Experimental investigation of steam-line break transients in a recirculating U-tube steam generator.

Abstract

An experimental investigation has been completed of the thermalhydraulic behaviour of a U-tube steam generator under conditions of simulated steam-line rupture. The object of this program was to provide data to verify steam generator models in computer codes used for reactor safety analysis. This paper describes the experiments and the results obtained, specifically, rate of inventory loss, steam generator voiding, liquid level response, and heat removal during the depressurization transient.
