The underground research shafts and drifts have been constructed in Horonobe by JAEA. The observational construction program to reflect the various data obtained by the shaft excavation for designing and construction was setted on and is being presently applied. The support design was carried out by numerical analysis considering the excavating liberaring power according to the excavation progress. But, it was clear that measurement data of lining stress in G.L.-121m included the influence of extra lining thickness and excavation of drifts in G.L.-140m. We report on the outline of the observational construction program and the result of analyzing the measurement data of the lining stress.

JAEA is carrying out phased investigation in Horonobe. This investigation, named as "Horonobe Underground Research Laboratory Project" (Horonobe URL Project) targeting sedimentary formations, is intended to confirm the reliability of technologies on geological disposal of High-Level Radioactive Waste (HLW) by applying them into in-situ geological environment. On the "Development of engineering techniques for use in the deep underground environment" in Phase 1 of the Horonobe URL project, based on the various type of data acquired on investigations from the surface, basic design of underground facilities in advance was carried out. This report summarizes the measurement plan during construction of the underground facility based on the design in advance and the observational construction program for feedback measurements data into design and construction on subsequent steps. This report also describes about design and construction management program for contractor of underground facilities. The measurement plan described in this document is applied to measurements in the underground facilities for validation of the geological environmental model. Then, it will be verified the validity by application into actual construction and will be systematized with modification when necessary.

JAEA is developing two off-site underground research laboratory projects: one in sedimentary rock (Horonobe, Hokkaido) and the other in crystalline rock (Mizunami, Gifu) in Japan. Horonobe's URL project consists of three major phases: (1) surface-based investigation (Phase I); (2) construction (Phase II); and, (3) operation (Phase III). At present, Phase II has been started. In parallel, predictions of potential changes in the geological environment prevailing around the URL are in progress. This paper mainly gives an overview of the technical aspects covered by Phase I as well as presents the design for the URL. Future plans after Phase II are briefly introduced as well.

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.

We held Horonobe technical review meeting 4 times a year. The first meeting is for the plan of Horonobe underground research laboratory and others. The secound meeting is for geology of Horonobe area and modeling study and data acquisition for safety assessment methodology and others. The third meeting is for ventilation network analyses on URL plan. The fourth meeting is for the remote monitoring system using ACROSS. This report is records of these meetings.

Japan Nuclear Cycle Development Institute (JNC) is pursuing two underground research laboratory (URL) projects to conduct a systematic research on geological disposal of high level radioactive wastes. The Tono Geoscience Center (TGC) has been carrying out research and development in crystalline rocks at Mizunami in central Japan and the Horonobe Underground Research Center in sedimentary rocks at Horonobe in northern Japan. Both projects are nearing termination of the first phase of surface-based investigation and is about to move on to the next phase of actually constructing the facilities underground. To mark this transition of phases, an international conference is organized to promote domestic and international recognition for the significance of constructing the URLs by disseminating research findings to a broad range of researchers and specialists from within and outside Japan as well as to the local community.

JNC(Japan Nuclear Cycle development institute) has been conducting the project called "Horonobe URL project" in Horonobe-cho, Hokkkaido, Japan. The aim of the project is to establish the scientific and technical basis for geological disposal on sedimentary rock. In the project, a underground facility with 500m depth will be constructed. This report is summarized the results on support design of the planned underground facility based on the data obtained by the several borehole investigations from ground surface. Owing to rational support design, the detailed compartment of the input parameters for the stability analysis in surrounding rock at position of underground facility were made based on the results of borehole investigation in HDB-1, HDB-3, which were drilled near the position. Moreover, the idea of double support system was adopted in this study to minimize the support in underground facility.

The Horonobe Underground Research Laboratory (URL) Project is being pursued by the Japan Atomic Energy Agency (JAEA) to enhance the reliability of relevant disposal technologies through investigations of the deep geological environment within the host sedimentary formations at Horonobe, northern Hokkaido. The project consists of two major research areas, "Geoscientific Research" and "R&D on Geological Disposal", and proceeds in three overlapping phases, "Phase I: Surface-based investigation", "Phase II: Construction" and "Phase III: Operation", over a period of 20 years. The present report summarises the results of the Phase I geoscientific research carried out from March 2001 to March 2005. Integration of work from different disciplines into a "geosynthesis" ensures that the Phase I goals have been successfully achieved and identifies key issues that need to be addressed in the Phase II/III investigations.
