Kaku Nenryo, (54-1), p.16 - 19, 2019/03

Japan Atomic Energy Agency (JAEA) holds the international meeting, "Fuel Safety Research Meeting" (FSRM). The purpose of this meeting is to exchange information and make discussion with domestic and foreign experts in terms of the safety of light-water reactor fuel. This report describes the outline of FSRM2018 held in Mito, Ibaraki, on October 30 and 31, 2018.

In order to evaluate adequacy of present safety criteria and safety margins in terms of advanced fuels and provide a database for future regulation on them, JAEA started an extensive research program called ALPS-II program, which has been sponsored by NRA, Japan. This program is primarily composed of tests simulating a RIA and a LOCA on the high-burnup advanced fuels irradiated in commercial PWR or BWR. Recently, the failure limits of the high-burnup advanced fuels under RIA conditions were investigated at NSRR, and post-test examinations on the fuel rods after the pulse irradiation tests are being performed. In terms of the simulated LOCA test, integral thermal shock tests and high temperature oxidation tests were carried out at RFEF, and the fracture limits, high temperature oxidation rate, etc. of the high-burnup advanced fuel cladding were investigated. This paper mainly describes some recent experimental results obtained in this program with respect to RIA and LOCA.

High-resolution photoemission study of the hybridization gap in the Kondo semiconductor CeRhAs

Shimada, Kenya*; Higashiguchi, Mitsuharu*; Arita, Masashi*; Namatame, Hirofumi*; Taniguchi, Masaki*; Fujimori, Shinichi; Saito, Yuji; Fujimori, Atsushi; Takata, Yasutaka*; Shin, S.*; et al.

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.

Direct observation of a quasiparticle band in CeIrIn$$_5$$; An Angle-resolved photoemission spectroscopy study

We have performed a high-resolution angle resolved Ce 4$$d$$-4$$f$$ resonant photoemission experiment on the heavy fermion superconductor CeIrIn$$_5$$. We have observed a quasi-particle band which has a energy disepersion of $$sim$$ 30 meV in the Ce 4$$f$$ on-resonance spectra. The result suggests that although the Ce 4$$f$$ spectra are dominated by the localized/correlated character being dominant, the small itinerant component is responsible for the superconductivity in this compound.
