To secure the seismic safety of the thin-walled mechanical components and piping under a severe design earthquake level, employing a three-dimensional (3D) seismic isolation system has been planned in a sodium-cooled fast reactor. The development results of the 3D isolation system have been reported in previous papers so far. Its update is reported in Part 7 to Part 9. Part 7 describes the overview of the development, the test plan of the isolation system in the assembled state of each element, and the performance of individual isolation elements. In part 8, the performance of the isolation device that each element was assembled into was investigated through loading tests. Part 9 reports analytical studies by an analysis model validated based on the insight of the test results.

Times Cited Count:2 Percentile:9.59(Physics, Condensed Matter)To examine the detailed structure of low-energy magnetic excitations in a high-transition-temperature superconducting cuprate with heavily hole-doping, we performed inelastic neutron scattering experiments on LaSrCuO. We observed clear dispersion relations of the previously reported incommensurate (IC) magnetic correlations at = (0.5 , 0.5)/(0.5, 0.5 ). In addition, we show the emergence of continuum magnetic excitations with a ring shape centered at point in a constant energy spectrum at = 50 K. The radius of the ring ( = 0.109) is smaller than the incommensurability ( = 0.118). This suggests that the origin of the ring-like excitations is different from that of the IC magnetic correlations, and the low-energy magnetic excitations of the LaSrCuO system are inherently composed of these two kinds of excitations.
