Transition to CASMO-5M and SIMULATE-3K for Stability Analyses of the Swiss Boiling Water Reactors

On butterfly effect in the dynamics of Oskarshamn-2 instability event of 1999

“…At PSI, a stability analysis methodology has been developed based on the S3K code (Dokhane et al, 2013), which is a best-estimate LWR core dynamics code consisting of a full core coupling between neutronics and thermal hydraulics. The neutronics is based on three-dimensional two-Fig.…”

“…As a result, the main principle of the PSI methodology is that the core and vessel models along with the associated physical models and code options are employed in a systematic and consistent manner for all operating conditions and all cycles, covering all types of oscillation modes (e.g. (Dokhane et al, 2013;Dokhane et al, 2014).…”

Análisis de Ruido en Reactores PWR

“…La inestabilidad en reactores BWR es una materia compleja que todavía no está completamente comprendida por lo que existe una gran cantidad de literatura relacionada [14]. También se realiza un importante esfuerzo en el área de la validación de los códigos de planta (TRAC, TRACE y RELAP) acoplados con códigos neutrónicos tridimensionales (PARCS, S3K) ante escenarios de inestabilidad [44], [85].…”
