The Horonobe Underground Research Laboratory (URL) Project has being pursued by the Japan Atomic Energy Agency (JAEA) to enhance the reliability of relevant investigations of the deep geological environment within the host sedimentary formations at Horonobe, northern Hokkaido. Horonobe URL will be excavated three shafts (Ventilation shaft, East shaft and West shaft) connected by three drifts (G.L -140m, G.L -250m and G.L -350m) at the time of completion. In the construction area, the sedimentary rock has spread. And the construction position is located in the stratum boundary of Koetoi formation and the Wakkanai formation. According to the investigation from the ground, existence of the fault with springwater and of the methane separated from groundwater was confirmed. From the viewpoint of the security under construction and the control of the amount of springwater from the URL, pre-grouting was carried out. This report summarizes the construction data of the pre-grouting acquired at the Ventilation Shaft.

A Case study of economic incentives and local citizens' attitudes towards hosting a nuclear power plant in Japan; Impacts of the Fukushima accident

Kato, Takaaki*; Takahara, Shogo; Nishikawa, Masashi*; Homma, Toshimitsu

This case study of the areas that host Kashiwazaki Kariwa NPP compares local citizens' attitude towards the benefits and the drawbacks of hosting the NPP. In December 2011, our survey respondents became more negative about hosting the NPP after the Fukushima accident in March 2011 compared to the survey in January 2010. Another comparison between the November 2005 and the December 2011 surveys provided a different look. The magnitude of the negative shift in Kariwa Village, which saw a large expansion of social welfare programs, was modest in the sense that its 2011 results were similar to its 2005 results. Local tax revenues, subsidies from the national government and the donation from a utility contributed to this budget expansion in Kariwa. The negative shifts from 2005 to 2011 were clear in the other two municipalities which did not see such a large expansion of economic benefits during this period.

Role of technical reports as a means of scientific information distribution in the field of nuclear science and technology

Ishikawa, Masashi

JAEA-Review 2013-013, 51 Pages, 2013/06

JAEA-Review-2013-013.pdf:4.73MB

Japan Atomic Energy Agency has provided the twenty-thousand technical reports on the internet to publish results of research and development activities in detail. In technical reports, detailed results, experimental data, findings etc. are recorded. Technical report system is effective for communication among scientists and engineers for research development in big science like nuclear research. The number of download of technical reports is over 4.7 million in a year. Recently, scientist and engineers engaged in research and development projects are inclined to submit papers to journals which have high impact factor. But technical reports are more useful for carrying research results of big projects than journal articles. It is also useful for knowledge management to transfer results and achievements to the following generation. To improve the technical report system to meet the needs of scientists and engineers and assisting the knowledge management is proposed.

Survey on usage of electronic journals in Japan Atomic Energy Agency

Fukazawa, Takeyasu; Nakajima, Hidemitsu; Ishikawa, Masashi

Joho No Kagaku to Gijutsu, 58(6), p.301 - 305, 2008/06

Japan Atomic Energy Agency performed the survey on usage of electronic journals using "Science Direct" provided by Elsevier Science, 2006. Although JAEA researchers are interested in 1,028 titles among physics, chemistry, engineer, medicine, social sciences etc., it is found the 80% of total downloads was occupied by only 102 journal titles. To satisfy researcher's needs for electronic journals effectively, identification the core journals by librarians based on user's needs is rational way in cost. By shifting from print to electronic journals, the number of users increased by 30% and the number of papers read by researchers increased by 7 times. It is also found that many of researchers do not use SD useful functions such as searching, linking to other bibliographic records, and alerting new information of electronic journals.

Absorbed doses from main charged particle beams and charged-particle fragments have been measured with high accuracy for particle therapy but there are few reports for doses from neutron components produced as fragments. This study describes measurements on neutron dose produced by carbon beam, microdosimetric distributions of secondary neutrons produced by 290 MeV/nucleon carbon beams have been measured by using a tissue equivalent proportional counter (TEPC) at the Heavy Ion Medical Accelerator in Chiba (HIMAC) at the National Institute of Radiological Sciences (NIRS). The ratios of neutrons to charged particle fragments dominated to be 11 to 89 % in the absorbed doses at the side and below the faces of the acrylic phantom (300 mm height $$times$$ 300 mm width $$times$$ 253 mm thickness).

The Japan Atomic Energy Research Institute (JAERI) Library had contributed 312 papers through the library activities in half-century. We made the bibliography of these papers as well as categorized them into "general", "library functions", "management and promotion of research results" and "international exchange of information" and explained them under the four categories. A subject index, an author index of these papers and chronology of JAERI library activities were also compiled for reference.

High-resolution photoemission study of the hybridization gap in the Kondo semiconductor CeRhAs

Journal of Magnetism and Magnetic Materials, 310(2, Part1), p.e57 - e58, 2007/03

We have examined the electronic states of the Kondo semiconductor CeRhAs and the semimetal CeRhSb by means of high-resolution photoemission spectroscopy using tunable photon energies from 40 up to 5948 eV. On the basis of the photon-energy dependence ofthe photoionization cross-section, we have elucidated the p-d-f hybridized states in these compounds.
