... Abstract NECP-SARAX is a neutronics code system for fast spectrum reactor developed by Nuclear Engineering Computational Physics Laboratory team of Xi'an Jiaotong University. In previous work, NECP-SARAX has shown high performance on fast spectrum reactor analysis. Recently, neutron-moderating...

... the traditional nuclear design codes, especially for the design of the key parameters, such as core geometry and layout, material composition. In this paper, a neutronics calculation code SARAX and the corresponding multilayer perceptron (MLP) surrogate model were used as simulators for core parameters...
