Natural Circulation Experiments in a UTSG Four-Loop Test Facility

摘要

Additional experiments performed in the four-loop U-tube steam generator (UTSG) facility are described, including single-phase and two-phase natural-circulation tests. Results are included for over twenty experimental conditions including asymmetric cooling, hot and cold leg cold-water injection, nonconderisible gas injection in the upper head, occasional two-phase natural circulation, continuous two-phase natural circulation, and reflux condensation.
