NS SAVANNAH FUEL DESIGN AND DEVELOPMENT PROGRAM. PRESSURE LOSSES AND FLOW RATES IN FUEL ASSEMBLIES

Pressure losses and flow rates in fuel assemblies for the N.S. Savannah fuel design and development program are examined. Due to slightly modified calculation methods and Small changes in design, the previously committed pressure losses are changed by a small amount, now being 1.30 psi and 1.04 psi for the 2nd and 3rd pass. It is concluded that a decrease in the actual pump flow rate yields 63.1 psi and 2.76 psi pressure losses for the total primary system and the fuel respectively. An extensive appendix illustrates the recommended method used in calculating pressure losses through fuel bundles, consisting of rods, tie plates, and spacer(s).
