Abstract:

A CONSTITUTIVE PACKAGE WILL BE DEVELOPED FOR THE MODELING OFDIRECT CONTACT CONDENSATION IN ADVANCED COMPUTER CODES FOR NUCLEAR REACTOR ANALYSIS. SINCE CURENT APPROACHES ARE BUILT UPON FLOW REGIME MAPS WHICH DO NOT ACCOUNT FOR CON DENSATION EFFECTS, PRESENT ADVANCED THERMAL/HYDRAULIC CODES ARE UNABLE TO MODEL COLD LEG FLOW BEHAVIOR CONSISTENTLY DURING CONDENSATION, ESPECIALLY IF THE FLOW IS OSCILLATORY. DURING PHASE I, A NEW GENERALIZED METHODOLOGY FOR MODELING CONDENSATION WILL BE DEVELOPED AND ITS FEASIBILITY WILL BE DEMONSTRATED BY IMPLEMENTING A MODEL FOIR A SPECIFIC CONDEN SATION CONFIGURATION IN A SELECTED ADVANCED CODE. THE PROPOSED APPROACH IS AN EXTENSION OF EXISTING EXPERIMENTAL RESULTS AND ANLYTICAL WORK PERFORMED BY CREARE WHERE FLOW REGIME MAPS AND QUANTITATIVE ANALYSIS WERE DEVELOPED FOR VARIOUS CONDENSING SITUATIONS. IN PHASE II, MODELS FOR SELECTED ADDITIONAL CONDENSATION CONFIGURATION WILL BE DEVELOPED, ADDED TO THE GENERAL CONSTITUTIVE PACKAGE, AND ASSESSED AGAINST EXPERIMENTAL DATA FOR CONDENSATION PHENOMENA.
