東海第二発電所 高経年化技術評価（４０年目）の概要
概要
Tokai No.2 Power Station (Tokai II) has been operated more than 40-years. At 2018,we completed the 40-years Aging Management Technical Evaluation (AMTE), and concluded that most of component and structure would be maintained their integrity by continued existing preservation activities, even assuming the operation period of 60 years. In this paper, we explain several technical matters that were particularly discussed at AMTE, for example, thermal aging for casting stainless steel, neutron irradiation embrittlement, and seismic study for shroud support with SCC.
