Abstract:The external reactor vessel cooling (ERVC) is the key method to ensuring the success of in-vessel retention (IVR), which is one strategy of the Generation III+ advanced light water nuclear reactor to address severe accidents. The heat removal ability of ERVC is limited by the critical heat flux (CHF) on the outer surface of the lower head. In this paper, a heating system with the liquid metal as the intermediate heat medium in the scaled vessel was used to investigate the boiling heat transfer. A three-dimensi… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
