Abstract
The main aim of the research was to design, implement and investigate an Artificial Neural Network (ANN) to predict the behavior of selected parameters of a nuclear reactor core. The studied core was a typical power-generating Pressurized Water Reactor (PWR). The PARCS v3.2 nodal-diffusion core simulator was used to generate training and validation data. The ANN was implemented using Python 3.8 code with Google’s TensorFlow 2.0 library. The effort was based to a large extent on the process of automatic transformation of generated data, which was later used in the process of the ANN development. Various ANN architectures were studied to obtain better accuracy of prediction. In this study, a special focus was put on the prediction of the fuel cycle length for a given core loading pattern. In addition, a conversion of the input data was applied, allowing for very good accuracy of the cycle length prediction (%).
期刊介绍:
Annals of Nuclear Energy provides an international medium for the communication of original research, ideas and developments in all areas of the field of nuclear energy science and technology. Its scope embraces nuclear fuel reserves, fuel cycles and cost, materials, processing, system and component technology (fission only), design and optimization, direct conversion of nuclear energy sources, environmental control, reactor physics, heat transfer and fluid dynamics, structural analysis, fuel management, future developments, nuclear fuel and safety, nuclear aerosol, neutron physics, computer technology (both software and hardware), risk assessment, radioactive waste disposal and reactor thermal hydraulics. Papers submitted to Annals need to demonstrate a clear link to nuclear power generation/nuclear engineering. Papers which deal with pure nuclear physics, pure health physics, imaging, or attenuation and shielding properties of concretes and various geological materials are not within the scope of the journal. Also, papers that deal with policy or economics are not within the scope of the journal.
