Environmental radiation monitoring around the Tokai Reprocessing Plant has been performed by the Nuclear Fuel Cycle Engineering Laboratories, based on "Safety Regulations for the Reprocessing Plant of Japan Atomic Energy Agency, Chapter IV - Environmental Monitoring". This annual report presents the results of the environmental monitoring and the dose estimation to the hypothetical inhabitant due to the radioactivity discharged from the plant to the atmosphere and the sea during April 2014 to March 2015. In this report, some data include the influence of the accidental release from the Fukushima Daiichi Nuclear Power Station of Tokyo Electric Power Co. in March 2011.

Small-angle neutron scattering for biology; Application of SANS to biological study

Endo, Hitoshi; Sugiyama, Masaaki*; Inoue, Rintaro*

Hamon, 22(3), p.258 - 267, 2012/08

In this text, the authors introduce two powerful techniques and one developing one for Small-Angle Neutron Scattering (SANS). The most fascinating feature of neutron as a scattering probe is its isotope effect in hydrogen. The first topic is concerning about recent progress on Contrast Variation Method: the author shows how to apply the contrast variation method to protein-mineral complex system and analyze the data. The second is concerning about deuteration-labeling: the author shows kinetics analysis in quaternary structure of homo-oligomeric protein with this technique. The final topic is concerning about the next generation analysis: an analysis method coupling SANS with neutron spin echo for dynamics of tertiary structure of protein.

Preparation of crosslinked fluoropolymer electrolyte membranes for use in fuel cells and then investigated their structural properties

Inoue, Yutaka; Kobayashi, Kazuhiro; Yamaki, Tetsuya; Asano, Masaharu; Kubota, Hitoshi*; Yoshida, Masaru

Dai-2-Kai 21-Seiki Rengo Shimpojiumu; Kagaku Gijutsu To Ningen Rombunshu, p.257 - 260, 2003/00

We prepared crosslinked fluoropolymer electrolyte membranes for use in fuel cells and then investigated their structural properties by X-ray diffraction (XRD) analysis. The radiation-induced grafting of styrene into crosslinked polytetrafluoroethylene (PTFE) films and subsequent sulfonation enabled us to obtain the electrolyte membrane with a sufficient ion exchange capacity, which exceeds that of the commercially-available film, Nafion. As the crosslinking and styrene grafting reactions proceeded, the size of the PTFE crystallites in the film became smaller, thereby decreasing the film crystallinity. Interestingly, in contrast to Nafion, the resulting sulfonated membranes were found to have high crystallinity.
