Inadvertent withdrawal of a control rod cluster was observed during lifting of the upper core structure on the 15th outage of Ikata Unit3. The source of magnetite sludge, which is one of the causes of this event, was presumed to be the drive shaft, but there is little knowledge about the corrosion characteristics of the drive shaft material SUS410 in the PWR primary water. Therefore, we investigated the corrosion characteristics of SUS410 in simulated PWR primary water circumstance at the plant start-up sta...

Ikata unit 3 had been shutdown for more than 5 years to have measures to meet new regulatory requirement for restart. However Ikata unit 3 restarted the reactor in August 2016 and then resumed power generation. It was a restart after long shutdown unlike any Ikata NPP had ever experienced before. Ikata NPP had measures such as optimization of equipment layup practices during shutdown and chemistry control during restart to prevent introduced impurities and generated iron rust during shutdown from adverse...
