Recent Research Developments in Materials Selection for SCWR Vessel Internals

摘要

Supercritical Water-cooled Reactor has attracted many nuclear energy research agencies' interestsby its notable characteristics, such as high safety, high thermal efficiency and simpler systemequipments. Research plan and work have been operated in Japan, USA and European Union sinceend of last century. However, there is no prominent progress in the study of materials, so it is stillnot applied in engineering. In this paper, materials selection rules and performance assessmentsystem for SCWR vessel internals are provided, and a summary of current research work isintroduced.
