Discussion on Metal Heat Treatment in Nuclear Power Plant

摘要

To improve mechanical properties and corrosion resistance, heat treatment is applied to the mechanical equipment (equipment and piping, etc.) during manufacture or installation. The nuclear class mechanical equipment with high reliability is required in nuclear power plant, but heat treatment is an important factor which affects reliability of mechanical equipment. To have a better view on issues of metal heat treatment, this paper will provide reference for subsequent heat treatment of mechanical equipment in nuclear power plant by analyzing and summarizing existing problems in heat treatment, especially during the reactor pressure vessel such heat treatment of large forgings, so as to avoid same problems.
