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 2019 to March 2020. In this report, some data include the influence of the accidental release from the Fukushima Daiichi Nuclear Power Station of Tokyo Electric Power Co., Inc. (the trade name was changed to Tokyo Electric Power Company Holdings, Inc. on April 1, 2016) in March 2011. Appendices present comprehensive information, such as monitoring programs, monitoring methods, monitoring results and their trends, meteorological data and discharged radioactive wastes. In addition, the data which were influenced by the accidental release and exceeded the normal range of fluctuation in the monitoring, were evaluated.

Electronic structure and magnetism of CaMn$$_{1-x}$$Ru$$_{x}$$O$$_{3}$$ thin films

We have studied the electronic and magnetic properties of epitaxially grown CaMn$$_{1-x}$$Ru$$_{x}$$O$$_{3}$$ (x = 1.0, 0.5) thin films by X-ray magnetic circular dichroism (XMCD) and hard X-ray photoemission spectroscopy (HXPES). The XMCD studies indicated that the spin moments of Mn and Ru are aligned in the opposite directions. The HXPES spectra indicated the Ru 4d states at around the Fermi edge (E$$_{F}$$) and the Mn 3d states below E$$_{F}$$. From these results, we propose that the localized Mn 3d t$$_{2g}$$ states and the itinerant Ru 4d t$$_{2g}$$ band are antiferromagnetically coupled and give rise to ferromagnetism, in analogy with the mechanism proposed for the double perovskite oxides such as Sr$$_{2}$$FeMoO$$_{6}$$.

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.

To reasonable abolition measures of the nuclear installation, it is important to select the best dismantlement scenario after some dismantlement scenarios are assumed beforehand and the control parameters of an artificial number and the amount etc. of waste are evaluated. Therefore, JAEA and Fukui University were jointly advancing the examination of the management parameter evaluation technique to use it for a turbine system condenser in the future and the dismantlement plan of equipment etc. the nuclear reactor peripheral, and the taking settling of the dismantlement results data of "Fugen" to have started the demolition work since fiscal year 2008 was done as input information to construct the valuation modeling.
