Abstract
A bundle critical heat flux(CHF) database based on subchannel local condition is obtained by analyzing existing bundle experimental database with COBRA-Ⅳcode. Artificial neural network is then applied to train the database and a bundle CHF prediction model is finally obtained. The prediction accuracy of the obtained model is much better than that from general empiric formula, and the root-mean-square of predicated value is 5.63%.
