A Long-term Dependent and Trustworthy Approach to Reactor Accident Prognosis based on Temporal Fusion Transformer

no code implementations28 Oct 2022 Chengyuan Li, Zhifang Qiu, Yugao Ma, Meifu Li

In summary, this work for the first time applies the novel composite deep learning model TFT to the prognosis of key parameters after a reactor accident, and makes a positive contribution to the establishment of a more intelligent and staff-light maintenance method for reactor systems.

Representation Learning based and Interpretable Reactor System Diagnosis Using Denoising Padded Autoencoder

no code implementations30 Aug 2022 Chengyuan Li, Zhifang Qiu, Zhangrui Yan, Meifu Li

With the mass construction of Gen III nuclear reactors, it is a popular trend to use deep learning (DL) techniques for fast and effective diagnosis of possible accidents.

An Unsupervised Learning-based Framework for Effective Representation Extraction of Reactor Accidents

no code implementations28 Aug 2022 Chengyuan Li, Meifu Li, Zhifang Qiu

Thus, the encoder part of the framework is able to automatically infer valid representations from partially missing and noisy monitoring data that reflect the complete and noise-free original data, and the representation vectors can be used for downstream tasks for accident diagnosis or else.

Post-hoc Interpretability based Parameter Selection for Data Oriented Nuclear Reactor Accident Diagnosis System

no code implementations3 Aug 2022 Chengyuan Li, Meifu Li, Zhifang Qiu

The results show that the TRES-CNN based diagnostic model successfully predicts the position and size of breaks in LOCA via selected 15 parameters of HPR1000, with 25% of time consumption while training the model compared the process using total 38 parameters.
