Japan Atomic Energy Agency (JAEA) has two facilities of accelerator mass spectrometry, JAEA-AMS-TONO and JAEA-AMS-MUTSU at Tono Geoscience Center and Aomori Research and Development Center, respectively. In this report, characteristics of each facility and results of standard samples in the inner-comparison test of carbon isotope measurement will be described. Both facilities have been used for research by not only JAEA's staff but also researchers who belong to universities and other institutes on the shared use program of JAEA facilities. Recently, researchers trend to use both facilities with the expansion of demand for the carbon isotope measurement by using the accelerator mass spectrometer (AMS). However, each facility has a spectrometer made by a different manufacturer and equipped with different mechanical components. There is a difference in each ability to the carbon isotope measurement such as background level. This is, for example, due to different ion injection system adapted at each spectrometer. Further, each facility uses a different analytical method adjusted to each main research field. When a researcher uses both facilities, the researcher understands more about the characteristics and need to make a suitable choice of a facility for samples and the analytical method. The report presents a detailed information of characteristics of the spectrometer, sample preparation method and analytical method, and of ability of the measurement based on the inner-comparison test.

Nuclear Facilities Management Section implemented the operation, maintenance and decommissioning of the first nuclear ship "MUTSU" and the operation and maintenance of the liquid waste facility and the solid waste facility where a small amount of nuclear fuel is used. The Nuclear Facilities Management Section became the Nuclear Facilities and General Facilities Management Section by organization unification in FY 2016. This is the report on the operations of the Nuclear Facilities Management Section for FY 2014 and FY 2015.

Based on repeated DPRK's nuclear tests, the Japanese government contributed funds for the noble gas measurement project in February 2017 for the purpose of strengthening CTBTO's detection capability for nuclear tests. The CTBTO decided to conduct measurements in Hokkaido and Tohoku regions of Japan for the time being, and to enhance JAEA with experiences and performance of measurements in Japan as the responsible organization. In response to this, the JAEA has installed two mobile noble gas measurement systems at Horonobe, Hokkaido and JAEA Ohminato site in Mutsu, Aomori, and been carrying out the joint measurement project with the CTBTO. The current status of this project will be presented.

In early 2018, two mobile noble gas measurement systems were deployed and have started measurement at Horonobe and Mutsu in Japan. Together with a third mobile system that will be deployed at Fukuoka, Japan, in spring 2019, and the operating IMS noble gas system at station RN38, Takasaki, Japan, this creates a high density configuration of noble gas measurement systems. The objective of this configuration is to generate a database of detections which will be used to develop and test methods for better understanding the contributions of known sources from across Eurasia. Contributions from these sources are frequently observed at IMS station RN38. The high density configuration will provide a framework to test and optimize source location algorithms and to better understand level C episodes, specifically at JPX38. The three mobile noble gas measurement systems used in this experiment and their operation are externally funded. The planned duration of this experiment is two years.
