Simulation of a steam generator leak detection experiment in the CCTL

A simulation study to predict the response of leak detectors in the CCTL (Core Components Test Loop) experiment at the Argonne National Laboratory was carried out. A mathematical model was developed for the sodium-water interaction and the subsequent distribution o f the reaction products in a liquid metal steam generator loop. The detectors and the appropriate instrumentation were also modeled and their response to a series o f designed experiments was calculated. The simulation program and the specific CCTL leak detection experiment will be used to identify parameters o f importance for leak detection in LMFBR. Preliminary experimental results show good agreement with the theoretical predictions.
