Developmental assessment of the multidimensional component in RELAP5 for Savannah River Site thermal hydraulic analysis

Abstract

This report documents ten developmentalassessmentproblems which were " used to test the multidimensionalcomponent in RELAP5/MOD2.5,Version 3w. The problems chosen were a rigid body rotation problem, a pure radial symmetric flow problem, an r-0 symmetric flow problem, a fall problem, a rest problem, a basic one-dimensionalflow test problem, a gravity wave problem, a tank draining problem, a flow through the center problem, and coverage analysis using PIXIE. The multidimensionalcode calculationsare compared to analytical solutions and one-dimensionalcode calculations. The discussion section of each problem contains informationrelative to the code's ability to simulate these problems. iii Idaho, Inc., managers during the development and assessment of this capabilitywho provided coordination,direction,and resources.
