Abstract:A qualification of the thermal hydraulic system code RELAP5 (reactor excursion leak analysis program) is conducted for the analysis of helically coiled heat exchangers used in a high-temperature environment. A set of closure models based on the past separate effect test are suggested and validated against the measured data in the high temperature engineering test reactor (HTTR). The modified code is then tested for the analysis of a representative nuclear hydrogen production system. The comparison of calculate… 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.
