Due to the importance of the reactor protection system (RPS) safety function in nuclear power plants (NPPs), its reliability analysis is one of the essential parts of the probabilistic safety assessment (PSA) of any NPP. The dynamic fault tree (DFT) technique extends the conventional static fault tree (SFT) by considering the time requirements to model and evaluate the NPP safety. This study develops...
The instrumentation and control (I&C) systems for the Lungmen nuclear power plant (LMNPP) are fully digitized based on microprocessor and software technology, and extensively utilize multiplexing networks. That is, undetectable software faults and common cause failures due to software errors may occur, and that will defeat the redundancy of a nuclear power plant (NPP). A diverse backup implementation...
Celem niniejszej pracy było określenie prawdopodobieństwa niedostępności systemu zabezpieczenia reaktora typu PWR firmy Westinghouse. Obiektem referencyjnym, dla którego wykonano analizę była Elektrownia Jądrowa Surry zlokalizowana w Stanach Zjednoczonych. Praca ta obejmuje utworzenie drzewa uszkodzeń i wykonanie analizy ilościowej w programie SAPHIRE oraz oszacowanie niepewności za pomocą metod Monte...
