JAEA Reports

Data of radon measurement in underground facilities of Mizunami Underground Research Laboratory

Mizunami Underground Research Laboratory (MIU) Project is pursued by Japan Atomic Energy Agency (JAEA) in the crystalline host rock (granite) as a part of geoscientific study of JAEA, and underground facilities of MIU are constructed down to 500m blow the ground surface. As small amount of Uranium is normally contained in granite, high concentration of radon is sometimes detected in the air of the underground facilities constructed in granitic rocks depending on their ventilation conditions. Radon concentrations in underground facilities of MIU have been measured according to the excavation progress of underground facilities or the change of ventilation system. It is recognized that the data obtained by the actual measurement of radon concentration in such underground facilities are rare and valuable. This repot summarizes the measured data from fiscal 2010 to fiscal 2020, together with the information of ventilation conditions and air temperature which affect radon concentrations in underground facilities. The variation of the equilibrium factors of radon is also examined with the actually measured data. As a result, it has been found that radon concentration in the drift is high in summer and low in winter according to the natural ventilation caused by the seasonal temperature difference between in and out of the underground facilities. Furthermore, the temporary increase in the equilibrium factor of radon in the drift at the start of ventilation is supposed to be due to the aerosol increase by the ventilation flow, such as the dust blown up.

Japan Atomic Energy Agency has been investigating groundwater chemistry to understand the influence of excavation and maintenance of underground facilities as part of the Mizunami Underground Research Laboratory (MIU) Project in Mizunami, Gifu, Japan. In this report, we compiled data of groundwater chemistry and microbiology obtained at the MIU in the fiscal year 2019. In terms of ensuring traceability of data, basic information (e.g. sampling location, sampling time, sampling method and analytical method) and methodology for quality control are described.

The Advisory Committee of International Nuclear Information System (INIS) for Japan

Under the International Atomic Energy Agency (IAEA), the International Nuclear Information System (INIS) Programme commenced in 1970 and ever since INIS has been acting as a database system available worldwide through information networks each time providing bibliographic information then full text documents of literature, technical reports, etc. on peaceful use of nuclear science and technology, thoroughly supported and maintained by INIS Secretariat in Vienna, on the other hand the inputs for INIS are provided by Member States and Organizations in their own boundaries. As for the INIS activity in Japan, while, the Japan Atomic Energy Research Institute (JAERI), then succeeded as the Japan Atomic Energy Agency (JAEA) as of today, the both have been responsible with the INIS activity in Japan as the INIS National Centre for Japan based on the request of the "former" Science and Technology Agency of the Japanese Government, an advisory committee had have a very important role for the INIS activity in Japan by enthusiastically advising the whole related to the activity from advanced and comprehensive viewpoints of expertise. This report describes about it, the Advisory Committee of International Nuclear Information System (INIS) for Japan, successfully been held 34 times from Oct. 1970 to Mar 2005. Included are the history and its records, change of the member and topics of the Advisory Committee, and the minutes.

Case study of research data policy development in JAEA

Kumazaki, Yui

no journal, , 

The Japan Atomic Energy Agency (JAEA) is preparing a research data policy that defines a policy for the management and open of research data. We conducted some surveys of the current handling and open of research data and interviewed with researchers. In the discussions so far, the following are discussed: (1) prudent judgment is necessary for open due to the characteristics of JAEA's R&D; (2) difficulty in establishing a unified policy due to the diversity of R&D fields; and (3) necessity to ensure the quality and reliability of our research data. This time, I would like to introduce the status of these surveys and studies, and consider the management of research data in organizations.
