Thermalhydraulics and Safety-Related Experiments in Support of the Canadian SCWR Concept Development

Abstract

A Canadian National Program has been established for R&D in various technology areas in support of the Canadian Super-Critical Water-cooled Reactor (SCWR) concept development. The thermalhydraulics and safety projects in the National Program had led to the establishment of infrastructure and capabilities at universities. Current projects focus on the applied research to provide relevant experimental databases for developing or validating prediction methods and analytical toolsets. Several experimental projects are currently being carried out to obtain heat-transfer data with annuli, 3-rod assembly, and 4-rod assembly in refrigerant-134a flow, carbon dioxide flow, and water flow, respectively, and blow-down and natural-circulation data with tubes in water and carbon dioxide flow, respectively. Key scopes of these experimental projects are described. Experimental data obtained from these projects are presented.
