Based on the regulations (the safety regulation of Tokai Reprocessing Plant, the safety regulation of nuclear fuel material usage facilities, the radiation safety rule, the regulation about prevention from radiation hazards due to radioisotopes, which are related with the nuclear regulatory acts, the local agreement concerning with safety and environment conservation around nuclear facilities, the water pollution control law, and by law of Ibaraki Prefecture), the effluent control of liquid waste discharged from the Nuclear Fuel Cycle Engineering Laboratories of Japan Atomic Energy Agency has been performed. This report describes the effluent control results of the liquid waste in the fiscal year 2020. In this period, the concentrations and the quantities of the radioactivity in liquid waste discharged from the reprocessing plant, the plutonium fuel fabrication facilities, and the other nuclear fuel material usage facilities were much lower than the limits authorized by the above regulations.

Structural studies of lanthanide nitrate-${it N,N'}$-dimethyl-${it N,N'}$-diphenylpyridine-2,6-dicarboxyamide complexes

Fujiwara, Asako; Nakano, Yoshiharu*; Yaita, Tsuyoshi; Okuno, Kenji*

Journal of Alloys and Compounds, 456(1-2), p.429 - 435, 2008/05

 Times Cited Count:16 Percentile:66.16(Chemistry, Physical)

The tridentate ligand ${it N,N'}$-dimethyl-${it N,N'}$-diphenylpyridine-2,6-dicarboxyamide (DMDPhPDA) and the corresponding lanthanum complex [La(NO$$_{3}$$)$$_{3}$$(DMDPhPDA)$$_{2}$$] have been prepared and structurally characterised. In the lanthanum complex, two DMDPhPDA molecules coordinated to La(III) in a tridentate fashion and to three nitrate ions in a bidentate fashion make the lanthanum atom 12-coordinate. The stability constants determined by spectrophotometric titration suggest that [Ln(DMDPhPDA)$$_{2}$$]$$^{3+}$$ is the primary product in nitrate media and [Ln(DMDPhPDA)$$_{3}$$]$$^{3+}$$ is difficult to form. However, [Ln(DMDPhPDA)$$_{2}$$]$$^{3+}$$ could not be distinguished in $$^{13}$$C NMR spectra. The $$^{13}$$C NMR titration results imply that a fast ligand exchange process takes place.

For accurate prediction of neutronic characteristics for accelerator-driven system (ADS), an experimental program to measure nuclear data on ADS using the Fixed Field Alternating Gradient (FFAG) accelerator at Kyoto University has been launched. As a part of this program, energy spectra of spallation neutron from 100-MeV proton-induced reactions on Fe, Pb, and Bi are plan to be measured. In this report, the results of the measurement on Fe target will be presented.

Toward the realization of Accelerator-Driven System (ADS), we have been measuring the nuclear data for ADS using Kyoto University FFAG accelerator. In this presentation, we report the outline and the results of the energy spectrum measurement of neutrons produced by 107 MeV proton-induced reactions on lead and bismuth, which are the most important nuclides in ADS.
