Development of Non-Contact Type Chewing Sensor Using Photo-Reflector

Autor: Shota Nakashima, Serikawa Seiichi, Yuhki Kitazono, Shoichi Ono, Makoto Miyauchi

Publikováno v: Applied Mechanics and Materials. 103:611-615

This paper proposes a new non-contact type chewing sensor using photo-reflector. The modulated infrared rays from the infrared LED of photo-reflector irradiate the mandible. The reflected light is received by the photo detector of photo-reflector. Th

Analysis of water radiolysis in relation to stress corrosion cracking of stainless steel at high temperatures – Effect of water radiolysis on limiting current densities of anodic and cathodic reactions under irradiation

Autor: Kenkichi Ishigure, Takashi Nukii, Shoichi Ono

Publikováno v: Journal of Nuclear Materials. 350:56-65

Electrochemical corrosion potential (ECP) is an important measure for environmental factor in relation to stress corrosion cracking (SCC) of metal materials. In the case of SCC for in-core materials in nuclear reactors, radiolysis of coolant water de

Numerical Simulation of Influence of Hydrogen Peroxide Photolysis on Water Chemistry in BWR Plant

Autor: Shoichi Ono, Masafumi Domae, Mamoru Hishida

Publikováno v: Journal of Nuclear Science and Technology. 38:637-644

As a novel technique to enhance the effect of H2 addition for HWC (hydrogen water chemistry) in BWR coolant, UV light photolysis of H2O2 was proposed. The effect of the H2O2 photolysis on water radiolysis was simulated for a batch system at 288°C. I
