Preventive Effect of Shot Peening on Stress Corrosion Cracking
Autor: Tetsuya Ishikawa, Toshihiko Yoshimura, Enomoto Kunio, Ren Morinaka, Saito Hideyo, Shinobu Okido
Publikováno v: Journal of the Society of Materials Science, Japan. 51:193-198
The effect of shot peening (SP) on stress corrosion cracking (SCC) prevention was evaluated from the viewpoints of crack initiation and propagation. It was found that the residual stress in a Type-304 stainless-steel specimen is changed-from tensile

Application of Water Jet Peening on Pre-Cracked Nickel Based Alloy and Stainless Steel
Autor: Akihiro Kanno, Noboru Saito, Kunihiro Hasegawa, Ren Morinaka, Fujio Yoshikubo
Publikováno v: Volume 1: Codes and Standards.
Water Jet Peening (WJP) has been widely applied to Japanese nuclear power plants since 1999 in order to mitigate stress corrosion cracking (SCC) generation on SCC susceptible material used their reactors as an approved mechanical mitigation technique

Prediction of Residual Stress Improvement by Water Jet Peening Using Cavitating Jet Simulation With Bubble Flow Model
Autor: Ren Morinaka, Yoshiaki Tamura, Masashi Fukaya, Noboru Saitou, Yoichiro Matsumoto, Hisamitsu Hatou
Publikováno v: ASME 2010 3rd Joint US-European Fluids Engineering Summer Meeting: Volume 1, Symposia – Parts A, B, and C.
We developed the new method for predicting a region of compressive residual stress on the weld surface after water jet peeing (WJP), which is a preventive maintenance technology for nuclear power plants. A cavitating jet is impinged on the weld surfa

Detection of Radiation Damage in Low Alloy Steel Using a Squid Sensor
Autor: Atsunori Yamaguchi, Sadato Shimizu, Noriyoshi Maeda, Ren Morinaka, Otaka Masahiro
The magnetic properties of A533B low alloy steel irradiated up to 3 {times} 10{sup 23} n/m{sup 2} in a nuclear reactor were measured using a SQUID sensor. The SQUID sensor used in the test is the type with a first-order axial gradiometer. Test specim
