TEMPERATURE DISTRIBUTIONS IN A REACTOR FUEL PLATE II. PARALLEL PLATES WITH LONGITUDINAL CYLINDRICAL SPACERS

摘要

The effect upon the fuel-plate temperatures of introducing channel spacers into the proposed curved-plate subassembly for the supercritical-water reactor was studied and evaluated. Two arrangements of short cylindrical spacers in the coolant channels were considered.nThe temperature field in the vicinity of a channel spacer was obtained by approximating the appropriate differential equations by dif ference equations and solving these difference equations with an electrical analog.nThe needed local heat-transfer coefficients were estimated on the basis of local heat-transfer experiments performed with water upon a large-scale model of the channel-spacer system.
