CONCEPTUAL FUEL CHANNEL DESIGNS FOR CANDU-SCWR
Nuclear Engineering and Technology, 2008 This paper presents two of the fuel channel designs being considered for the CANDU-SCWR, a pressure-tube type supercritical water cooled reactor. The first is an insulated pressure tube design. The pressure tube is thermally insulated from the hot coolant by a porous ceramic insulator.
