Open full text 0 citations

Abstract

The RELAP5/MOD2.5 computer program is being used to simulate hypothetical loss-of-coolant accidents in the Savannah River Site (SRS) production reactors. Because of their unique geometry and thermal-hydraulic design these reactors pose a significant challenge to the simulation capability of RELAP5. This paper focuses on one aspect of the LOCA simulations, air-water flow through the fuel assemblies. Improvements to the RELAP5 code's treatment of wall friction and interfacial friction are described. 9 refs.
