Conceptual Design of an Experimental Facility to Study the Thermosyphoning Behaviour of CANDU Reactors

Abstract

This paper describes the application of a scaling methodology, presented in a separate paper in this conference, to the conceptual design of an experimental facility to study thermosyphoning behaviour of Candu reactors. The proposed facility comprises a scaled-down single loop of the primary heat transport (PHT) system, and representations of each of the shutdown cooling system, emergency core cooling system, emergency water supply system, feed and bleed system, and a secondary service water system. Instrumentation required to characterize the thermosyphoning phenomena, as well as control and safety systems, are described. A description of a test matrix is provided.
