Journal of Nuclear Materials > 2015 > 466 > C > 502-508

Electrorefining of irradiated metallic fuels was successfully demonstrated: Actinides (U, Pu, Np, Am and Cm) in the fuels were dissolved in LiCl–KCl melts with high dissolution ratios, while U was selectively deposited on a solid cathode and the simultaneous recovery of actinides in a liquid Cd cathode was confirmed. The behavior of actinides, the fuel matrix stabilizer Zr and fission products such...

Separation of actinides from irradiated An–Zr based fuel by electrorefining on solid aluminium cathodes in molten LiCl–KCl

P. Souček, T. Murakami, B. Claux, R. Meier, more

Journal of Nuclear Materials > 2015 > 459 > C > 114-121

An electrorefining process for metallic spent nuclear fuel treatment is being investigated in ITU. Solid aluminium cathodes are used for homogeneous recovery of all actinides within the process carried out in molten LiCl–KCl eutectic salt at a temperature of 500°C. As the selectivity, efficiency and performance of solid Al has been already shown using un-irradiated An–Zr alloy based test fuels, the...

K. Fujikawa, K. Migita, Y. Shigemitsu, M. Umeda, more

Clinical & Experimental Immunology > 178 > 2 > 224 - 228

Inflammatory myopathy with abundant macrophages (IMAM) has recently been proposed as a new clinical condition. Although IMAM shares certain similarities with other inflammatory myopathies, the mechanisms responsible for this condition remain unknown. Patients with familial Mediterranean fever (FMF) and tumour necrosis factor receptor‐associated periodic syndrome (TRAPS) also often develop myalgia...

IEEE PES Innovative Smart Grid Technologies > 1 - 5

2012 IEEE Innovative Smart Grid Technologies - Asia (ISGT Asia)

Photovoltaic (PV) system is installed in power system as one of the countermeasures for problems of the global warming. The output fluctuations due to the climate condition make an impact to the power system. As one of solutions for this problem, installation of the battery energy storage system (BESS) has been proposed. However, since the BESS is still expensive, it is favorable to reduce the capacity...

Development of remote welding techniques for in-pile IASCC capsules and evaluation of material integrity on capsules for long irradiation period

A. Shibata, J. Nakano, M. Ohmi, K. Kawamata, more

Journal of Nuclear Materials > 2012 > 422 > 1-3 > 14-19

To simulate irradiation assisted stress corrosion cracking (IASCC) behavior by in-pile experiments, it is necessary to irradiate specimens up to a neutron fluence that is higher than the IASCC threshold fluence. Pre-irradiated specimens must be relocated from pre-irradiation capsules to in-pile capsules. Hence, a remote welding machine has been developed. And the integrity of capsule housing for a...

Theoretical study on segregation of Cu, Mo and W impurities and stability of impurity–vacancy pairs in bcc Fe

T. Tsuru, Y. Abe, C. Suzuki, T. Nakazawa, more

Journal of Nuclear Materials > 2011 > 417 > 1-3 > 1054-1057

Reduced activation ferritic steel is one of the leading structural material candidates for a nuclear fusion reactor, in which tungsten is introduced in order to improve the radiation resistance. Since the solute impurities have an effect on the embrittlement through segregation under irradiation, the stability of impurity elements should be elaborated. In the present study the segregation characteristics...
