Evaluation of thermal mixing data from a model cold leg and downcomer. [PWR]

P.H. Rothe, M.W. Fanning

Open publisher page 1 citations

Abstract

This report describes an evaluation of thermal mixing data obtained in a 1/5-scale, transparent model of the cold leg and downcomer of a Pressurized Water Reactor (PWR). The data are relevant to the phenomenon of fluid and thermal mixing following HPI (High Pressure Injection) of coolant water in a PWR loop. The data are reduced, correlated and compared with theoretically derived values and scaling approaches.
