Spray System Assessment in Steel Containment of VVER-1000 Reactor with Using Probabilistic Methods
One of the most important safety systems is spray system which is located in steel containment and has been designed to limit radioactive materials release, specially iodine, and to reduce the pressure and temperature in steel containment during events. The functions of mentioned system have been ev...

| description | One of the most important safety systems is spray system which is located in steel containment and has been designed to limit radioactive materials release, specially iodine, and to reduce the pressure and temperature in steel containment during events. The functions of mentioned system have been evaluated by the NPP designer by using probabilistic methods and the Risk Spectrum code. Some of the equipment, however, have not been simulated in the implemented modeling. In this article, by using the probabilistic analysis and the SAPHIRE code, the importance of the spray system’s elements in steel containment has been analyzed and the probability of system failures in various conditions has been calculated. |
