G-SHARE: A Guideline-Based Structured Reasoning Framework for Human-Factor Event Diagnosis
Xingyu Xiao, Mao Du, Jiejuan Tong +2
Human-factor event diagnosis is essential for learning from operational events in nuclear power plants, yet its quality depends strongly on expert interpretation of narrative repor…
ATIM: An ACT-R-Based Task Interface Model for Predicting Operator Action Time in Digital Nuclear Control Rooms
Xingyu Xiao Jonghyun Kim, Jiejuan Tong, Jingang Liang +1
Human performance in digital control rooms is strongly influenced by interface characteristics, which shape visual search, cognitive processing, and motor execution. Accurate predi…
TEAM-SimHRA: A Team-Based Simulation Framework for Human Reliability Analysis Using Multi-Agent Large Language Models
Xingyu Xiao, Jiejuan Tong, Jingang Liang +1
Team-level failure in nuclear control rooms arises not from isolated operator error, but from emergent interaction dynamics, delayed diagnosis, suppressed dissent, and authority-dr…
Quantifying Interface Procedure Coupling Risks in Digital Nuclear Control Rooms: An Event Based Human Reliability Assessment
Xingyu Xiao, Mingwei Xiao, Hongbo Li +3
Digitalization has fundamentally transformed human system interaction in nuclear main control rooms, yet the quantitative mechanisms by which interfaces amplify procedural risks re…
NuHF Claw: A Risk Constrained Cognitive Agent Framework for Human Centered Procedure Support in Digital Nuclear Control Rooms
Xingyu Xiao, Jiejuan Tong, Jun Sun +4
The rapid digitization of nuclear power plant main control rooms has fundamentally reshaped operator interaction patterns, introducing complex soft-control behaviors and elevated c…
InSight-R: A Framework for Risk-informed Human Failure Event Identification and Interface-Induced Risk Assessment Driven by AutoGraph
Xingyu Xiao, Jiejuan Tong, Peng Chen +6
Human reliability remains a critical concern in safety-critical domains such as nuclear power, where operational failures are often linked to human error. While conventional human…
