Emergency Decision Support Techniques for Nuclear Power Plants: Current State, Challenges, and Future Trends

“…These approaches are somewhat complementary to each other. Some researchers integrate PSA with DSA to conduct risk analysis [14,[102][103][104][105]. This hybrid approach synergizes the strengths of both methodologies, enhancing the comprehensiveness and accuracy of risk assessments in NPP operations.…”

Evaluation of risk impact of completion time changes combining PSA and DSA model insight and human reliability analysis

“…The TH model of the RHRS developed is linked with the primary system, which is described in detail in Ref. [37].…”

Aportaciones al modelado de la indisponibilidad de componentes y la fiabilidad humana para la mejora de la seguridad de las centrales nucleares informada en el riesgo

“…Un reactor PWR de 3 lazos ha sido modelado mediante el código TRACE y ejecutado con la versión V5.0 Patch 4 (USNRC, 2014), usando la interfaz de SNAP para simular las secuencias accidentales mostradas en la Figura 6.4. El modelo termohidráulico del RHR desarrollado está conectado con el sistema primario, como se describe en detalle en Martorell, Sánchez-Sáez, Villanueva, & Carlos (2017).…”
