Proceedings of 2008 International High-Level Radioactive Waste Management Conference (IHLRWM 2008) (CD-ROM), p.101 - 108, 2008/09

The surface-based investigation (Phase I) in the Horonobe URL project has been conducted from March, 2001 until the end of the year 2005 as shown in Figure 1. Throughout the Phase I investigation, the concepts of geosynthesis and iterative assessment of the stepwise investigations were introduced towards characterization of the geological environment in the area including Horonobe URL site and the applicability was confirmed. The achievement of the Phase I investigation was summarized in the year 2006 and the relevant progress reports were published in March, 2007. In this paper, the concepts based on the geosynthesis methodology and its iterative application throughout stepwise investigations applied in the Horonobe URL project are discussed and summarized.

The Horonobe URL Project started in 2000. Research and development activities are planned over three phases, that will span a total duration of about 20 years: the 1st surface-based investigarion phase (6 years), the 2nd URL construction phase (8 years) and rhe 3rd operation phase (12 years). Geological, geophysical, geo-mechanical, hydrogeological, and hydro-geochemical investigations have been carried out during the surface-based investigation.
