Numerical Simulation of a Natural Circulation Decay Heat Removal Experiment Conducted at ETEC (Energy Technology Engineering Center): Final Report.

摘要

As a first step to understanding the fundamental physical phenomena occurring during natural circulation removal of decay heat in LMFBRs, the code FLOW3D, obtained from the UKAEA, was used to conduct 2-D direct numerical simulations of one of the test runs conducted on the scaled liquid sodium reactor at ETEC. Results and analysis of the simulations are presented. Results indicate that the code captures the physics of the simulated problem. The code is highly optimized and requires about 10 (mu)-seconds per mesh-cell time-step on a CRAY-XMP. 3 refs., 42 figs.
