A Knowledge-Informed Large Language Model Framework for U.S. Nuclear Power Plant Shutdown Initiating Event Classification for Probabilistic Risk Assessment
Identifying shutdown initiating event (SDIE) is critical for developing low power shutdown probabilistic risk assessment for nuclear power plants. Existing computational approaches cannot achieve satisfactory performance because of the challenges of unavailable large, labeled datasets, imbalanced event types, and label noise. To address the challenges, we propose a hybrid pipeline that integrates a knowledge-informed machine […]
