Towed Marine Dipole Source for Shear Wave Generation
Autor: Hiroaki Ozasa, M. Tagami, K. Tanaka, Nagai Yuki, A. Tsuda, Hitoshi Mikada, Junichi Takekawa, F. Sato, Hiroaki Hatanaka
Publikováno v: Scopus-Elsevier
In this paper, we focused on the generation of the shear wave using a dipole source in water. We first made a scaled model of a deep-tow seismic survey using solid material with a set of reflectors and an overlain water layer and conducted an explora

Ultrasonic Creep Damage Detection by Frequency Analysis for Boiler Piping
Autor: Hirokatsu Nakagawa, Nobukazu Ido, Ryota Uemichi, Takuya Ito, Hiroaki Hatanaka, Minoru Tagami
Publikováno v: Journal of Pressure Vessel Technology. 129:713-718
Boiler piping of fossil-fuel combustion power generation plants are exposed to high-temperature and high-pressure environments, and failure of high-energy piping due to creep damage has been a concern. Therefore, a precise creep damage assessment met

Application of Ultrasonic Technique for Precipitate Detection and Viscosity Measurement of Molten Glass at Elevated Temperature
Autor: Tadashi Maruyama, Arisa Yanagihara, Hiroaki Hatanaka, Midori Uchiyama, Hajime Koikegami
Publikováno v: Volume 4: Radiation Protection and Nuclear Technology Applications; Fuel Cycle, Radioactive Waste Management and Decommissioning; Computational Fluid Dynamics (CFD) and Coupled Codes; Reactor Physics and Transport Theory.
This paper describes the results of ultrasonic examination of molten glass in the glass melter for the vitrification process of high-level radioactive liquid waste (HLW). The propagation and the attenuation of ultrasound in the molten glass were meas

Ultrasonic Examination of Noble Metal Precipitate Detection in Glass Melter
Autor: Arisa Yanagihara, Tadashi Maruyama, Hiroki Kawai, Hajime Koikegami, Hiroaki Hatanaka, Shigeyoshi Yasunaga, Toshiaki Kakihara
Publikováno v: Volume 5: Fuel Cycle, Radioactive Waste Management and Decommissioning; Reactor Physics and Transport Theory; Nuclear Education, Public Acceptance and Related Issues; Instrumentation and Controls; Fusion Engineering.
This paper describes the results of ultrasonic examination of the build-up of noble metal precipitates in the glass melter using a wave guide rod. The glass melter is used for the vitrification process of high-level radioactive liquid waste (HLLW). A
