Research abstract

A RESEARCH PROGRAM IS PROPOSED FOR THE DEVELOPMENT OF A VALIDATED METHODOLOGY FOR PREDICTING THE EX-VESSEL BUOYANCY-DRIVEN FLOWS IN THE HOT LEG AND STEAM GENERATOR OF A WESTINGHOUSE PLANT, AND IN THE CANDY CANE HOT LEG OF A B&W PLANT. THE PROPOSED PHASE I WORK PLAN CONSISTS OF (A) REVIEWING AVAILABLE WESTINGHOUSE EXPERIMENTAL DATA AND SIMULATING THE EXPERIMENTAL CONFIGURATION, (B) VALIDATING THE MODEL USING THE TEST DATA AND UPDATING THE MODEL, IF REQUIRED, (C) PERFORMING SENSITIVITY CALCULATIONS ASSESSING THE EFFECTS OF FLOW AND GEOMETRIC PARAMETERS ON THE ESTABLISHED FLOW, AND (D) PROVIDING BEST ESTIMATES FOR BUOYANCY-DRIVEN FLOWS WITHIN B&W HOT LEGS.
