Special Issue Information

Dear Colleagues,

As a clean energy source, nuclear energy is one of the most important choices to address carbon neutrality and emissions issues, and so the safe and efficient utilization of nuclear energy has always been a research hotspot in the energy industry. The composition of nuclear energy systems is relatively complex, and changes in key parameters of the system have obvious nonlinear characteristics. In addition, the switching of operating conditions in these systems is often achieved through adjusting pumps and valves, and the potential risk of malfunctions during this process is a key factor affecting nuclear safety utilization.

Artificial intelligence technology is highly compatible with nonlinear energy systems due to its advantages in data mining. Intelligent algorithms can effectively solve key problems in parameter prediction, fault diagnosis, and intelligent decision control of nuclear energy systems, ensuring efficient energy utilization and safe system operation.

This Special Issue aims to introduce the latest developments in the research of prediction, classification, and optimization techniques based on artificial intelligence methods in nuclear energy systems.

Topics of interest for publication include, but are not limited to, the following:

  • Research on the application prospects of artificial intelligence in nuclear energy;
  • Intelligent reconstruction of flow and radiation fields in nuclear energy systems;
  • Intelligent mode decomposition and analysis of noise items in nuclear energy system data;
  • Research on health management and smart energy technology for nuclear energy systems;
  • Technologies for constructing proxy models for nuclear energy systems, including but not limited to data-driven proxy models and physics-data-driven proxy models;
  • Time series prediction of key parameters in nuclear energy systems, including but not limited to development of new intelligent algorithm frameworks for nuclear energy systems, online-learning-based prediction of nuclear energy system parameters, etc.;
  • Research on nuclear energy systems based on physical information neural networks;
  • Fault diagnosis of nuclear energy systems, including but not limited to open set recognition technology;
  • Early warnings of nuclear energy system failures based on artificial intelligence;
  • Intelligent optimization of operating parameters for nuclear energy systems;
  • Multiparameter collaborative intelligent control of nuclear energy systems;
  • Intelligent decision-making for nuclear energy systems under complex operating conditions.

Nuclear energy offers a zero-carbon solution to emission challenges, yet nuclear power plant design is constrained by spatial limitations and complex nonlinear parameter interactions. This study develops a hybrid genetic multi-objective optimization framework, NHGA-NSGA-II, by integrating refined NHGA strategies with the NSGA-II technique. Applied to a reactor primary loop system, the framework reveals a fundamental trade-off between system miniaturization (mass/volume) and passive safety (natural circulation and MDNBR). Pareto analysis indicates that Optimization Plan 3 corresponds to the most favorable representative trade-off identified under the present modeling assumptions, optimization settings, and constraint framework, achieving a 20% gain in natural circulation capacity and a 5.9% safety improvement with only a 9.2% cost increase, thereby illustrating a balanced relationship among passive safety, compactness, and economic efficiency within the current scope of the study. The proposed framework offers an effective tool for high-dimensional nonlinear optimization in nuclear engineering. Full article

During the transition of global energy systems toward low-carbon and high-reliability operation, nuclear power plant (NPP) operation and maintenance require environmental perception methods that are safe, energy-efficient, and sufficiently accurate for confined and radiation-risk areas. To address these requirements, this paper proposes an energy-oriented multi-robot collaborative exploration and mapping framework, termed I-WFD-Gmapping-DT. The framework integrates a digital twin (DT) 5+3 model, improved wavefront frontier detection (I-WFD), energy- and risk-aware task allocation, EKF-AMCL-based initial relative pose estimation, and multi-scale Gmapping map fusion. Unlike conventional frontier-based or single-objective exploration methods, the proposed utility function jointly considers discounted information gain, obstacle-sensitive path cost, estimated battery energy, angular dispersion, and safety constraints. A ROS-Gazebo simulation of an NPP-like environment was used for 30 independent runs with randomized seeds and starting perturbations. Compared with WFD-Gmapping, the proposed method increased the three-robot coverage area percentage from 35.6 ± 2.1% to 40.5 ± 1.9%, reduced exploration time by 13.35%, reduced total and used frontier target points by 38.9% and 23.24%, respectively, and reduced estimated energy consumption by 13.9%. Map accuracy was also improved, with AE decreasing from 12.45% to 11.52%, RMSE from 7.85% to 7.18%, and SSIM increasing from 0.78 to 0.83. Additional sensitivity, ablation, runtime, and initial-pose experiments confirm the robustness of the parameter selection and the contribution of the DT-enabled feedback mechanism. The results show that I-WFD-Gmapping-DT can enhance collaborative inspection efficiency, reduce redundant motion and energy consumption, and provide reliable mapping support for intelligent NPP operation and maintenance.
