The Japan Atomic Energy Agency has been involved in ongoing research in the Horonobe area for the purposes of geoscientific research, and research and development (R&D) on technologies to be used for the geological disposal of high-level radioactive waste. The chemistry of groundwater and dissolved gas from deep boreholes has been obtained since H13 fiscal year for R&D on technologies related to geological characterization. Horonobe Research Institute for the Subsurface Environment (H-RISE) has investigated a resources development on promoting effective use of coal bed buried in Hokkaido including the Horonobe area using microbial communities. The data of dissolved gas from the Horonobe groundwater have also been obtained along with the microbiological research by H-RISE. Central Research Institute of Electric Power Industry (CRIEPI) has conducted R&D on technology of groundwater geochronology which is one of technologies to be used for the geological disposal, and noble gas data from the Horonobe groundwater have been obtained by CRIEPI. This report shows a data set which comprises gas data obtained from the Horonobe underground research project during the period from H13 fiscal year to H27 fiscal year.

An outdoor-use laser system to improve the performances of existing tunnel inspection techniques is studied. One of the typical concepts is that the blow by hammer in routine hammering test is replaced by the laser pulse irradiation. This new laser system is required to provide high average output power (5 J, 50 Hz, 15 ns) with a compact geometry enough to mount on the inspection vehicle (4.2 m 0.8 m). Dramatic speed-up of the inspection is expected by the combination of this new laser system and a laser scanning frequency measurement system.

One of the typical concepts is that the blow by hammer in routine test is replaced by the laser pulse irradiation. This new laser system is required to provide high average output power (5 J, 50 Hz, 15 ns) with a small-scale geometry enough to mount on the inspection vehicle (4.2 m 0.8 m). In this presentation, we will report a potential to demonstrate 5 J output.

A lot of infrastructure constructions were built in the 1940s and 1950s in Japan and these decrepitude are seriously concerned that leading to a serious accident. Recently, a novel inspection method using laser systems which consists of impact laser and detection laser, is energetically developing because of its significant advantages. A role of the impact laser is to induce the vibration on concrete walls by the high energy laser pulse behaving like hammering. Then, the detection laser set in laser differential interferometer that which detects the vibration of the concrete surface. For putting into actual utilization, the inspection speed which is about several ten meters per night should be improved for the exceedingly-long train-tunnels. The inspection speed of impact laser and detection systems is required a high-frequency measurement. In this study, we developed a new prototype inspection system to realize high speed inspection for defects inside concrete.
