Progress on an Experimental Program to Determine the Consequences of Pressure Tube Rupture in CANDU Reactors

Abstract

The first two phases of an experimental program to determine the consequences of pressure tube rupture in a full-scale CANDU fuel channel at operating temperature and pressure have been completed. The results of the first Phase have been reported [I]. In the second phase of this program prototypical Zr-2 calandria tubes were subjected to pressure tube rupture and the results of coolant over-pressure and calandria tube deformation are presented here.
