Quantitative Risk Analysis of High Safety-significant Safety-related DI&C Systems using IRADIC Technology
Two slides prepared for RISA Stakeholder Meeting held on October 14th.
SYSTEMS-THEORETIC HAZARD ANALYSIS OF DIGITAL HUMAN-SYSTEM INTERFACE RELEVANT TO REACTOR TRIP
Human-system interface (HSI) is one of the key advanced design features applied to modern digital instrumentation and control (DI&C) systems of nuclear power plants (NPPs). Conventional design is based on a compact workstation-based system within the control room. The compact workstation provides both a strategic operating environment while also a convenient display for plant status […]

Modeling FLEX Human Actions Using the EMRALD Dynamic Risk Assessment Tool
Most current efforts have modified and applied existing human reliability analysis (HRA) methods to treat human actions related to beyond-design-basis external events in which diverse and flexible coping strategies (FLEX) equipment would be deployed. However, many questions remain regarding the suitability of legacy HRA methods to address FLEX human actions, sparking the need for a […]
