External Hazard Lightning Lightning Protection Lightning Surge Reprocessing Plant Safety Design
August 2nd, 2015, there occurred a lot of alarms that inform the abnormal status of the important instrumentation for safety of the Rokkasho reprocessing plant (RRP). As a result of examination, it was identified that lightning was a cause of this trouble and double malfunctioned the important instrumentation for safety. On the other hand, the regulatory requirements for nuclear facilities have become restrictive since the Great East Japan Earthquake. New regulatory standard has been enforced in Novemb...

Corrosion Liquid droplet impingement Nuclear reactor Pipe wall thinning Stainless steel Wear
In this paper, to study the wear properties of the pipe materials for the nuclear power stations, a high temperature impact fretting testing was carried out. Employing two piezo actuators, impact fretting test rig can generate impact fretting under various impact loads, fretting amplit udes and frequencies. It also enables us to control water temperature, dissolved oxygen and water pressure. AISI type 304 stainless steel, which is used as a pipe material in nuclear power stations, was used as specimens. Al...

Corrosive wear Impact fretting Liquid droplet impingement erosion Pipe wall thinning Stainless steel
In order to study the wear properties of the pipe materials for the power generating plants, impact fretting wear tests of AISI304 disks against Al2O3 balls and AISI304 balls were carried out in high temperature pure water. SEM, EPMA, 3D-profilometer and nano-indenter were used for observation, analysis and measurement of wear scars. The maximum wear depth of the disk increased with an increase in water temperature and decreased with an increase in impact frequency below 80°C. However, the maximum we...
