Thermal hydraulic data-base is very useful in the design and analysis
of the proposed Advanced Heavy Water Reactor which relies on natural c
irculation for normal core cooling. Compilation of the thermal hydraul
ic data-base is in progress. Artificial Neural Networks (ANNs), have b
een applied to analyse the consistency and accuracy of the data-base.
The ANN predictions are more accurate and cover wider range of paramet
ers compared to model based predictions. (C) 1998 Elsevier Science Ltd
