We constructed a deep neural network with infinite multiplication factor vector as input and tried to evaluate the depletion characteristics of the core. It is confirmed that it is possible to predict the depletion characteristics of the maximum power of fuel assembly and the critical boron concentration at high speed and made uncertainty assessment. In some cases, the prediction error is large, so further investigation is necessary.
