概要
Due to main condenser tube damage in May, 2011, seawater flowed into the reactor and other facilities of Hamaoka NPS Unit 5. The pitting corrosion was observed in the SUS weld metal cladding layer, welded to the inner face of the RPV base metal. In terms of the availability of RPV’s required functions, RPV would be capable of continuous use based on component health assessment in December, 2015. However, development of non-destructive inspection methods to SUS weld metal cladding was needed to conduct the inspection program applied to plant operation. Applicability of non-destructive inspection methods to SUS weld metal cladding were confirmed.
