces temperature elevation and its expansion and these procedures are necessary for safe drilling, especially with a diamond burr.
Journal ArticleDOI
Characterising and modelling the excavation damaged zone in crystalline rock in the context of radioactive waste disposal
John A. Hudson,Ann Bäckström,Jonny Rutqvist,Lanru Jing,T. Backers,Masakazu Chijimatsu,Rolf Christiansson,Feng Xuelei,Akira Kobayashi,Tomofumi Koyama,Tomofumi Koyama,H-S. Lee,Ivars Neretnieks,Peng-Zhi Pan,Mikael Rinne,Baotang Shen +15 more
TL;DR: In this paper, the authors describe current knowledge about the nature of and potential for thermo-hydro-mechanical-chemical modelling of the excavation damaged zone (EDZ) around the excavations for an underground radioactive waste repository.
Journal ArticleDOI
A multiple-code simulation study of the long-term EDZ evolution of geological nuclear waste repositories
Jonny Rutqvist,Ann Bäckström,Masakazu Chijimatsu,Xia-Ting Feng,Peng-Zhi Pan,John A. Hudson,Lanru Jing,Akira Kobayashi,Tomofumi Koyama,Hee-Suk Lee,Xiao-Hua Huang,Mikael Rinne,Baotang Shen +12 more
TL;DR: In this paper, a simulation study shows how widely different model approaches can be adapted to model the evolution of the excavation disturbed zone (EDZ) around a heated nuclear waste emplacement drift in fractured rock.
Journal ArticleDOI
Modeling of damage, permeability changes and pressure responses during excavation of the TSX tunnel in granitic rock at URL, Canada
Jonny Rutqvist,Lennart Börgesson,Masakazu Chijimatsu,Jan Hernelind,Lanru Jing,Akira Kobayashi,Son Nguyen +6 more
TL;DR: In this paper, the authors present numerical modeling of excavation-induced damage, permeability changes, and fluid-pressure responses during excavation of a test tunnel associated with the tunnel sealing experiment (TSX) at the Underground Research Laboratory (URL) in Canada.
