The Failure Mode Effect Analysis of a Fuel Handling System at Cernavoda Unit 2

摘要

The FMEA(Failure Mode & Effect Analysis)[3] study was performed for a fuelling machine and a fuel handling system at Cernavoda unit 2 in Romania. The resolution level of the FMEA was to the level of specific Cernavoda unit 2 flowsheets and a major component in the mechanical drawings. Failure of the control and instrumentation components is not included in this task. The FMEA study identified the safety functions during fault conditions such as an internal mechanical fault, an internal fire induced effect, an internal flooding induced effect, an earthquake induced effect and a loss of a support service system(the instrument air, the service water & the electrical power). The results would convey the adequacy of a redundancy in a system, the alarms and indications to the operator in the MCR to develop the additional operating procedure to recover abnormal conditions.
