POD-RBF堆芯功率分布测量方法的敏感性分析
Sensitivity Analysis of POD-RBF Core Power Distribution Reconstruction
摘要
Abstract
The online monitoring of the core three-dimensional power distribution is pivotal for ensuring the safe operation of the reactor.In this paper,the PCM software package is utilized to simulate state of 7 000 cores in a pressurized water reactor(PWR)fuel cycle.Additionally,a mapping model is developed to translate the simulated detector signals into a three-dimensional power distribution of the reactor core.The results demonstrate that the POD-RBF method effectively handles high-dimensional data and extracts principal features,thereby enhancing the efficiency and accuracy of 3D power distribution monitoring calculations.By introducing perturbations in the measurements,the robustness of the POD-RBF model is validated,showing its capability to maintain strong performance under uncertainties.Furthermore,the white noise and random failures are introduced in the training set to improve the stability of the POD-RBF model.These findings establish a foundation for future advancements in nuclear energy monitoring technologies and drive further research and development in related fields.关键词
